Why use a non-removable battery design for the phone?

NO.1 Thinner and better performance

In the past, the battery was removable, so there was always some space in the middle, but after becoming non-removable, the battery and the back cover of the phone will be tightly fitted.

Do not have to disassemble of course, and do not have to leave space ah, this naturally reduces the thickness of the inside parts and also has a position to stay, in addition to this point, into a non-removable after the waterproof, dustproof and shockproof performance is also improved, can be said to be a two-in-one approach.

NO.2 more secure

Remember the old days when our cell phones had interchangeable battery plates? Going out with two batteries, out of power to change one, since then also derived in addition to the universal charger, but if you buy these things you will buy the original or buy cheap?

Most people may not take the original way, which leads to the occurrence of safety hazards, if you are not using the original accessories, the chances of safety hazards greatly increase, and the battery is very easy to burn and explode, you also use a not the original, the problem may be blamed on the phone, the phone manufacturer has become a backstabber, and one after another, the reputation is poor, and who is going to buy this phone?

No battery and universal charger, today we use more charging treasure, charging treasure as long as the capacity is large enough, generally can give the phone several times, and can also give several cell phones at the same time charging, simply the existence of a mobile power supply ah, although the volume of large not good to take, but whether it is also not a way to do it. If the cell phone in the past a battery and universal charger, then today's smartphones only use the charging treasure on it.

NO.3 Easy to recycle, environmental protection

Today more and more advocate the theme of environmental protection, if it is a removable battery, the battery is bad, we may throw the battery mixed with other garbage inside the trash, but in fact, the battery is the environment will cause great pollution, there are many heavy metals in the composition. If the battery is non-removable, it will be recycled together with the cell phone, which is more environmentally friendly and easier to recycle.

What do SOC and SOH mean for lithium batteries? The impact of SOC status on lithium batteries?
What is the meaning of lithium-ion battery SOC and SOH? The effect of SOC status on lithium-ion batteries. Lithium-ion battery status includes battery temperature, SOC, SOH, SOS, SOF, and SOE. In order to give full play to the power performance of the battery system, improve the safety of its use, prevent the battery from overcharging and overdischarging, extend the service life of the battery, optimize driving and improve the performance of electric vehicles, the BMS system needs to accurately estimate the state of charge, or SOC, of the lithium-ion battery. SOC is an important parameter used to describe the capacity that can be charged in and out of a battery during use.
What is the meaning of lithium-ion battery SOC and SOH?
SOC refers to the state of charge, also known as the remaining power, which represents the ratio of the remaining capacity of the battery after use for a period of time or long-term use to the capacity of the fully charged state, commonly expressed as a percentage. The value ranges from 0 to 1. SOC=0 indicates that the battery is fully discharged. SOC=1 indicates that the battery is fully charged. Lithium-ion battery SOC cannot be measured directly, and can only be estimated by battery terminal voltage, charge and discharge current and internal resistance. These parameters will also be affected by a variety of uncertain factors such as battery aging, ambient temperature change and vehicle driving state, so accurate SOC estimation has become an urgent problem to be solved in the development of electric vehicles.
SOH refers to the battery capacity, health, performance status, simply said that the battery after a period of time after the performance parameters and nominal parameters of the ratio, the new factory battery is 100%, completely scrapped 0%. It is the ratio of the capacity released by the battery from a certain rate of discharge to the cut-off voltage under full charge to the corresponding nominal capacity, which is simply understood as the limit capacity of the battery. There is a certain relationship between the internal resistance of the battery and SOH. The lower the SOH, the greater the internal resistance of the lithium-ion battery, through the detection of voltage, current, temperature and other data, the internal resistance of the battery is calculated indirectly, and then the SOH is calculated according to the relationship between SOH and the internal resistance of the battery. However, the internal resistance of the battery does not change significantly when the SOH variation range is small, and the resistance value changes greatly when the battery is seriously aged. Therefore, the measurement error of this method will be larger when the SOH variation is small.
The effect of SOC status on lithium-ion batteries
1. The cycle life of lithium-ion batteries and the change law of SOC are consistent with expectations, and the cycle life is significantly increased with the reduction of SOC.
2, SOC is the most important parameter in BMS, involving all other BMS operation work, so the accuracy and robustness of SOC is extremely important. Without a precise SOC, the BMS will not work properly, the battery will often be in a protected state, and the battery life will be shortened. The higher the accuracy of the battery with the same capacity, the higher the range can be.
3, lithium-ion battery in the process of thermal runaway has a considerable part of the heat from the battery storage of electrical energy, usually high SOC state will lead to positive and negative material reactivity increased and thermal stability decreased, so the lithium-ion battery SOC state on the lithium-ion battery in the abuse of the conditions of safety has a crucial impact.
4, different temperatures and different SoCs have different effects on the storage of lithium-ion batteries, 55℃ has the greatest impact on the capacity attenuation of lithium-ion batteries, and 0% and 100% SOCs are not the best state of charge for the most favorable battery performance. The best storage conditions for lithium-ion iron phosphate batteries were investigated by combining various factors.
The above is the meaning of lithium-ion battery SOC and SOH and the impact of SOC state on lithium-ion batteries. The aging of lithium-ion batteries is a long-term gradual process, and the health status of batteries is affected by many factors such as temperature, current ratio, cut-off voltage, and so on. Battery health status assessment has guiding significance for battery use, maintenance and economic analysis, but the battery health status assessment lacks targeted sorting and summary.

The tips of Polymer Battery Maintenance

1. What is charge cycle (or charge/discharge cycle)?

Many people think that the life of polymer batteries is the number of times of charging, in fact, is not correct, strictly speaking should be called charging cycle. A complete charging cycle is to charge 100% of the electricity, and then discharge 100% of the electricity. The life of a lithium battery is about 300-500 full charge cycles. The correct term for the life of a lithium-ion battery should be 300-500 full charge/discharge cycles.

That is to say, suppose a battery overflowing with 100%: used 50%, charged 30%, this is not a complete cycle, a complete cycle is to charge and discharge two 100%, which is actually 40% cycle, and so on, you used 60% again charged

This is actually a 40% cycle. When you use 60% again and charge it at 40%, then you will have a 90% cycle. And so on.

Lithium-ion batteries have no memory effect, so I agree with Apple's assertion that lithium-ion batteries should be used, used some, charged some, not charged too long, and not used to exhaustion. To charge the battery, it is best to use small current to charge, generally with 0.5C-2C charging, small current irritation is small, can better maintain the battery. 3, guard against overcharging and overdischarging, the general set of charging cut-off voltage: 4.25V, discharge cut-off voltage: 3.0V or so, the cut-off voltage of the discharge, but also based on the actual situation, such as playing violent 3D, then the cut-off voltage of the discharge is best to set the cut-off voltage of 3.4V or so, below this cut-off voltage, the best set of 3.4V or so, the cut-off voltage of 3.4V or so. 3.4V or so, below this value, it is easy to cause the whole battery over-discharge due to the instantaneous over-discharge. Be wary of storing a full charge. When not in use for a long time, the lithium-ion battery should be removed and placed in a cool dry place. Never refrigerate and abstain from moisture erosion. Abstain from using it in a hot car. If stored for a long time, the battery will be charged to 40% and placed, or the voltage is saved between 3.75-3.85V.

2. Whether to open the USB charging

Today more and more devices support USB charging, I personally feel that open or not can be, or the above reasons. However, USb charging, see a friend posted that because of insufficient voltage, charging is not enough (PDA have not encountered, can be overflowing, do not understand why the 580 can not), I also encountered the same situation. From the habit, or do not want every time you plug in the USB, have to charge a little bit of electricity, it is a matter of habit, so I myself is the USB charging off. If you don't have a power supply with you, you can turn it on and charge it again, which is convenient anyway. At the same time, do not understand in the case of non-standard voltage, to the cell phone charging, the phone and the battery will not have an impact, in the event that I do not know in the end, I personally prefer to turn off the USB charging as far as possible.

3. What to do when lithium batteries are not in use

Lithium polymer battery self-discharge rate is still a little high, for insurance purposes, if not used, it is best to overflow, and then sealed in a plastic bag and stored. 1-2 months to take out and use once, that is, charging and discharging once, to maintain the activity of lithium ions. The longest do not exceed 3 months, must be taken out to charge and put once. Stored too long without use, will make the lithium ion activity decline, the battery life is affected.

4. How to charge better?

The last small proposal, the original lithium-ion battery is best not to use a miscellaneous charger to charge, use the equipment + original charger, or go to buy the original seat charger. Because miscellaneous chargers with often not standard voltage, current, the original battery is damaged. Especially that old-fashioned charger with discharge function, don't use, accidentally over-discharge, the battery is finished.

5. Lithium-ion batteries used in the environment

Lithium-ion batteries in too hot or too cold environment, the life of lithium-ion batteries also have an impact, so in the heat of the day, do not put the phone in the car or sun exposure; winter if the outside is minus 20 degrees, do not take the phone outside Xuan (long time exposure), or put in a warm pocket, with headphones (do not use bluetooth headset, that is also a lithium-ion battery).

Polymer lithium-ion batteries: charging temperature range of 0 ~ +45 ℃; discharge temperature range of -20 ~ +60 ℃; battery long-term storage environment for: temperature -20 ~ +35 ℃. Ltd. can research and develop customized batteries according to the use of the battery environment, mode and other circumstances.

How is a lithium-ion battery charger different from a lead-acid battery charger?

1. Lithium-ion battery charger

Lithium-ion battery charger is a charger specially designed to charge lithium-ion batteries. Lithium-ion batteries have higher requirements for the charger to protect the circuit, so lithium-ion battery chargers usually have a high degree of control precision, able to charge lithium-ion batteries with constant current and voltage.

Lithium-ion batteries have a high energy-to-weight ratio and energy-to-volume ratio, no memory effect, can be recharged many times, longer service life, and the price is getting lower. These characteristics of lithium-ion batteries have contributed to the development of portable products in the direction of smaller and lighter, making the selection of single-cell lithium-ion battery-powered products are also more and more.

Lithium-ion battery charger products are widely used in scientific research, resource exploration, medical instruments, ultrasonic flaw detection instruments, film and television cameras, digital communications, digital electronics, solar power plants, wireless radios and personal computers and other portable electronic instruments in the field of power supply.

Lithium-ion battery charging control is first in accordance with the stable current charging, and then when the battery voltage rises to 4.2V, the voltage will no longer rise, the charger to test the current, assuming that the current is less than a certain value, the end of the charging. Lithium-ion batteries are active to overcharge, so the protection circuit is messy. For a single nominal 3.6V battery maximum charging rated voltage of 4.2V, promised to overshoot the upper limit of not more than 1%.

Lithium-ion batteries need to use matching chargers when charging, because the battery materials and lithium-ion battery processing technology is different, the charger's technical requirements are not the same, so only need to use a special charger charging lithium-ion batteries to make the longer life, and to prevent potential safety hazards.

2.Lead-acid battery charger

Lead-acid battery charger leads to the use of three-stage charging, quality, performance, charging saturation is high, can enhance the service life of the battery. Lead-acid battery charger charging voltage and battery capacity range, power saturation anti-overcharge, short-circuit automatic protection, high safety factor, low heat, high efficiency, without any damage to the battery.

Lead-acid battery charger is not afraid of short-circuit and misconnection, short-circuit, overload, overcurrent, full-automatic reverse connection protection, very high safety factor, low thermal efficiency. Adequate protection for the normal use of the battery, not due to the quality of the charger and damage.

In fact, lead-acid battery charger in order to overcome the large internal resistance of lead-acid, in constant current charging the charging voltage increased by about 5%, that is, you choose the same voltage charger, lithium-ion battery power supply, the voltage will be higher out of a little bit because of the internal resistance of lead-acid, constant current charging in order to achieve the efficiency of the constant current to the constant voltage rise, so that lithium-ion batteries is very unfavorable.

Lithium-ion battery charger and lead-acid battery charger can not be universal, lead-acid batteries can not be charged lithium-ion batteries, because lithium safety requirements are higher. Lithium-ion batteries are sensitive to overcharging, so the protection circuit is complex. For a single nominal 3.6V battery maximum charging voltage rating of 4.2V, the upper limit of the permitted error is not more than 1%. Lead-acid battery ideal charging current is pulse type, pulse charging to the utility 50-60HZ power supply we use straight rectifier not filtered pulsating DC charging the best.

Classification analysis of lithium-ion battery binder

No matter when, in lithium-ion batteries, there is the use of less than 1~2% of the battery binder, plays an important role in the core, and often because of certain characteristics of the binder polymer for the battery performance brings an unexpected impact.

I. Properties of PVDF

Polyvinylidene fluoride (PVDF) is a polymer material with a high dielectric constant, has good chemical stability and temperature characteristics, has excellent mechanical properties and production, to improve the bonding performance has a positive use, is widely used in lithium-ion batteries as positive and negative binder.

The influencing factors affecting the bonding property of PVDF are closely related to molecular weight size, crystallinity, PVDF modification, cathode material and the type of conductive agent, etc. The larger the molecular weight of PVDF is, the stronger the bonding property is, and the greater the peel strength of the pole piece is. The higher the crystallinity, the closer the molecular chains are stacked, the greater the intermolecular use force, the better the bonding.PVDF used as a binder for lithium-ion batteries has good performance, affecting the use of its tight is the degree of solubility of PVDF powder in the NMP solvent and the effect of moisture.

Second, CMC and SbR

CMC adhesive liquid and metal foil have good adhesion and conductive properties.CMC adhesive liquid viscosity will be reduced with the increase in temperature, easy to absorb moisture and poor elasticity. Styrene-butadiene rubber (SbR) is a water-based binder, a polymer material with good water resistance and aging resistance.

Relatively speaking, SbR has stronger adhesion, but it is easy to break the emulsion under prolonged mixing, thus destroying the structure and reducing its adhesion, and generally, SbR is chosen to be added at the late stage of mixing. At the same time, the dispersion effect of SbR is not as good as CMC, and too much SbR will be dissolved, so we can't use SbR as a binder.

Third, polyacrylic acid (PAA) and its salt binder

Polyacrylic acid is a water-soluble chain polymer, that can form polyacrylate with many metal ions, such as polyacrylic acid and its salt molecular chain also have many oxygen-containing groups (-COOH), which can be formed with the surface of the silica-carbonate active material hydrogen bonding purposes, and giving the active particles and the collector of the strong bonding force between the collector, but also has to alleviate the volume of the silica-based material expansion of the use of the battery is also able to improve the cycling Performance, improve battery life sodium polyacrylate, sodium polyacrylate is soluble in water, has the purpose of thickening, can be used for lithium-ion battery slurry thickener.

Fourth, the polytetrafluoroethylene (PTFE) class

PTFE monomer molecular formula is (CF2CF2), PTFE has good adhesion and can form an elastic network structure in the electrode matrix, in this structure, the active substances are not only in good contact with each other, conducive to the conduction of electrons but also against the electrode due to the charging and discharging caused by the expansion and contraction, lithium-ion batteries can improve the discharge performance and storage life.

Fifth. Polyvinyl alcohol (PVA)

Polyvinyl alcohol (PVA) is a white to slightly yellow solid or powder and is a common water-soluble polymer compound, its molecular chain contains a large number of hydroxyl groups, can be formed on the surface of the carbon anode material hydrogen bonding, has a better adhesion.

Lithium-ion battery binder meets the high bonding in addition to bonding, but also has to bond the electrode after good flexibility, insoluble in the electrolyte, dense, chemical and electrochemical stability and easy to electrode coating, but also to add the low cost, environmental protection, etc., want to meet all the characteristics is more difficult, the binder there is still a long way to go.

Lithium Iron Phosphate Battery Cycle Life and the Factors Affecting Lifetime

As a leader in lithium battery technology, lithium iron phosphate batteries are highly regarded for their excellent performance and long life. When selecting and using LiFePO4 batteries, it is crucial to understand their cycle life and the factors that affect it. In this article, we will take an in-depth look at the cycle life of LiFePO4 batteries and the various factors that affect their life.

First, let's understand what is cycle life? Cycle life is the ability of a battery to complete how many complete charge/discharge cycles while maintaining its rated capacity. In other words, it measures the rate at which a battery gradually wears out over the course of its life. Cycle life provides a more accurate and realistic assessment of life than life measured only in years.

It is important to note that the cycle life of LiFePO4 batteries and the depth of discharge (DOD) of the battery are closely related. (DOD is the depth of discharge, DoD=100% means the battery is fully discharged, DoD=80% means the battery is discharged to 80% of its rated capacity, i.e., 20% of the remaining rated capacity) Take Vantage's IFR26650-30B cell as an example:
Cycle life (100% DOD) ≥ 3000 cycles;
Cycle life (80% DOD) ≥ 6000 times;
Cycle life (50% DOD) ≥ 8000 times.
Many battery cells on the market do not label the depth of discharge when describing the cycle life, such as this type of cycle life without labeling the depth of discharge needs to be considered carefully.

Because of the excellent cycle life of Li-FePO4 battery, Li-FePO4 battery has become the first choice for many applications, such as AGV, UPS, starter batteries, medical equipment, golf carts, home storage/solar energy storage systems, etc. However, even if the same brand of the same capacity battery has the same cycle life, Li-FePO4 batteries are not labeled with the depth of discharge.

However, there are some differences in cycle life even for users of the same brand with the same battery capacity, so the factors affecting the cycle life of the battery are worthy of our attention.

Here are some of the main factors:

Type of Battery: The cycle life of a battery depends on the battery chemistry, here are the average cycle life values for batteries with different chemistries:
Lead-acid batteries: 300 cycles;
Nickel-cadmium batteries: 500 cycles;
Nickel-metal hydride batteries: 800 cycles;
Lithium-ion batteries (cobalt): 1000 cycles;
Lithium ion battery (manganese): 800 cycles;
Lithium iron phosphate battery: 2000 cycles.

Charging and discharging methods: charging and discharging methods will affect the service life of lithium iron phosphate battery. Over-charging and over-discharging may cause permanent damage to the battery, thus shortening the battery life. Therefore, it is necessary to use the charger equipped by the manufacturer to provide the correct voltage and current for the battery.

Temperature: The life of lithium iron phosphate batteries is affected by temperature. High temperatures will accelerate the aging process of the battery, resulting in shorter cycle life; too low a temperature will also affect the reaction rate of lithium iron phosphate battery. Therefore, it is crucial to use the battery within the specified operating temperature range to extend the life of lithium iron phosphate battery.

Storage conditions: Due to the nature of lithium batteries, a slight self-discharge will occur when they are not in use for a long time, so when the batteries are not in use for a long time, they should be stored at room temperature, with the charge maintained at 40-60%, and it is recommended to recharge them every 3 months to avoid the lithium iron phosphate batteries from being in a fully discharged state to ensure their health. For more specific maintenance, please follow the operating instructions and precautions for LiFePO4 batteries provided by the manufacturer.

In summary, cycle life is an important indicator to evaluate the usage time of LiFePO4 batteries. Understanding the factors that affect cycle life, such as the type of battery, charging and discharging methods, temperature and storage conditions, can help maximize the life of LiFePO4 batteries. When selecting and using LiFePO4 batteries, be sure to follow the manufacturer's guidelines for use and maintenance to ensure optimal performance and extended life.
