How to repair and maintain ternary lithium-ion batteries? Ternary polymer lithium-ion batteries are characterized by stable voltage, long battery life, and being clean and pollution-free to the human body. They also eliminate the risk of explosion associated with liquid batteries, offering a certain level of safety. So how do you maintain this new generation of lithium polymer batteries? Below, we'll introduce the methods for maintaining lithium polymer batteries.
Ternary polymer lithium-ion batteries: Ternary polymer lithium-ion batteries are lithium-ion batteries that use ternary cathode materials, such as nickel-cobalt-manganese lithium oxide or lithium cobalt oxide. The ternary composite cathode material uses nickel, manganese, and cobalt salts as raw materials, and the ratio of nickel, cobalt, and manganese can be adjusted according to actual needs. Ternary materials and lithium cobalt oxide batteries offer high safety, but the voltage is too low. With a mobile phone (which typically operates at around 3.0V), the capacity will feel noticeably insufficient.
Ternary polymer lithium-ion batteries refer to lithium-ion batteries that use lithium nickel cobalt manganese or lithium nickel cobalt aluminate ternary cathode materials. There are many cathode materials for lithium-ion batteries, the most important being lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, and lithium iron phosphate. Both lithium polymer batteries and lithium-ion batteries are based on lithium. Lithium polymer batteries, also known as lithium polymer batteries, have significant advantages such as high energy density, small size, ultra-thin design, light weight, high safety, and low cost, making them a new type of battery.

How to maintain a ternary lithium-ion battery?
1. First, fully charge the new battery. If you've bought a new battery, it should be fully charged before use. The charging voltage is typically between 4.16V and 4.2V, and should not exceed 4.23V. After fully discharging the battery, it's best to maintain a low discharge current during the discharge process. The final step is to cycle the battery through the above process three times. This is the activation process for maintaining the new battery, which is crucial as it significantly extends the lifespan of the lithium polymer battery.
2. Prevent excessive charges. There are strict requirements regarding the charger's performance and charging speed. If some chargers lack a power-off function after charging, the ternary lithium-ion battery will not stop charging after completion, which will damage the battery. Furthermore, prolonged use of such chargers can also cause the battery to continue charging even after it is fully charged. Therefore, the charging process for lithium-ion batteries should be supervised to prevent battery malfunction, explosion, and damage.
3. Prevent over-discharge. Over-discharging a ternary lithium-ion battery will directly affect its lifespan. If the battery capacity is 2200mAh, the maximum allowable discharge and recharge is 1600mAh. Generally, it is best to discharge the battery to a capacity of 1300mAh to 1600mAh. This charging and discharging method will extend the battery life.
4. Prevent storage. If a fully charged battery cannot be stored for more than three days, it will swell. After a week, another possibility is that the battery will not swell, but after several uses, it will swell. If the battery will not be used for a long time, it is best to discharge it to 3.85V to maintain its optimal condition.
Charge. Lithium-ion battery manufacturers only produce high-quality lithium-ion batteries, which are then stored for a certain period before being sold. This is to stabilize the electrochemical performance of the internal components of the lithium-ion battery, ensuring its quality. Therefore, you must charge it before use.
