Ternary polymer lithium battery refers to a lithium battery in which the positive electrode material uses lithium nickel cobalt manganese oxide (Li(NiCoMn)O2) ternary positive electrode material. The ternary composite positive electrode material is made of nickel salt, cobalt salt, and manganese salt. The ratio of nickel-cobalt-manganese can be adjusted according to actual needs. Compared with lithium cobalt oxide batteries, batteries with ternary materials as the positive electrode are safer, but the voltage is too low, and there will be obvious problems when used in mobile phones (the cut-off voltage of mobile phones is generally around 3.0V). The feeling of insufficient capacity.
The precautions for charging the ternary polymer lithium battery for the first time are as follows:
- When charging for the first time, make sure it is fully charged within 5-6 hours. Because the ternary polymer lithium battery has not been charged and discharged when it is not in use at the factory, so the charging time should not be too long.
- When charging for the first time, don't let the ternary polymer lithium battery run out of power completely. Under normal circumstances, the power of the new ternary polymer lithium battery will not be too much, nor too little. When the power of the ternary polymer lithium battery is displayed on the last grid, it can be ready to charge.
- When charging for the first time, choose to charge during the day. Charging at night is prone to overcharging and damages the battery. It is easy to control the charging time when charging during the day, so pay attention to the time when charging.
- If you charge the ternary polymer lithium battery for the first time in summer, the charger may generate heat very quickly, so the charger should not be placed on objects that are prone to heat and burn, and it is best not to place it on on the seat of the battery car to prevent fire.
- When charging for the second time, you can choose deep discharge, and then charge for a long time. This charge can last for 8-9 or even 10 hours, in order to allow the chemical reaction of the ternary polymer lithium battery to complete a complete charge cycle.Also read:How to charge golf cart batteries
- Buy ternary polymer lithium batteries with guaranteed quality When purchasing ternary polymer lithium batteries, you should choose a lithium battery manufacturer with guaranteed quality, and don't buy inferior products just because you want to be cheap.
- Charging location When charging a ternary polymer lithium battery, you should choose a wide area. Don’t squeeze into a small and closed space. This is not safe, but it can also give you room to react. Avoid damp, oily and other environments. 3. Charging time It is best to choose during the day when charging. Try not to charge the ternary polymer lithium battery overnight. Paying attention to the charging time can also give you time to deal with danger.
- Avoid overcharging. The charging time should be well controlled, preferably not more than 8 hours. Failure to overcharge will shorten the service life of the ternary polymer lithium battery, and may cause the voltage to be too negative.
- Regular maintenance When buying a ternary polymer lithium battery, you should also pay attention to regular maintenance, check the charging line and plug from time to time, to avoid the danger of line aging, short circuit and other things.
Ternary polymer lithium battery refers to a lithium battery in which the positive electrode material uses lithium nickel cobalt manganese ternary positive electrode material. , lithium iron phosphate, etc. At present, batteries of ternary materials have replaced lithium cobalt oxide batteries, which were widely used before, and are widely used in the field of notebook batteries. It is a relatively balanced material in terms of capacity and safety, and its cycle performance is better than that of normal lithium cobalt oxide. Due to technical reasons in the early stage, its nominal voltage is only 3.5-3.6V, which is limited in the scope of use. But so far, with the development of the formula With continuous improvement and perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide battery.
