Lithium polymer battery charging method
Polymer lithium battery is a branch of lithium battery developed from lithium battery pack. Lithium polymer battery refers to a lithium ion battery in which all solid state or gel is too electrolyte. Generally, aluminum-plastic composite film is used as packaging material. Lithium batteries generally refer to aluminum shell batteries, the electrolyte is liquid, and the outer packaging material is aluminum shell. Lithium polymer batteries are safer than lithium batteries. Lithium polymer battery is an upgraded product of lithium ion battery.
Li-polymer battery (Li-polymer, also known as polymer lithium battery): with high energy density, smaller size, ultra-thin, lightweight, and high safety It is a new type of battery with many obvious advantages such as performance and low cost. In terms of shape, lithium polymer batteries have ultra-thin features, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can reach can reach 0.5mum.
The precautions for the first charging of the polymer lithium battery are as follows:
1. When charging for the first time, ensure that it is fully charged within 5-6 hours. Because the polymer lithium battery has not been charged or discharged when it is not used at the factory, the charging time should not be too long.
2. When charging for the first time, do not let the polymer lithium battery become completely dead. Under normal circumstances, the power of the new polymer lithium battery will not be too much or too little. When the power of the polymer lithium battery pack shows the last grid, you can prepare to charge.
3. When charging for the first time, choose to charge during the day. Charging at night is prone to overcharging, which can damage the battery. While charging during the day is easy to control the charging time, pay attention to the time when charging.
4. If the polymer lithium battery is charged for the first time in summer, the charger may heat up very quickly, so the charger should not be placed on objects that are easy to heat and burn. Well, don't put it on the seat of the battery car to prevent fire.
5. 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 let the ternary polymer lithium The battery chemical reaction undergoes a complete charging cycle.
1. Buy quality-guaranteed polymer lithium batteries
When buying polymer lithium batteries, you should choose a quality-guaranteed lithium battery manufacturer. Don’t buy low-quality lithium batteries because they are cheap. The product.
2. Charging location
When charging the polymer lithium battery, you should choose a wide area and don’t squeeze it in a small and closed space. This is not safe, and it can also give yourself Response space, and attention should be paid to avoid damp, oily and other environments when choosing a location.
3. Charging time
It is best to choose during the day when charging. Try not to charge the polymer lithium battery overnight. Paying attention to the charging time can also bring danger , There is time to respond.
4. Avoid overcharging
The charging time should be well controlled. It is best not to exceed 8 hours. Overcharging will shorten the life of the polymer lithium battery. It may also cause the voltage to be too negative.
5. Regular maintenance
Buying polymer lithium batteries should also pay attention to regular maintenance. Check the charging circuit and plug from time to time to avoid dangers such as line aging and short circuit.
