Advantages of polymer lithium batteries.lifepo4 battery 12v 200ah

　　1. There is no battery leakage problem, and the battery does not contain liquid electrolyte inside, using colloidal solids.

　　2. Can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm.

　　3. Batteries can be designed into various shapes.

　　4. Battery can bend and deform: Polymer batteries can bend up to about 900 degrees.

　　5. Can be made into a single high voltage: Liquid electrolyte batteries can only be connected in series with several batteries to obtain high voltage. Polymer batteries, due to their lack of liquid, can be made into multi-layer combinations within a single cell to achieve high voltage.

　　6. The capacity will be twice that of lithium-ion batteries of the same size.

　　There are two types of specific capacity for lithium batteries, one is the weight specific capacity, which is the amount of electricity that can be released per unit weight of the battery or active substance; Another type is volume specific capacity, which is the amount of electricity that can be released per unit volume of a battery or active substance. Electricity can be measured in Coulombs, mAh or Ah, or Faraday.

　　Mass to capacity ratio=capacity/mass. For batteries, the capacity is mAh (milliampere hour), which is the current multiplied by time, and sometimes Ah is also useful. The unit of mass is g (grams). Similarly, volume to volume ratio capacity=capacity/volume. From Figure 4, it can be seen that polymer ion batteries have obvious advantages in terms of weight to capacity and volume to weight to capacity, making them the optimal choice for mobile terminal devices.
