Advantages of polymer lithium-ion batteries Polymer lithium-ion batteries are not only safe to use, but also have the advantages of thinness, arbitrary area, and arbitrary shape, and a lighter aluminum-plastic composite film is used for the casing. However, its low-temperature discharge performance may still have room for improvement.
1, good safety performance. This polymer lithium-ion battery structure using aluminum-plastic flexible packaging, as opposed to the metal shell of liquid batteries. In the event of a safety hazard, liquid batteries are easy to explode, while polymer batteries can only be inflated at best.
2, the thickness is small, can be made thinner. General liquid lithium batteries use a custom shell first, and then seal the positive and negative materials. There is a technical bottleneck when the thickness is less than 3.6mm, but the polymer battery does not have this problem. It can be done below 1mm, which meets the needs of cell phones nowadays.

3, light weight, lithium polymer batteries are 40% lighter than steel-cased lithium batteries of the same capacity specifications, and 20% lighter than aluminum-cased batteries.
4, high capacity, polymer battery capacity is 10-15% higher than the same size steel shell battery, 5-10% higher than the aluminum shell battery. It has become the first choice for color screen cell phones and MMS cell phones. MMS cell phones also mostly use polymer batteries.
5、Small internal resistance. Polymer battery resistance is smaller than the general liquid battery. The current domestic polymer battery resistance can even be below 35mΩ, greatly reducing the self-consumption of the battery, extending the service life of the phone. Standby time can completely reach the level of international standards. This kind of lithium polymer battery that supports high discharge current is ideal for remote control models and has become the most promising alternative to NiMH batteries.
6. Customizable shape. Polymer lithium-ion batteries can increase or decrease the thickness of the cells and develop new cell models according to customer needs. Cheap price and short cycle time for mold opening. In order to make full use of the battery casing space and increase the battery capacity.
