Lithium-ion polymer batteries are generally named with 6 digits, indicating thickness/width/height respectively. For example, PL503040 indicates a lithium-ion polymer battery with a thickness of 5.0mm, a width of 30mm and a height of 40mm, where PL indicates the battery It belongs to the polymer category. The production process of lithium-ion polymer batteries generally adopts laminated flexible packaging, so the size change is very flexible and convenient, and there are relatively many models.
Lithium polymer batteries (Li-polymer, also known as polymer lithium-ion batteries) have many advantages such as high specific energy, miniaturization, ultra-thinness, light weight and high safety. Based on this advantage, lithium polymer batteries can be made into any shape and capacity to meet the needs of various products; and it is packaged in aluminum-plastic, and internal problems can be immediately manifested through the outer packaging, even if there are potential safety hazards , it will not explode, it will only bulge.
In the polymer battery, the electrolyte plays the dual function of the separator and the electrolyte: on the one hand, it separates the positive and negative materials like a separator, so that self-discharge and short circuit does not occur inside the battery, on the other hand, it acts as a positive and negative electrolyte like the electrolyte. Conduction of lithium ions between the electrodes. Polymer electrolytes not only have good electrical conductivity, but also have the characteristics of light weight, good elasticity, and easy film formation that are unique to polymer materials.
Apart from cell, let us discuss the PCM(protection board). It equips with IC chip and Moseft to the protection of lithium-ion battery from overcharge、over discharge over current and short-circuit. Following are product performance:
