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.
Most of the domestic polymer batteries are only soft pack batteries, using aluminum-plastic film as the shell, but the electrolyte has not changed. This kind of battery can also be thinned, its low-temperature discharge characteristics are better than that of polymer batteries, and the material energy density is basically the same as that of liquid lithium batteries and ordinary polymer batteries, but because of the use of aluminum-plastic film, it is more efficient than ordinary liquid lithium batteries. light. In terms of safety, when the liquid just boils, the aluminum-plastic film of the soft pack battery will naturally bulge or rupture, and it will not explode.
