Li-Polymer

Lithium polymer battery (Li-polymer, also known as polymer lithium-ion battery) is a battery with chemical properties. Compared with previous batteries, it has the characteristics of high energy, miniaturization, and lightweight. Lithium polymer battery has ultra-thin characteristics, which can meet the needs of some products to make batteries with different shapes and capacities. In theory, the minimum thickness can reach 0.5mm.
In a lithium polymer battery system, polymer materials are mostly used in cathode and electrolytes. The positive electrode materials are conductive polymer or inorganic compounds used in general lithium-ion batteries. The negative electrode is often lithium metal or lithium carbon interlayer compound, and the electrolyte is solid or colloidal polymer electrolyte or organic electrolyte. Since there is no excess electrolyte in the lithium polymer, it is more reliable and stable.
Based on such advantages, lithium polymer batteries can be made into batteries of any shape and capacity, to meet the needs of various products; And it uses aluminum-plastic packaging, internal problems can be immediately shown through the outer packaging, even if there are potential safety hazards, it will not explode, but will swell. In a polymer battery, electrolyte plays the dual functions of diaphragm and electrolyte: on the one hand, it separates the positive and negative electrode materials like the diaphragm, so that there is no self-discharge and short circuit in the battery; on the other hand, it conducts lithium ions between the positive and negative electrodes like an electrolyte. Polymer electrolyte not only has good conductivity but also has the characteristics of lightweight, good elasticity, and easy film formation of polymer materials. It also conforms to the development trend of lightweight, safety, high efficiency, and environmental protection of chemical power supply.
