Why is the price of polymer lithium batteries higher than ordinary lithium batteries?

The reason why the price of polymer lithium battery is higher than that of ordinary lithium battery 1. The fundamental difference is the raw material, which is the total source of the different performance of the two. Polymer lithium battery refers to the use of polymer materials in at least one of the three major components of the positive electrode, the negative electrode or the electrolyte. Macromolecules mean large molecular weights, and the corresponding concept is small molecules. Macromolecules have high strength, high toughness and high elasticity. The polymer materials currently developed for polymer batteries are mainly used for positive electrodes and electrolytes. 2. Different shape polymer lithium battery can achieve thinner, arbitrary area and arbitrary shape, because its electrolyte can be solid or colloidal rather than liquid. Lithium batteries use electrolyte and require a solid shell as a The secondary package contains the electrolyte. Therefore, this also makes the lithium battery a new part of the weight. 3. In terms of safety, most of the current polymers are soft-packed lithium batteries, using aluminum plastic film as the outer shell. When organic electrolytes are used inside, they will not explode even if the liquid is hot, because aluminum plastic film polymer batteries use solid or colloidal state. There is no leakage, but it ruptures naturally. But nothing is absolute. If the instantaneous current is large enough and a short circuit occurs, it is not impossible for the battery to spontaneously ignite or burst. The safety accidents of mobile phones and tablet computers are mostly caused by this situation. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
