Lithium polymer batteries are a newer generation of batteries that entered the market in large quantities in 1999. Lithium polymer batteries are basically the same as lithium-ion batteries, except that the electrolyte is a solid polymer rather than a liquid electrolyte.
Lithium polymer batteries have a higher capacity than lithium batteries in the same volume, and there is no memory effect at all (lithium-ion batteries still have a memory effect, just smaller).
Lithium polymer batteries are actually a gel-like substance that is easy to make into various shapes. It is also free of harmful heavy metals, making it a "green battery".
Lithium-polymer and lithium-ion battery technology can replace Ni-Gd batteries. However, the price is too high for the market to fully accept them, especially lithium polymer technology.
Polymer electrolyte materials are ordinary films consisting of a solute in which the host polymer, such as polyethylene oxide, acts as an immobile solvent. The advantages of lithium polymer batteries are that they can be made in any shape and are relatively light, due to the absence of heavy metals and a plastic shell that keeps the electrolyte from leaking. They all perform better, with lithium polymer batteries in their ideal state having a capacity of several thousand mAh and being safer. The solid electrolyte acts like a sealed gel and won't easily disintegrate by spontaneous combustion during charging.
Lithium polymer batteries and lithium batteries are not very different, but lithium polymer batteries still have a lot of their own advantages, the disadvantage is that the price is too high. But in any case, the advantage of lithium polymer batteries used in products and equipment can not be denied.
