Lithium ion battery relative to energy storage lithium battery manufacturers, more "ion" word, is to emphasize the transport of "lithium ion" electrolyte.The familiar 18650 battery contains an adsorbed liquid electrolyte, so all 18650 batteries are lithium-ion.The reason why the 18650 battery was separately proposed from the lithium ion battery is that SONY made a lithium ion charging and discharging pool with a diameter of 18mm and a length of 65.0mm based on the requirements of industrial standard production, which has a wider range of use and is more common.So, in addition to the 18650 standard, there are 16340 batteries.
As for li-ion polymer batteries, the word "polymer" is used to emphasize that the electrolyte is colloidal, solid or semi-solid lithium ion batteries.The fundamental reason why lithium-ion polymer batteries stand out is that "solid polymers" have replaced traditional liquid electrolytes.
The advantages of using colloidal or solid polymer instead of liquid organic solvent electrolyte are that the polymer can be made into any shape to adapt to different equipment, with high adaptability, and the industrial design freedom of the equipment can be guaranteed.Mobile phones, for example (fixed, liquid-electrolyte batteries such as the 18650 are clearly not available on today's smartphones).Second, the electrolyte in the polymer state is more secure: liquid electrolyte in short circuit, under extreme conditions of high temperature and high pressure will explode, the polymer will only expand and bulge out, and no matter how extreme the state will not occur explosive combustion.
