The difference between lithium polymer batteries and others

​The principle of a li-polymer battery is the same as liquid lithium, the main difference is that the electrolyte is different from liquid lithium. The main structure of the battery includes three elements: a positive electrode, a negative electrode, and an electrolyte. The so-called lithium polymer battery means that at least one or more of these three main structures use polymer materials as the main battery system.

Safety issues of li-polymer battery

​Li-polymer batteries are a branch of lithium-ion batteries developed from lithium-ion batteries. Lithium polymer batteries are lithium-ion batteries that are completely solid or gel-like electrolytes. Aluminum-plastic composite film is generally used as the packaging material. Lithium-ion battery generally refers to the aluminum case battery. The electrolyte is a liquid and the outer packaging material is an aluminum case. Lithium polymer batteries are safer than lithium-ion batteries. The li-polymer battery is an upgrade of the lithium-ion battery.
