​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.

A li-polymer battery is a type of chemical battery. Compared to conventional batteries, they are characterized by higher energy, smaller size, and lighter weight.

​The li-polymer battery has the feature of ultra-thin. It can be matched to the needs of some products and then made into different shapes and capacities. The theoretical minimum thickness is up to 0.5mm.
