Polymer lithium battery is developed on the basis of liquid lithium ion battery. Its positive and negative materials are the same as those of liquid lithium ion battery, but it uses gel electrolyte and aluminum-plastic film as its outer packaging, so it has lighter and thinner, higher energy density and safety characteristics, and is widely favored by customers at home and abroad. 1. Higher energy density: Under the same capacity, the weight of polymer battery is 40% lighter than that of steel shell battery and 20% lighter than that of aluminum shell battery. 2. Better security:Polymer batteries are packaged with aluminum-plastic film, which is safer than steel shell batteries. Once potential safety hazards occur, they will not catch fire or explode, but will be flatulent; And 3, that design is flexible, and the shape can be customize: the shape of the battery can be customized accord to the size of a battery compartment of a customer product, the price is low, and the cycle is short. And 4, that discharge characteristic is good: the polymer battery adopt a colloidal electrolyte, and compared with a liquid electrolyte, the discharge characteristic of the colloidal electrolyte is more stable, and the platform is high. And 5, the design of the protection board is simple: the safety of the polymer battery is extremely high, secondary protection devices such as PTC and fuses can be omitted, and the cost is reduced.
