Problems solved by technology

[0003] Polymer lithium-ion batteries are generally in a regular shape. Although polymer lithium-ion batteries have gradually been applied to portable electronic devices and wearable health care appliances, regular polymer lithium-ion batteries have brought people A lot of inconvenience. In addition, the polymer lithium-ion battery uses liquid electrolyte inside, which has great potential safety hazards.
[0004] Conventional lithium-ion batteries use liquid electrolytes and single-substrate PE separators, which have great hidden dangers in safety

Abstract

The invention provides a high-voltage special-shaped Li-polymer soft-package battery, belongs to the technical field of batteries and solves the problem that a conventional battery is difficult to be manufactured into a special-shaped battery and is not safe. The high-voltage special-shaped Li-polymer soft-package battery comprises a battery shell, a positive plate and a negative plate, wherein the positive plate and the negative extend out of the battery shell; the battery shell is made of aluminum plastic film and takes the shape of a cuboid which is bent for certain radian; gel electrolyte, an anode mixed with lithium cobalt oxide particles, a cathode taking natural graphite as the main material, and a separating membrane for separating the anode from the cathode, and a PVDF coating is applied on the surface of the separating membrane. The high-voltage special-shaped Li-polymer soft-package battery adopts gel electrolyte so as to avoid the safety problem that leakage, explosion or the like occurs probably when a lithium-ion battery adopting liquid electrolyte is in use.

Description

technical field [0001] The invention belongs to the technical field of batteries, and relates to a high-voltage special-shaped lithium polymer soft package battery. Background technique [0002] Polymer lithium-ion battery technology has matured and been commercialized for many years in the world. As mobile appliances themselves are becoming smaller and thinner, they are convenient for consumers to carry. Polymer lithium-ion batteries are being recognized by more and more designers of portable electronic devices and wearable health care appliances. It has many advantages, such as good safety performance, small thickness, light weight, and large capacity. [0003] Polymer lithium-ion batteries are generally in a regular shape. Although polymer lithium-ion batteries have gradually been applied to portable electronic devices and wearable health care appliances, regular polymer lithium-ion batteries have brought people A lot of inconvenience, in addition, the polymer lithium-i...
