Description

Vacuum packaging equipment for polymer lithium battery after electrolyte injection

Technical Field

The utility model relates to the technical field of battery vacuum packaging, in particular to vacuum packaging equipment for a polymer lithium battery after electrolyte injection.

Background

The polymer lithium ion battery has the advantages of high voltage, high specific energy, multiple recycling times, long storage time and the like, is widely applied to portable electronic equipment such as mobile phones, digital cameras and portable computers, adopts a novel aluminum plastic packaging film material to replace a steel shell, and has the greatest advantage of good safety performance compared with the traditional steel shell lithium ion battery. In order to ensure the tightness, the most important part of the battery production process is packaging of an aluminum plastic packaging film material, wherein the packaging is to apply certain heat to the aluminum plastic packaging film, so that the functional layers on the two opposite films are fused and bonded, and the isolation of the internal environment and the external environment of the battery is realized. The quality of the package directly determines the isolation of the internal and external environments of the battery and the durability of the battery in a general environment. If the packaging quality is poor, the adverse phenomena of air blowing, liquid leakage, electric property reduction and the like of the polymer lithium ion battery are caused, and the use of the battery is seriously influenced.

The packaging mechanism adopted at present is to use a group of two metal sealing heads with heating sources up and down and opposite to each other, and the cylinder drives the relative pressing to realize heat supply and force application pressurization. Such packaging is prone to over-packaging due to temperature, pressure, etc. The excessive encapsulation is to ensure enough encapsulation strength, and the encapsulation causes the destruction of the functional layer of the aluminum plastic encapsulation film, thereby causing the damage of the shell and the occurrence of the bad phenomena of shell short circuit, shell corrosion, air blowing, liquid leakage and the like.
