Custom Lithium Ion Battery Pack

How to overcome the problem of battery inflation when making lithium-ion batteries in soft packaging?

APR 16, 2019   Pageview:15

Lithium-ion batteries are a new type of rechargeable batteries developed in the past decade. They are higher than energy, have no memory effect, are green and environmentally friendly, and the discharge voltage is three times that of nickel-cadmium and nickel-metal hydride batteries. Therefore, they have received widespread attention since their inception. It's developing very rapidly. At present, only a few countries have achieved industrialization, among which Japan's industrialization has done the best. China is the earliest developing country to industrialize lithium ion batteries. After the development in recent years, especially under the active promotion of relevant national policies, the domestic lithium-ion battery has achieved rapid progress. The various properties of the products have made considerable progress. The lithium ion battery production chain has been increasingly improved and the degree of industrialization has been increasing. It has formed a situation that competes with the developed countries of the world. With abundant natural resources and Low labor costs, the lithium-ion battery industry has obvious advantages in international competition.

 

Soft packaged lithium-ion batteries are characterized by the basic electrochemical properties of liquid lithium-ion batteries and the unique advantages of polymer lithium-ion batteries in their shape packaging. Liquid electrolytes similar to liquid lithium-ion batteries are used as lithium-ion between positive and negative poles. Transmission medium, The appearance of the packaging is the use of multi-layer plastic composite film. The outstanding advantage of soft packaging lithium-ion batteries is that their production process is simple, the cost is low, and the yield is high. Its goal is to replace the market for polymer lithium-ion batteries. And the stainless steel shell lithium-ion batteries form a competitive state.

 

The most critical technology in the process of making soft packaging lithium-ion batteries is how to overcome the problem of battery inflation. The problem of battery inflation is related to whether the battery seal is good or not, and on the other hand, it is related to the way the battery is formed.
