In the lithium battery materials, four main materials (cathode, anode, separator, electrolyte) of the high degree of concern, the domestic enterprises are more engaged in.

Which part of the lithium battery material in the industry system also occupy a very important, this report focuses on technical progress and market structure of four kinds of lithium battery accessories.

Plastic film plastic film is becoming more and more important

The car battery 26% of the market, and gradually increase the proportion of. In the plastic film pouch batteries, plastic film cost is accounted for 15%~20%, second only to the cathode material and the diaphragm. The process is very difficult to manufacture plastic film, hard materials and technology.

From the manufacturing process, compared with dry heat, Showa denko represented more excellent products, occupy a larger market. The key material for manufacturing aluminum plastic film also need to be imported, non standard equipment, improve the manufacturing difficulty. The most difficult is mainly reflected in the process, especially the reaction conditions and precision control.

The plastic film market monopoly by Japan and South Korea
