Product Detail

For meeting the requirements of super-high capacity for the next generation LIB

1.Production introduce
For meeting the requirements of super-high capacity for the next generation LIB, we develops advanced andunique technologies including hollowing and pressing tech, nano preparation and dispersion tech and surface modification technology,together equipped with advanced R&D and quality control instruments,Sibased material is successfully developed by introducing all these technologies and melting these technologies together.The product is characterized with low volume expansion and long cycling life by controlling and realization thenanolization and non crystalinity of Si.

2. Features
High capacity. High rate performance
Application: it is suitable for the use of super-high capacity lithium ion battery.
