For meeting the requirements of super-high capacity for the next generation LIB, we develops advanced and unique technologies including hollowing and pressing tech, nano preparation and dispersion tech and surface modification technology, together equipped wuth advanced R&D and quality control instruments, Si based 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 the nanolization and non crystalinity of Si.
As a new anode energy material, Si - based anode material has ultra-high theoretical specific capacity and low lithium removal potential (< 0.5v), and the voltage platform of silicon is slightly higher than that of graphite, so it is difficult to cause lithium dissection on the surface during charging, and the safety performance is better.
The product is characterized with high capacity(≥400Ah/g), high first efficiency(≥85%), good cycle performance, low volume expansion and realization the SNNC and non crystalline of Si. It is widely applied for 3C digital, power tools, electric vehicles (EV/HEV/PHEV).
The mainly type: S400, S420, S450, S500, S650
