Nano Silicon Anode Materials, Silicon Anode Materials for Lithium-Ion Batteries
Features: Silicon has high theoretical specific capacity (4200 mAh g-1, graphite negative electrode theoretical specific capacity 372 mAh g-1), low working potential (<0.5 V vs. Li/Li+), abundant reserves and environmental friendliness, etc.
Application: Power batteries are the largest end market in the silicon-carbon anode material industry. The driving force for the application of nano-silicon also comes from major automobile companies, and its direct downstream applications are anode material preparation manufacturers.
Product performance: This process is based on a new and original phase-change process, which can produce high-performance nano-silicon materials (primary particle size less than 100nm, with porous structure) on a large scale (above hundreds of tons) at low cost, and the first Coulombic efficiency can reach 90% , the first charge specific capacity reaches more than 3000 mAh/g, and it has strong oxidation resistance. The composite process is simple and the processing difficulty is greatly reduced.
