Silicon Nano Wires Anodes for High-Performance Lithium Ion Batteries

We report on the scalable synthesis and characterization of novel architecture three-dimensional high-capacity amorphous Silicon Nanowires (SiNWs)-based anodes, with a quarter of the thickness of common graphite anode. The SiNWs were grown in a novel, catalyst free process, on a thin stainless steel (SS) net. With the use of two and three electrodes coin cells we focus on studying their electrochemical performance and degradation mechanisms. By using our novel, low cost and high mass loading chemical vapor deposition (CVD) procedure we synthesized anodes that have shown stable cycle life for over 600 cycles and provided capacities of up to 6mAh/cm2, very low (
