Electrochemical Properties of Chemically Processed SiO(x) as Coating Material in Lithium-Ion Batteries with Si Anode

A SiO(x) coating material for Si anode in lithium-ion battery was processed by using SiCl(4) and ethylene glycol. The produced SiO(x) particles after heat treatment at 725°C for 1 h were porous and irregularly shaped with amorphous structure. Pitch carbon added to SiO(x) was found to strongly affect...

description A SiO(x) coating material for Si anode in lithium-ion battery was processed by using SiCl(4) and ethylene glycol. The produced SiO(x) particles after heat treatment at 725°C for 1 h were porous and irregularly shaped with amorphous structure. Pitch carbon added to SiO(x) was found to strongly affect solid electrolyte interphase stabilization and cyclic stability. When mixed with an optimal amount of 30 wt% pitch carbon, the SiO(x) showed a high charge/discharge cyclic stability of about 97% for the 2nd to the 50th cycle. The initial specific capacity of the SiO(x) was measured to be 1401 mAh/g. On the basis of the evaluation of the SiO(x) coating material, the process utilized in this study is considered an efficient method to produce SiO(x) with high performance in an economical way.
