 Abstract
In this study, the electrochemical characteristics of porous silicon/carbon composite anode were investigated to improve the cycle stability and rate performance in lithium ion batteries. In this study, the effect of TEOS and concentration, mixing speed and temperature on particle size of nano silica was investigated using method. Nano porous Si/C composites were prepared by the fabrication processes including the synthesis of nano , magnesiothermic reduction of nano to obtain nano porous Si by HCl etching, and carbonization of phenolic resin. Also the electrochemical performances of nano porous Si/C composites as the anode were performed by constant current charge/discharge test, cyclic voltammetry and impedance tests in the electrolyte of dissolved inorganic solvents (EC:DMC:EMC
