Electrochemical Characteristics of Nano-Silicon/Graphite Composite for the Anode Material of Lithium Secondary Batteries
Silicon coated graphite particles prepared by gas suspension spray method were used as a raw material for the battery anode, which showed high specific capacity and good cycle performance. The improvement of electrochemical performance seems to be due to the formation of amorphous silicon-carbon black composite layer on the surface of the graphite particles. It has a stable structure under repeated volume expansion and contraction.
