摘要
The irreversible capacity of a graphite anode was reduced by CVD coating of carbon from a 5% ethylene in Ar gas at temperatures from 700 to 1000 degreesC. The amount of carbon coated on the graphite powder, surface area of the resultant powder and its electrochemical characteristics depend on deposition parameters. The surface area was reduced by similar to 10% and coulombic efficiency increased by 5 to 92% for the graphite powders coated with carbon at 800 degreesC. The influence of the deposition temperature on the electrode performance has been discussed based on the physical and electrochemical analysis. (C) 2001 Elsevier Science Ltd. All rights reserved.
