Paper Title:
Electrochemical Comparison of Chemically or Physically Modified Natural Graphite Anode for Lithium-Ion Batteries
  Abstract

Natural graphite anodes were treated by different methods to improve their cyclability. We tried following methods; heat-treatment at 550oC for graphite powder, addition of carbon black for electrode and VC (vinylene carbonate) in electrolyte. All methods decreased capacity fade rate during constant cycling. The addition of carbon black decreased capacity fade significantly but increased irreversible capacity much at first cycle. Heat-treatment and VC were also effective for cycling and irreversible capacity loss.
