Notes:
Carbon nanofibers and nano-size metal particles were incorporated into the surface of graphite particles. The carbon nanofibers prepared from the decomposition of ethylene over nickelcopper catalyst and the micro-size silicon particles were directly introduced into the graphite particles by mixing. Nano-size tin particles were also incorporated into the graphite particles by impregnation. The three different graphite composites were tested as anode base materials for lithium ion secondary battery. The incorporation of a certain amount of carbon nanofibers into thegraphite electrode improved the cyclic performance as well as the initial charge/discharge capacity. With the introduction of silicon, the initial charge/discharge capacity increased but exhibited the badcyclic characteristics. With the modification with tin, an improved electrochemical performance was observed in both initial charge/discharge capacity and cyclic characteristics
