Paper Title:
Effect of Phosphorus Doping into the Silicon as an Anode Material for Lithium Secondary Batteries
  Abstract

Carbonaceous material has been used as an anode in lithium-ion secondary batteries due to their good stability during charging and discharging. But this material has the problems like irreversible capacity and low specific capacity that is about 372mAh/g. Because of the problems as stated above, silicon-based materials have been reported as possible anode materials to replace carbon. But they have high electrical resistivity and large volume changes associated with alloying and dealloying of lithium during electrochemical cycling. This study is performed to obtain higher capacity of anode material with a good cycle performance and to reduce electrical resistivity. It is expected that phosphor doping silicon and graphite mixture exhibit higher capacity than that of raw graphite and the doping of phosphorous will be able to decrease electrical resistivity of anode materials.
