Hydrothermal Synthesis of Copper Nanowires as Advanced Conductive Agents for Lithium Ion Batteries

Copper nanowires (CuNW) are synthesized via one-pot hydrothermal method and test as advanced conductive agents for lithium ion batteries. Anode prepared with CuNW and graphite show improved rate ability and excellent cycling stability even at high rate. AC-impedance of CuNW added electrode is much lower than that of electrodes containing carbon black only. This implies the CuNW could lower the electronical resistance.
