Abstract
A composite material (NSCM) has been prepared by mixing nanometer‐scale pure powder and carbon black. The electrochemical performance of NSCM anodes for lithium rechargeable batteries exhibited an extremely high reversible capacity, over , at the tenth cycle. The voltage profile is flat and smooth ranged from 0.4 to vs. . In addition, the cyclic performance is good even at larger current densities. Consequently, NSCM can be used as a novel high capacity anode material for lithium‐ion batteries. ©1999 The Electrochemical SocietyKeywords
