| 摘要 |
A composite negative-electrode active material, comprising grains of silicon oxide of the formula SiOx (0.05<x<1.95) capable of lithium charge and discharge, carbon nanofiber (CNF) bonded to the surface of silicon oxide grains and a catalyst element capable of accelerating the growth of carbon nanofiber. For example, Au, Ag, Pt, Ru, Ir, Cu, Fe, Co, Ni, Mo or Mn is preferred as the catalyst element. |
