摘要

PPROBLEM TO BE SOLVED: To provide an anode material for a nonaqueous electrolyte secondary battery capable of offering a nonaqueous electrolyte secondary battery with high vapor-phase growth velocity, excellent productivity, low cost and high discharge capacity, and a method of manufacturing the anode material for the nonaqueous electrolyte secondary battery, an anode collector for the nonaqueous electrolyte secondary battery, and an anode for a nonaqueous electrolyte secondary battery, and an anode for the nonaqueous secondary battery and the nonaqueous electrolyte secondary battery using them. PSOLUTION: The method of manufacturing the electrode material for the nonaqueous electrolyte secondary battery by heating an active substance raw material at a temperature higher than a melting point of an active substance element under reduced pressure to have an active substance which can be alloyed with lithium by vapor growth; the method of manufacturing the electrode collector for the nonaqueous electrolyte secondary battery by vapor-phase film-forming on a cooled surface, the method of manufacturing the electrode for the nonaqueous electrolyte secondary battery by vapor-phase film-forming an active substance layer, a collector layer, and, if need be, another active substance layer in turn on the cooled surface, and then, peeling off a laminated film thus formed; and the nonaqueous electrolyte secondary battery using the electrode are provided.
