<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having a smaller irreversible capacity compared with a conventional nonaqueous electrolyte secondary battery, and high input output characteristics especially at low temperatures. <P>SOLUTION: A negative electrode material for a nonaqueous electrolyte secondary battery includes at least three kinds of carbonaceous materials of a carbonaceous material (A), a carbonaceous material (B), and a carbonaceous material (C). A negative electrode of the nonaqueous electrolyte secondary battery and the nonaqueous electrolyte secondary battery use the negative electrode materials. <P>COPYRIGHT: (C)2009,JPO&INPIT |
