<P>PROBLEM TO BE SOLVED: To provide a high output type non-aqueous electrolyte secondary battery which has high-charging and discharging characteristics even under a low temperature environment, and has a long life. <P>SOLUTION: In this high-output type non-aqueous electrolyte secondary battery, a carbon material is composed of first graphite powder of which the average particle diameter is 5.0 μm or larger and 20.0 μm or smaller, the specific surface area is 10.0 m<SP>2</SP>/g or larger and 25.0 m<SP>2</SP>/g or smaller, the edge face of a crystal is exposed, and second graphite powder of which the average particle diameter is 5.0 μm or larger and 20.0 μm or smaller, the specific surface area is 1.0 m<SP>2</SP>/g or larger and 5.0 m<SP>2</SP>/g or smaller, and the exposure of the edge face of the crystal is restrained, while a mixing ratio of the first and the second graphite is controlled between 30:70 to 80:20. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
