Abstract:
1. A high power output non-aqueous electrolyte secondary battery comprising: a positive electrode including a lithium-containing composite oxide; a negative electrode including a carbon material capable of absorbing and desorbing lithium ions; and a non-aqueous electrolyte, wherein said carbon material comprises a graphitizable carbon material, and said graphitizable carbon material has an average particle size of 5 μm to 15 μm, and wherein in a diffraction pattern of said graphitizable carbon material measured by wide-angle powder X-ray diffractometry, a ratio: I(101)/I(100) of a peak intensity I(101) attributed to a (101) plane to a peak intensity I(100) attributed to a (100) plane satisfies 0<I(101)/I(100)<1.0, and a ratio: I(110)/I(004) of a peak intensity I(110) attributed to a (110) plane to a peak intensity I(004) attributed to a (004) plane satisfies
