Abstract
A non-aqueous electrolyte secondary battery, comprises positive and negative electrode plates, each comprising a current collector and a material mixture layer carried on each face thereof. A total thickness of the positive electrode material mixture layers on both faces of the current collector is 40 μm to 100 μm. The positive electrode plate has an electrode area of 520 cmto 800 cmper battery capacity of 1 Ah. The negative electrode material mixture layer comprises a graphitizable carbon material. A wide-range X-ray diffraction pattern of the graphitizable carbon material has a peak PX () attributed to a () crystal face at about 2θ=44 degrees, and a peak PX () attributed to a () crystal face at about 2θ=42 degrees. A ratio of an intensity IX () of PX () to an intensity IX () of PX() satisfies: 0<IX ()/IX ()<1.
