PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery which can be also applied to a large-sized battery, is superior in safety. SOLUTION: After lithium manganate for an active material, a conductive material and polyvinyliden fluoride as binding agents are set 85:10:5, in a mass ration, and N-methyl-2-pyrrolidone is added to the mixture as a dispersive solvent, the kneaded slurry is applied onto aluminum foil. Acetylene black, and at least either one of low graphitized graphite, in which a spacing d002 of the 002 inter-planar distance of carbon lattice is 0.337 nm or larger, and its length in the direction of the C axis is 12 nm or smaller, or amorphous carbon crushed to a prescribed particle size and classified are used for the conductive material. |
