    摘要: The present invention provides a nonaqueous electrolyte secondary battery with an excellent packing property and remarkably improved high-temperature cycle characteristics and thermal stability. The nonaqueous electrolyte secondary battery 10 includes a positive electrode plate 11 having a positive electrode active material able to absorb and desorb lithium ions, a negative electrode plate having a negative electrode active material capable of absorption and desorption of lithium ions, and a nonaqueous electrolyte, and the positive electrode active material includes a mixture of material A: LiwNixCoyMnzO2 (where 1.00≦w≦1.30, x+y+z=1, 0.40≦x≦0.50, and 0.30≦y≦0.40) and material B: LiwNixCoyMnzO2 (where 1.00≦w≦1.30, x+y+z=1, 0.30≦x≦0.35, and 0.30≦y≦0.35).

    摘要: To improve cycling characteristics by evening out the battery reaction across different areas of a laminated electrode assembly in a non-aqueous electrolyte secondary-cell battery where the laminated electrode assembly, having tape applied to a top layer, an end face, and a bottom layer thereof, is contained in an outer casing, the tape applied to the periphery of the laminated electrode assembly, configured from a stacked plurality of interleaved separators, cathode plates, and anode plates, extends in the stacking direction across the top layer, end face, and bottom layer of the laminated electrode assembly. Each piece of tape is formed of a base material that is one of styrene-butadiene rubber, styrene rubber, or butadiene rubber.
