Title:
Quality for nonaqueous electrolyte rechargeable batteries of cathode active material
Document Type and Number:
Japanese Patent JP6128196
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a positive electrode active material for a nonaqueous electrolyte secondary battery, which enables the materialization of a nonaqueous electrolyte secondary battery having a high energy density and a high output characteristic.SOLUTION: A positive electrode active material for a nonaqueous electrolyte secondary battery comprises a lithium transition metal composite oxide expressed by the following general formula: Li(NiCr)(MnTi)MgAlMO(where 1.00≤a≤1.30, 0.020≤x≤0.200, 0.006≤y≤0.070, 0.450≤α≤0.550, 0≤β≤0.015, 0≤γ≤0.035, 0≤δ≤0.010, and M represents at least one element selected from a group consisting of Na, K, Ca, Sr, Ba, Ga, Co, Zn, Si, Ge, Zr, Hf, Sn, Ta, Nb, P, Bi, Mo and W).SELECTED DRAWING: Figure 1
