Patent ID: 8715859

Claim:
A non-aqueous electrolyte battery comprising: an outer case; a negative electrode housed in the outer case and comprising a current collector and a negative electrode layer formed on at least one of surfaces of the current collector; a positive electrode housed in the outer case and comprising a current collector and a positive electrode layer formed on at least one of surfaces of the current collector and opposed to the negative electrode layer; and a non-aqueous electrolyte filled in the outer case, wherein the negative electrode layer comprises an active material having a lithium absorption/desorption potential of 0.4 V vs. Li/Li + or more, the positive electrode layer comprises an active material containing a layered lithium nickel cobalt manganese composite oxide and a lithium cobalt composite oxide in which at least a part of a surface thereof is coated with a metal compound, the positive electrode layer has a pore volume with a pore diameter of 0.01 μm or more and 1.0 μm or less obtained by the mercury press-in method, the pore volume being 0.06 mL or more and 0.25 mL or less per 1 g of a weight of the positive electrode layer, and a pore surface area within the pore volume range is 2.4 m 2 /g or more and 8 m 2 /g or less.
