Patent ID: 8715860

Claim:
A non-aqueous electrolyte battery comprising: a positive electrode comprising a positive electrode current collector and a positive electrode active material-containing layer formed on the positive electrode current collector, a negative electrode, and a non-aqueous electrolyte, wherein the positive electrode active material-containing layer comprises: particles of an olivine-type lithium phosphate as a positive electrode active material, and first carbon particles having BET specific surface area of 70 m 2 /g or greater; wherein the positive electrode current collector has a thickness of less than 20 μm, and a surface of the positive electrode current collector that is in contact with the positive electrode active material-containing layer has a mean surface roughness Ra of greater than 0.026 μm and smaller than 0.14 μm; and wherein the positive electrode active material-containing layer has a filling density of 1.7 g/cm 3 or greater.
