Abstract
A non-aqueous electrolyte secondary battery has the internal resistance of 10 mΩ/Ah or less (SOC of 50%) and has a power generating element containing the following: a positive electrode obtained by forming, on the surface of a positive electrode current collector, a positive electrode active substance layer containing a positive electrode active substance; a negative electrode obtained by forming, on the surface of a negative electrode current collector, a negative electrode active substance layer containing a negative electrode active substance; and a separator. The positive electrode active substance is made to contain a spinel type lithium manganese composite oxide and a lithium nickel-based composite oxide, and the mixing ratio of the lithium nickel-based composite oxide is 50 to 70% by weight relative to the total 100% by weight of the spinel type lithium manganese composite oxide and the lithium nickel-based composite oxide.
