Abstract
Using a non-aqueous electrolyte secondary battery containing lithium iron phosphate as a positive electrode active material and graphite as a negative electrode active material, a low-cost, high energy density battery is provided that exhibits good performance at high rate current and good cycle performance even at high temperature. The non-aqueous electrolyte secondary battery has a positive electrode having a positive electrode current collector and a positive electrode active material-containing layer formed on a surface of the positive electrode current collector, the positive electrode active material-containing layer containing a conductive agent and a positive electrode active material including lithium iron phosphate, a negative electrode containing a carbon material, and a non-aqueous electrolyte. The non-aqueous electrolyte contains vinylene carbonate.
