Abstract
A non-aqueous secondary battery includes a positive electrode composite material layer. In a cross-section in a direction of thickness of the positive electrode composite material layer, the positive electrode composite material layer includes a first region including one end portion in a direction intersecting with the direction of thickness, a second region including the other end portion, and a third region lying between the first region and the second region. The first region is composed of a first composite material containing lithium iron phosphate and lithium nickel cobalt manganese composite oxide, and the second region is composed of a second composite material containing lithium iron phosphate and lithium nickel cobalt manganese composite oxide. The third region is composed of a third composite material containing lithium nickel cobalt manganese composite oxide.
