Abstract
The teaching herein provides an electrode for a lithium-ion secondary battery with excellent input/output characteristics, using an olivine type compound and a layered rocksalt type oxide as its positive electrode active materials. The description herein provides a positive electrode for a lithium-ion secondary battery. This positive electrode for a lithium-ion secondary battery comprises: a positive electrode current collector layer; and a positive electrode composite layer containing an olivine-type compound and a layered rocksalt-type oxide as its positive electrode active materials. The positive electrode composite layer comprises a first region on a side that is closer to a first surface of the positive electrode composite layer, the first surface being opposite to a second surface of the positive electrode composite layer facing the positive electrode current collector layer, and the first region contains the layered rocksalt-type oxide at a higher concentration.
