Abstract
To provide a lithium ion secondary battery configured to suppress a decrease in charge capacity. A lithium ion secondary battery, wherein the lithium ion secondary battery uses a lithium metal precipitation-dissolution reaction; wherein the lithium ion secondary battery comprises a cathode layer, an anode layer, and an electrolyte layer disposed between the cathode layer and the anode layer; wherein the cathode layer contains a cathode active material that can occlude and release a lithium ion; and wherein the anode layer contains a Mg element, an In element, a Sn element and a Li element.
