摘要： Provided is an electrode including a metal foam as a current collector for obtaining a lithium-ion secondary battery having a high energy density. More particularly, provided is a lithium-ion secondary battery electrode that achieves improved input/output properties (power density) and improved durability, and a lithium-ion secondary battery including the lithium-ion secondary battery electrode. An electrode is formed by providing, in an electrode layer, a region having an excessive amount of an electrolytic solution by forming a region where a current collector made of a metal foam contains no electrode material mixture.
