ELECTRODE FOR LITHIUM ION SECONDARY BATTERY, AND LITHIUM ION SECONDARY BATTERY

To provide an electrode for a lithium ion secondary battery being an electrode for obtaining a lithium ion secondary battery including a foamed metal as a current collector and having a high energy density, and further capable of improving durability and input/output characteristics (output density), and a lithium ion secondary battery using the electrode for a lithium ion secondary battery. [0002] A porous coating layer is disposed on an electrode layer of the electrode for a lithium ion secondary battery using a current collector made of a foamed metal, an electrolytic solution extruded from the electrode layer due to expansion of a negative electrode active material can be absorbed and trapped in the coating layer.
