ELECTRODE BODY, AND LITHIUM SECONDARY BATTERY EMPLOYING THE ELECTRODE BODY

摘要

An electrode body has a current collector (1), and an electrode layer (4) that is formed on the current collector (1) and that has an electrode active material (2) and a conductive material (3). The concentration of the conductive material at a current collector-side surface of the electrode layer (4) is lower than the concentration of the conductive material at an opposite-side surface that is opposite from the current collector-side surface.
