  • Publication number: 20180261827
    Abstract: An electrode of a power storage device includes an electrode current collector; and electrode material layers stacked on one side of the electrode current collector, to store and discharge lithium ions. As an anode, each electrode material layer includes a first material and a second material that causes less deposit of the lithium ions on a surface of the anode than the first material, and the farther the electrode material layer is placed from the electrode current collector, the greater a ratio of a weight of the second material becomes. As a cathode, each of the electrode material layers includes a third material and a fourth material that has a higher diffusibility with respect to lithium ions than the third material, and the farther the electrode material layer is placed from the electrode current collector, the less a ratio of a weight of the fourth material becomes.
