  • Patent number: 9646771
    Abstract: Disclosed is a power storage element including a positive electrode current collector layer and a negative electrode current collector layer which are arranged on the same plane. The power storage element further includes a positive electrode active material layer over the positive electrode current collector layer and a negative electrode active material layer over the negative electrode current collector layer. An electrolyte layer in contact with at least the positive electrode active material layer and the negative electrode active material layer is provided. The electrolyte layer may be a solid electrolyte layer.
    Type: Grant

  • Patent number: 9070950
    Abstract: Disclosed is a power storage element including a positive electrode current collector layer and a negative electrode current collector layer which are arranged on the same plane and can be formed through a simple process. The power storage element further includes a positive electrode active material layer on the positive electrode current collector layer; a negative electrode active material layer on the negative electrode current collector layer; and a solid electrolyte layer in contact with at least the positive electrode active material layer and the negative electrode active material layer. The positive electrode active material layer and the negative electrode active material layer are formed by oxidation treatment.

  • Publication number: 20110254128
    Abstract: An electrode for an energy storage device with less deterioration due to charge and discharge, and a method for manufacturing thereof are provided. Further, an energy storage device having large capacity and high endurance can be provided. In an electrode of an energy storage device in which an active material is formed over a current collector, the surface of the active material is formed of a crystalline semiconductor film having a {110} crystal plane. The crystalline semiconductor film having a {110} crystal plane may be a crystalline silicon film containing a metal element which reacts with silicon to form a silicide. Alternatively, the crystalline semiconductor film having a {110} crystal plane may be a crystalline semiconductor film containing silicon as its main component and also containing germanium and a metal element which reacts with silicon to form a silicide.
