  • Patent number: 9887441
    Abstract: A secondary cell is provided that enables cost reduction and stable operation with a simple configuration and greatly exceeds the capacity of a lithium-ion cell. In a secondary cell, a conductive first electrode is formed on a substrate. An n-type metal oxide semiconductor layer, a charging layer for charging energy, a p-type metal oxide semiconductor layer, and a second electrode are laminated. The charging layer is filled with an n-type metal oxide semiconductor of fine particles. By a photoexcited structural change phenomenon caused by ultraviolet irradiation, a new energy level is formed in a band gap of the n-type metal oxide semiconductor. An electron is captured at the newly formed energy level, thereby charging energy. The charging layer is charged by connecting a power source between the first electrode and the second electrode. It is also possible to charge energy by light, using a transparent electrode.

  • Patent number: 9865859
    Abstract: A structure with suppressed thickness and high-density when battery cells of a thin-film-solid secondary battery are stacked. Adjacent battery cells are stacked such that negative electrodes are in contact with each other and positive electrodes are in contact with each other, and arranged such that a taking-out lead electrode smaller than negative or positive electrode surfaces are sandwiched between two negative electrodes in contact with each other or two positive electrodes in contact with each other, and the lead electrodes sandwiched between electrodes of different layers are arranged such that there is no region where all of the lead electrodes simultaneously overlap one another as viewed in a planar arrangement. There are a strip-shaped lead electrode and a linear lead electrode. Further, a conductive sheet forming the electrode is extended to also serve as the taking-out electrode, thereby making it possible to reduce the number of lead electrodes.

  • Patent number: 9865908
    Abstract: There is provided an electrode structure for preventing cracks occurring in a metal electrode due to heating in a manufacturing process in the case of stacking an insulating resin and the metal electrode which are different in thermal expansion coefficient. An electrode for a semiconductor circuit, stacked on a substrate made of an insulating resin, has an electrode structure composed of a main electrode including a slit formed by cutting out a part thereof to prevent occurrence of a crack in a manufacturing process caused by a difference in thermal expansion coefficient from the substrate, and an auxiliary electrode that covers the slit in the main electrode. No slit is provided but a bridge is formed at a portion where the slit in the main electrode and the slit in the auxiliary electrode overlap with each other, thereby eliminating a gap portion where the electrode does not exist.
