  • Publication number: 20160036109
    Abstract: Disclosed is a lithium-air battery or particularly, a high voltage lithium-air battery of a laminated type with a high density. The lithium-air battery may be constructed by laminating a plurality of cells, each of which may comprises a cathode that uses oxygen in air as an active material, a lithium metal anode, a separation film interposed between the cathode and the anode and an electrolyte for ion transmission. In particular, an electrically conductive bipolar plate having a flow path for supplying air to the cathode is interposed between a cathode and an anode of adjacent cell when the cells are laminated and an air inlet manifold for distributing air to the air flow path of the respective bipolar plate and an air outlet manifold for allowing the air passing through the air flow path of the respective bipolar plate to be discharged are provided in the lithium-air battery.

  • Patent number: 9190658
    Abstract: Disclosed are a lithium electrode for a lithium metal battery, which uses a solid high-ionic conductor having a three-dimensional (3D) porous structure, wherein a lithium metal or lithium alloy is filled into each pore and dispersed, and a method for manufacturing the lithium electrode. By applying a solid high-ionic conductor having a 3D porous structure, an ion conduction path is secured in the lithium electrode using the solid high-ionic conductor instead of a conventional liquid electrolyte, electrical-chemical reactivity in charging and discharging are further improved, and shelf life and high rate capability are enhanced.

  • Patent number: 9184450
    Abstract: The present invention provides a lithium-air hybrid battery and a method for manufacturing the same, which has a structure in which a liquid electrolyte electrode and a solid electrolyte electrode are stacked on both sides of an ion conductive glass ceramic. That is, disclosed is a lithium-air hybrid battery and a method for manufacturing the same, which has a structure in which a lithium metal negative electrode includes a liquid electrolyte and a porous air positive electrode comprising a carbon, a catalyst, a binder and a solid electrolyte are separately stacked on both sides of an impermeable ion conductive glass ceramic, and the liquid electrolyte is present only in the lithium metal negative electrode.

  • Publication number: 20150118578
    Abstract: Disclosed is a cathode for a lithium sulfur battery comprising a sulfur-containing active material, an electrolyte in which a lithium salt is dissolved in an ether-based solvent, and an additional liquid active material in the form of Li2Sx (0<x?9) dissolved in the electrolyte, and a lithium sulfur battery using the same. The lithium sulfur battery of the present invention has a loading amount of cathode sulfur that is increased to at least about 13.5 mg/cm2 and a structural energy density that is increased from about 265 Wh/kg to at least about 355 Wh/kg as compared with a conventional battery.

  • Publication number: 20130323603
    Abstract: The present invention provides a lithium-sulfur battery using a solid high-ionic conductor in a three-dimensional (3D) porous structure. In particular, at a higher temperature (120° C. or higher) than a melting temperature, the lithium-sulfur battery does not have fluid sulfur leaking outside of a battery cell electrode. The lithium-sulfur battery can be operated at both a high temperature and room temperature. The battery of the invention can be used without performance degradation and with increased ion conductivity at a high temperature, thus improving the battery's power performance.
