Patent number: 8617749Abstract: A non-aqueous electrolyte and a lithium secondary battery using the same are provided, which satisfy both flame retardancy and charge-discharge cycle characteristics, and attain a longer lifetime of the battery. A mixture of a chain carbonate, vinylene carbonate, a fluorinated cyclic carbonate and a phosphate ester is used as the non-aqueous electrolyte. It is desirable that the phosphate ester includes trimethyl phosphate and a fluorinated phosphate ester. Further, it is desirable that ethylene carbonate is further contained.Type: GrantFiled: February 17, 2011Date of Patent: December 31, 2013Assignee: Hitachi, Ltd.Inventors: Toshiyuki Kobayashi, Kazushige Kohno

Publication number: 20130344397Abstract: A composite solid electrolyte includes a monolithic solid electrolyte base component that is a continuous matrix of an inorganic active metal ion conductor and a filler component used to eliminate through porosity in the solid electrolyte. In this way a solid electrolyte produced by any process that yields residual through porosity can be modified by the incorporation of a filler to form a substantially impervious composite solid electrolyte and eliminate through porosity in the base component. Methods of making the composites are also disclosed. The composites are generally useful in electrochemical cell structures such as battery cells and in particular protected active metal anodes, particularly lithium anodes, that are protected with a protective membrane architecture incorporating the composite solid electrolyte.Type: ApplicationFiled: November 9, 2012Publication date: December 26, 2013Inventors: Steven J. Visco, Lutgard C. De Jonghe, Yevgeniy S. Nimon

Publication number: 20130323603Abstract: 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.Type: ApplicationFiled: October 22, 2012Publication date: December 5, 2013Applicant: HYUNDAI MOTOR COMPANYInventors: Hee Yeon Ryu, Yoon Ji Lee, Hee Jin Woo, Jun Ki Rhee

Patent number: RE44705Abstract: A battery capable of improving the storage characteristics and the cycle characteristics is provided. The battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. A solvent of the electrolytic solution contains a given sulfone compound such as bis(trimethylsilyl)-2,2-difluorosulfoacetate. Compared to a case that a solvent does not contain the foregoing sulfone compound, the chemical stability of the electrolytic solution is improved, and the decomposition reaction of the electrolytic solution is suppressed.Type: GrantFiled: February 1, 2013Date of Patent: January 14, 2014Assignee: Sony CorporationInventors: Masayuki Ihara, Hiroyuki Yamaguchi, Tadahiko Kubota
