Patent number: 11404736Abstract: Disclosed is a pouch type metal-air battery. In the pouch type metal-air battery, when the electrolyte inside the cell comes out of the electrode assembly by applying external pressure, the electrolyte does not reach the space partitioned by the gas diffusion layer, the electrode assembly and the exterior material, due to the step caused by the projection part of the gas diffusion layer. As such, a plurality of pores in the exterior material, which corresponds to the space, may not be blocked. Therefore, since oxygen selectively permeated from the exterior material flows into the gas diffusion layer, and flows into the electrode assembly through the diffusion portion of the gas diffusion layer, the contact resistance with pressure may improve and the initial driving conditions and driving reproducibility may be secured.Type: GrantFiled: November 11, 2020Date of Patent: August 2, 2022Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Gwang Seok Oh, Young Suk Cho, Hoi Min Kwon, Su Hyun Kim

Publication number: 20140318106Abstract: A metal-gas battery that utilizes an exhaust gas stream from a combustion engine as reactive gases is provided. Almost constant concentration of exhaust gases are supplied to the metal-gas battery via an existing engine systematic combustion system. The systematic combustion system keeps a definite air fuel mixture (A/F) that acts to enhance the fuel efficiency of the vehicle, and the metal-gas battery leverages the existing vehicle air management system. Exhaust heat of the exhaust gases is sometimes utilized for the heat control of the vehicle, and then the cooled exhaust gases are introduced into the metal-air battery to be consumed during a cathode reduction reaction to create and store electrical energy. The metal-gas battery supports the cleaning of exhausted gases using existing emission catalysts.Type: ApplicationFiled: April 29, 2013Publication date: October 30, 2014Applicant: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Fuminori Mizuno, Paul T.

Patent number: 8835061Abstract: There is provided a metal oxygen battery which uses an oxygen-storing material containing YMnO3 as a positive electrode material, and can reduce the discharge overpotential. The metal oxygen battery 1 has a positive electrode 2 to which oxygen is applied as an active substance, a negative electrode 3 to which metallic lithium is applied as an active substance, and an electrolyte layer 4 interposed between the positive electrode 2 and the negative electrode 3. The positive electrode 2 contains, as an oxygen-storing material, a composite metal oxide obtained by crushing and mixing a yttrium salt, a manganese salt and an organic acid, primarily calcining the mixture, and thereafter, adding a zirconium salt to the obtained primarily calcined material, and secondarily calcining the mixture, the composite metal oxide containing YMnO3 and ZrO2.Type: GrantFiled: July 4, 2012Date of Patent: September 16, 2014Assignee: Honda Motor Co., Ltd.Inventors: Satoshi Nakada, Yuji Isogai, Kiyoshi Tanaami, Takuya Taniuchi, Taichi Goto
