Patent number: 9837643Abstract: A film covered battery has a battery element equipped with a plurality of electrode plates laminated via separators, and an exterior film for hermetically sealing the battery element. A cover film is attached to a hollow present in predetermined regions set on a surface of the exterior film. The predetermined regions are regions obtained by removing overlap regions from projected regions obtained by projecting the electrode plates to the surface of the exterior film, the overlap regions being regions where the projected regions overlap with members interposed between the electrode plates at the outermost layers and the exterior film. It is possible to cover the hollow on the surface, without increasing the thickness of the film covered battery.Type: GrantFiled: December 5, 2011Date of Patent: December 5, 2017Assignees: AUTOMOTIVE ENERGY SUPPLY CORPORATION, NISSAN MOTOR CO., LTD.Inventors: Tsuguhiro Oonuma, Masatomo Mizuta, Yuko Hayashi, Akinori Miura, Tetsuya Yakawa

Patent number: 9793522Abstract: An electrochemical battery can include electrodes (a cathode and an electrode) arranged on respective surfaces of an electrolyte. The electrodes and electrolyte can each be solid state films that can be layered on top of one another to create a stacked structure disposed on a substrate. A polymeric sealant material can be applied over and around the battery stack and a moisture barrier can be formed over the sealant material to thereby prevent moisture from reaching the battery. Conductive terminals electrically coupled to the cathode and anode, respectively, can be formed on a second side of the substrate. As such, the battery can be flip-chip mounted to corresponding mounting pads and thereby connected to other electronics that can receive power from the battery.Type: GrantFiled: October 1, 2014Date of Patent: October 17, 2017Assignee: Verily Life Sciences LLCInventors: Ramesh C.
