Patent number: 10403927Abstract: In one embodiment, a thin film solid state lithium ion secondary battery is able to be charged and discharged in the air and is able to be manufactured stably at a favorable yield. The thin film solid state lithium ion secondary battery has an electric insulating substrate formed from an organic resin, an inorganic insulating film provided on the substrate face, a cathode-side current collector film, a cathode active material film, a solid electrolyte film, an anode potential formation layer, and an anode-side current collector film. The cathode-side current collector film and/or the anode-side current collector film is formed on the inorganic insulating film face. The anode potential formation layer is a layer formed from the same material as that of the cathode active material film or a material different from that of the cathode active material film and is a layer provided for forming anode potential at the time of discharge.Type: GrantFiled: May 3, 2017Date of Patent: September 3, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Yuichi Sabi, Katsunori Takahara, Hiroyuki Morioka, Tatsuya Furuya, Koichiro Hinokuma, Reina Ichikawa, Yui Senda, Momoe Adachi

Patent number: 9819052Abstract: A secondary battery capable of safely improving a battery performance is provided. An electrolyte with which a separator 13 is impregnated contains an alkyl sulfone and a low-polar solvent (a solvent having a relative permittivity of 20 or less) together with an aluminum salt. The alkyl sulfone facilitates the redox reaction of aluminum, and further reduces the reactivity of the electrolyte. Additionally, the low-polar solvent suppresses the block of the redox reaction of aluminum. In charge and discharge, it becomes easy to electrochemically efficiently precipitate and dissolve aluminum, and further to inhibit the corrosion of a metallic exterior package member or the like.Type: GrantFiled: April 9, 2010Date of Patent: November 14, 2017Assignee: SONY CORPORATIONInventors: Yui Senda, Kenta Yamamoto, Yuri Nakayama, Reina Ito
