Patent number: 10361465Abstract: A secondary battery is disclosed. The secondary battery has a bipolar electrode, an electrolyte layer, and a porous insulator. The bipolar layer includes a positive electrode layer formed on one surface of a collector foil and a negative electrode formed on the other surface of the collector foil. The electrolyte layer is famed at least on a surface of at least one of the positive electrode layer and the negative electrode layer. The porous insulator is formed to a lateral surface of at least one of the positive electrode layer, the negative electrode layer, and the electrolyte layer. The electrolyte layer is laminated by at least one layer relative to the bipolar electrode to configure a bipolar battery. The porous insulator also includes an inorganic particle and a reactive agent for lowering a fluidity of the liquid electrolyte bleeding from the electrolyte layer.Type: GrantFiled: March 16, 2017Date of Patent: July 23, 2019Assignee: HITACHI, LTD.Inventors: Shimpei Amasaki, Yusuke Kaga, Kazuaki Naoe, Makoto Abe, Etsuko Nishimura, Akihiko Noie
