Patent number: 11769638Abstract: A power storage device includes an electricity storage element, a case, and a sealing member which includes an elastic member. The elastic member contains an elastic polymer and a hindered phenol compound. The hindered phenol compound having a phenol skeleton includes a first hindered group and a second hindered group. The first hindered group is bonded to a first substitution site of the phenol skeleton, and the second hindered group is bonded to a second substitution site of the phenol skeleton. Each of the first substitution site and second substitution site is adjacent to a substitution site of the phenol skeleton to which a phenolic hydroxy group is bonded. One of one or more tertiary carbon atoms in the first hindered group and one of one or more tertiary carbon atoms in the second hindered group are bonded to the first substitution site and the second substitution site, respectively.Type: GrantFiled: March 3, 2020Date of Patent: September 26, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Daisuke Kubo, Doyu Hachisu, Nobuyuki Matsuzawa, Miyoko Masuda

Publication number: 20220359125Abstract: A method for manufacturing an electrolytic capacitor includes a first connection step, a second connection step, a first insertion step, a housing step, and a sealing step. In the first connection step, a first internal lead having a foil shape is connected to a first electrode foil. In the second connection step, after the first connection step, a first external lead having a rod shape is connected to the first internal lead to obtain the first electrode. In the first insertion step, the first external lead is inserted into an insertion port of a sealing plate after the second connection step. In the housing step, the first electrode is housed in a container after the first insertion step. In the sealing step, an opening of the container is closed with the sealing plate after the housing step.Type: ApplicationFiled: July 27, 2022Publication date: November 10, 2022Inventors: YUICHIRO TSUBAKI, KAZUHIRO TAKATANI, MIYOKO MASUDA, KENTA CHASHIRO, SHUMPEI MATSUSHITA
