Shoko Aoki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrode mixture, method for producing electrode mixture, electrode structure, method for producing electrode structure, and secondary battery
    Patent number: 11322744
    Abstract: To provide an electrode mixture that suppresses gelling of an electrode mixture slurry and maintains a high binding capacity between an electrode active material and a current collector even after an extended period of time has elapsed since an electrode mixture slurry was produced. The electrode mixture includes: a binder composition—containing a first copolymer of vinylidene fluoride and a polar group-containing compound; and a second copolymer of vinylidene fluoride and chlorotrifluoroethylene—; and an electrode active material of lithium oxide having a pH of water when extracted with water of not less than 10.5.
    Type: Grant
    Filed: November 9, 2017
    Date of Patent: May 3, 2022
    Assignee: KUREHA CORPORATION
    Inventors: Kenta Aoki, Shoko Aoki, Shota Kobayashi, Yasuhiro Tada
  • Binder for lithium cell
    Patent number: 10854881
    Abstract: It is an object of the present invention to provide an electrode having superior charge-discharge capacity, even in the case of using an active material containing silicon.
