Inventor(s) include Nishimura, Kenta; Kato, Taketo; Yamada, Takaya; Nagai, Shota; Inoue, Ryo; Terada, Junpei; and Yamanaka, Taku.
The application for the patent was published on Aug. 29, under issue no. 35/2025.
According to the abstract released by the Intellectual Property India: "Provided is a TFE polymer composition used in a binder for an electrochemical device, the TFE polymer composition making it possible to suppress the generation of any gas inside an electrochemical device cell and the occurrence of any deterioration in the characteristics of an electrochemical device, and to improve the strength of a mixture sheet. This TFE polymer composition, which is used in a binder for an electrochemical device, contains a TFE polymer and at least one compound selected from the group of compounds expressed by general formulas (1) and (2), the TFE polymer composition substantially not containing any moisture. General formula (1): (H-(CF2)m-1-COO)pM1 (In the formula, m is 4-20, M1 is H, a metal atom, NR54 (the R5 moieties may be the same or different, and each represents H or a C1-10 organic group), or the like, and p is 1 or 2.) General formula (2): (H-(CF2)n-SO3)qM2 (In the formula, n is 4-20, M2 is H, a metal atom, NR54 (the R5 moieties are as defined above), or the like, and q is 1 or 2.)."
The patent application was internationally filed on Jan. 18, 2024, under International application No.PCT/JP2024/001343.
