MUMBAI, India, Sept. 5 -- Intellectual Property India has published a patent application (202347049935 A) filed by Chiyoda Corporation; and Kyoto University, Kanagawa, Japan, on July 25, 2023, for 'proton conductor and method for producing same.'
Inventor(s) include Okada Yoshimi; Yasunishi Takuo; Imagawa Kenichi; Eguchi Koichi; Matsui Toshiaki; Muroyama Hiroki; and Ozeki Takashi.
The application for the patent was published on Sept. 5, under issue no. 36/2025.
According to the abstract released by the Intellectual Property India: "[Problem] To provide: a proton conductor suitable for use at a temperature range between 200 C and 600 C; and a method for producing the same. [Solution] This proton conductor is configured such that a portion of lithium ions of Li14-2xZn1+x(GeO4)4 is replaced with protons. The proton conductor has an electroconductivity of at least 0.01 S/cm at 300 C. Here, x is a number equal to or more than zero. Of movable lithium ions included in Li14-2xZn1+x(GeO4)4, 40-70% of the lithium ions may be replaced with protons. Of movable lithium ions included in Li14-2xZn1+x(GeO4)4, 50-60% of the lithium ions may be replaced with protons. The method for producing a proton conductor includes a step for immersing Li14-2 Zn1+x(GeO4)4 in a non-aqueous organic solution containing an acid to cause a portion of lithium ions to be replaced with protons."
The patent application was internationally filed on Aug. 12, 2021, under International application No.PCT/JP2021/029746.
