Intellectual Property India Publishes Patent Application for 'Zinc-Bromine Static Battery Device With Modified Cathode Current Collectors' Filed by Offgrid Energy Labs Private Limited; and Offgrid Energy Labs Inc.

MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202411018458 A) filed by Offgrid Energy Labs Private Limited; and Offgrid Energy Labs Inc., New Delhi, on March 14, 2024, for 'zinc-bromine static battery device with modified cathode current collectors.'

Inventor(s) include Suresh Subramanian; and Brindan Tulachan.

The application for the patent was published on Sept. 26, under issue no. 39/2025.

According to the abstract released by the Intellectual Property India: "A zinc-bromine static battery device (100) with a plurality of cells (102) in which a first cell (102a) comprises a first non-conducting frame (104) providing support with a first side (104a) supporting a first cathode current collector (106) and a second side (104b) supporting a first anode current collector (114). The first cathode layer (108), first separator layer (110), and first anode layer (112) are sequentially arranged in the cavity (118) of the first non-conducting frame (104), sandwiched between the first cathode current collector (106) and the first anode current collector (114). A carbon ink layer (116) coats at least one side of the first cathode current collector (106) facing the first cathode layer (108), creating an interface between them."
