MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511134259 A) filed by Indian Institute Of Technology, New Delhi, on Dec. 31, 2025, for 'carbon-blend sulfur cathode for room-temperature sodium-sulfur battery.'
Inventor(s) include Kumar, Vipin; Sungjemmenla; Chandra, Mahesh; Soni, Chhail Bihari; and Chandran, Sanjaykumar.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a carbon-blend sulfur cathode for a room-temperature sodium-sulfur battery, comprising a composite material comprising sulfurized polyacrylonitrile, carbonized Prussian blue, and graphite, wherein the composite material comprises amorphous carbon regions and crystalline carbon regions, and wherein the crystalline carbon regions are distributed within the amorphous carbon regions. The present disclosure also provides a method of preparing a carbon-blend sulfur cathode, comprising providing a graphite-Prussian blue precursor by mixing iron (II) sulfate heptahydrate, potassium hexacyanoferrate (III), and graphite in an aqueous solution to form a precipitate, drying the precipitate to obtain a graphite-Prussian blue powder, mixing sulfur, polyacrylonitrile, and the graphite-Prussian blue powder to form a mixture, and calcining the mixture at a temperature in a range of 450 C to 750 C under an inert atmosphere to form the carbon-blend sulfur cathode."
