MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202411072173 A) filed by Chairman, Defence Research & Development Organisation, New Delhi, on Sept. 24, 2024, for 'method for fabricating and coating a nanocomposite gel for sodium-sulfur battery.'
Inventor(s) include Kanojia, Sanjay; Mandal, Subhash; Jha, Rajat; Roy, Debmalya; Mukhopadhyay, Kingsuk; Dwivedi, Mayank; Nishant, Joseph; and Nalwa, Kanwar Singh.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "Present disclosure pertains to a method (100) for fabricating a nanocomposite gel for a Sodium-Sulfur (Na-S) battery. Method (100) involves synthesizing (102) a shear-stiffening gel by combining a polar polymer with a non-polar polymer matrix, combining (104) one or more functionalized metal oxide nanoparticles into the matrices and adding (106) a crosslinking agent to mixture of polymers and nanoparticles. Additionally, preparing (108) a polymer and inorganic nanofiller network in an organic solvent and evaporating solvent to form a gel and mixing (110) one or more conductive carbon nanotube materials into the gel. Further, fabricating (112) the battery's electrode by mixing sulfur, carbon black, and polyvinylidene fluoride into a slurry, casted onto an aluminum foil and dried to create a sulfur-based cathode, coating (114) the cathode with a solution of gel in chloroform, dried under vacuum at elevated temperatures, and assembling (116) coated cathode into a sodium-sulfur battery coin cell for energy storage."
