Intellectual Property India Publishes Patent Application for 'High Performance, Binder Free Electrode Comprising Nanostructured Yttrium Sulfide For Aqueous And Solid-State Supercapacitors' Filed by Cambridge Institute Of Technology; Dr. Pushpalatha H L; Mr. Vibhu N H; and Dr. Ananda Thipperudra

MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043310 A) filed by Cambridge Institute Of Technology; Dr. Pushpalatha H L; Mr. Vibhu N H; and Dr. Ananda Thipperudra, Bengaluru, Karnataka, on April 4, for 'high performance, binder free electrode comprising nanostructured yttrium sulfide for aqueous and solid-state supercapacitors.'

Inventor(s) include Dr. Pushpalatha H L; Mr. Vibhu N H; and Dr. Ananda Thipperudra.

The application for the patent was published on April 17, under issue no. 16/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to the development of a high-performance binder-free electrode based on nanostructured yttrium sulfide for advanced energy storage applications, particularly in aqueous and solid-state supercapacitors. Conventional supercapacitor electrodes often require polymeric binders and conductive additives to attach active materials to the current collector, which can hinder electron transport, reduce electrochemically active surface area, and ultimately limit device performance. To overcome these limitations, the proposed invention introduces a binder-free electrode architecture in which nanostructured yttrium sulfide is directly grown on a conductive substrate, thereby providing strong adhesion and efficient electrical contact without the need for additional binding agents. The nanostructured morphology offers a large surface area, abundant electroactive sites, and improved ion diffusion pathways, resulting in enhanced electrochemical performance. The fabricated electrode demonstrates high specific capacitance, excellent rate capability, and superior cycling stability, making it suitable for both aqueous electrolyte-based supercapacitors and flexible solid-state devices. The invention further provides a scalable synthesis technique that can be easily integrated into practical energy storage systems for applications in portable electronics, hybrid electric vehicles, and renewable energy storage technologies."
