Intellectual Property India Publishes Patent Application for 'Iron-Modified Co-Ni Active Sites in CoNi carbonate hydroxide: A Strategy for High-Rate Supercapacitor Materials' Filed by C. V. Raman Global University

MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202631014091 A) filed by C. V. Raman Global University, Bhubaneswar, Orissa, on Feb. 9, for 'iron-modified co-ni active sites in coni carbonate hydroxide: a strategy for high-rate supercapacitor materials.'

Inventor(s) include Dr. Mohua Chakraborty; Ms. Dwititapa Mohanty; and Dr. Dhrubojyoti Roy.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "This patent describes a novel approach to synthesizing iron-modified nickel cobalt carbonate hydroxide (FexNiCo-CH) nanocrystals using a systematic one-step hydrothermal method with site-selective dopant engineering. The present invention is directed to the synthesis of advanced supercapacitor electrode materials that exhibit significantly enhanced electrochemical performance compared to conventional materials. Specifically, this invention provides a comprehensive methodology for controlled incorporation of iron dopants at distinct lattice sites within the nickel cobalt carbonate hydroxide matrix. The synthesized FexNi(1-x)Co-CH materials demonstrate superior specific capacitance values reaching 2898 F/g at 1 Ag-1, substantially outperforming undoped and alternative doped variants. The hydrothermal synthesis process utilizes urea as a source of both carbonate and hydroxyl ions, enabling the formation of a pure phase nanocrystalline material without secondary impurity phases. The resulting nanorod-like architecture with tunable electrochemical properties makes these materials exceptionally promising for next-generation energy storage applications. The invention addresses the critical limitation in supercapacitor technology by providing a cost-effective and scalable synthesis route that can be readily adapted for industrial-scale production. Furthermore, this approach demonstrates site-specific dopant engineering principles that extend beyond supercapacitors to other electrochemical energy storage devices, battery systems, and catalytic applications. The comprehensive characterization data and electrochemical performance metrics validate the superiority of the iron-modified NiCo-CH system for high-rate supercapacitor applications, offering significant commercial potential for the energy storage industry."
