MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202621013885 A) filed by D. Y. Patil Education Society, Kolhapur, Maharashtra, on Feb. 9, for 'chemically synthesized nickel cobalt hydroxide thin coated electrodes for energy storage and electrocatalytic oxygen evolution reaction (oer) applications.'
Inventor(s) include Dr. Pravin Prakash Pawar; Mr. Vinay Avinash Nimat; Ms. Gouri Mohan Khot; and Prof. Chandrakant Dnyandev Lokhande.
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 claims a hydrothermal method for synthesis of nickel cobalt hydroxide thin coated material on stainless steel (SS) substrate with large area between 1 to 25 cm2. The deposition of nickel cobalt hydroxide on SS substrate is carried out using an aqueous precursor solution of nickel cobalt and urea as hydrolyzing agent. The X-ray diffraction pattern and scanning electron microscopy images reveals that nickel cobalt hydroxide shows a NiCo(OH)2 phase with hexagonal crystal structure and nanosheets like morphology. This nickel cobalt hydroxide thin coated electrodes are tested using electrochemical cyclic voltammetry, galvanostatic charge-discharge, and linear sweep voltammetry techniques. The nickel cobalt hydroxide thin coated electrode exhibits specific capacitance of 638 F g-1 at 0.5 A g-1. Towards the oxygen evolution reaction application, the NiCo(OH)2 thin coated electrocatalyst exhibits an overpotential of 267 mV at 10 mA cm-2 current density. The synthesized nickel cobalt hydroxide through hydrothermal method is a suitable candidate for energy storage and conversion applications."
