MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541134486 A) filed by Rajesh Innovations, Eluru, Andhra Pradesh, on Dec. 31, 2025, for 'portable water-activated magnesium battery system with graphite-lead oxide cathode and regulated usb output.'
Inventor(s) include Naraharisetti Rajesh.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a portable water-activated battery system (100) for generating electrical power upon introduction of an aqueous electrolyte. The system (100) comprises a polymer housing (107) defining at least one electrochemical cell having a centrally positioned magnesium anode (112) and a graphite-lead oxide cathode (108) disposed along inner walls with a predetermined inter-electrode spacing. The magnesium anode (112) is removably mounted to a lid (101) through a conductive connector (103), and the lid (101) includes a sealing washer (105) and a hydrophobic vent (104) for controlled hydrogen release while preventing electrolyte leakage. Hydrogen gas generated during operation is collected from at least two cells through tubing and supplied to a proton exchange membrane-based hydrogen fuel cell to generate additional electrical power. Electrical power from the electrochemical cells and the fuel cell is combined and conditioned through a DC-DC converter (115) to provide regulated direct-current output at a common USB port for portable and emergency power applications."
