MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096171 A) filed by Kumaraguru College Of Technology on August 09, 2026, for Aluminium-Air Battery And Method For Generating Electrical Energy.
Inventors include Suresh, Thiruppathi; Dr. Samuel Ratna Kumar, Paul Sureshkumar; Dr. Thenmozhi, Ganesan; and Vidhun, Ramakrishnan.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present invention relates to an aluminium-air battery (1) comprising an additively manufactured AlSi10Mg aluminium alloy anode (11) fabricated using a laser powder bed fusion process, a graphite air cathode (12), an alkaline electrolyte (13), an air inlet (14), a current collector (15), and electrical terminals (16). The graphite air cathode (12) comprises graphite powder in an amount ranging from 2.0 g to 5.0 g and polyvinyl alcohol in an amount ranging from 4.0 g to 7.0 g. The alkaline electrolyte (13) comprises 4 M potassium hydroxide, 11.0–13.0 g citric acid and 11.0–13.0 g boric acid. During operation, the aluminium alloy anode (11) undergoes oxidation while oxygen reduction occurs at the graphite air cathode (12) to generate electrical energy. The electrolyte (13) suppresses self-corrosion and hydrogen gas evolution, thereby improving electrochemical characteristics, corrosion resistance, inhibition efficiency and operational durability for electric vehicle and stationary energy storage applications.
