New method discovered for storing energy in glass windows, say researchers

Researchers at the Centre for Nano and Soft Matter Sciences in Bengaluru have created a new type of battery that can transform glass windows into affordable energy storage devices. This high-performance aqueous transparent battery has color modulation capabilities that make it ideal for use in smart windows. According to the Department of Science and Technology, these windows remain transparent during the day while storing energy, and at night, the stored energy can power electronic devices within the room while transitioning to a dark blue state for privacy.

The unique design of this transparent battery uses aluminum-ion battery technology, with a cathode material composed of thickness-optimized electro-chromic tungsten oxide (WO3) and aluminum as the anode. The lead scientist, Dr. Ashutosh Kumar Singh, explained that these transparent energy storage devices have significant potential for integration into smart window applications, offering energy storage capabilities with adaptive transparency. The use of aqueous electrolytes makes them cost-effective, high-performing, and safe, making them ideal for use in modern infrastructures.

Dr. Singh also mentioned that commercialization of this technology would require minimal investment and that they are open to collaborating with potential smart glass manufacturers. The research on this transparent battery was recently published in the journal ACS Applied Energy Materials.
