New Method Discovered for Storing Energy in Glass Windows, Say Researchers


Feb 12, 2024

Researchers at CeNS have developed an affordable and high-performance aqueous transparent battery that can be used to transform glass windows into energy-storing devices. The battery has color modulation capabilities and can be used in smart windows. According to the Department of Science and Technology, the windows remain transparent during the day, allowing sunlight into the room while simultaneously functioning as an energy storage system. At night, the stored energy can power electronic devices within the room, and the battery transitions to a dark blue state for privacy.

The transparent battery features a distinctive design using aluminium-ion battery technology. It integrates a cathode material composed of electro-chromic tungsten oxide and aluminium as the anode, showcasing the charging and discharging process through visible transitions. Dr. Ashutosh Kumar Singh, the lead scientist, said that these transparent energy storage device technologies hold significant potential for integration into smart window applications, offering energy storage capabilities with adaptive transparency.

The use of aqueous electrolytes contributes to the cost-effectiveness, high performance, and elevated safety levels of the battery, making it well-suited for use in smart windows and energy storage applications within modern infrastructures. Dr. Singh mentioned that their work had been recently published in the journal ACS Applied Energy Materials and that their findings hold potential for collaboration with smart glass manufacturers for commercialization efforts.
