In Bengaluru, researchers at the Centre for Nano and Soft Matter Sciences have made a breakthrough in energy storage technology. They have developed a transparent battery that can be used in smart windows, making them affordable and efficient. This high-performance aqueous transparent battery has color modulation capabilities that allow it to transition from a transparent state during the day to a dark blue state for privacy at night.
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. Dr. Ashutosh Kumar Singh, the lead scientist on the project, explained that these 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 infrastructure.
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. This breakthrough is expected to revolutionize the way we store energy in buildings and homes while maintaining transparency and privacy.
