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

Researchers at the Centre for Nano and Soft Matter Sciences in Bengaluru have developed a unique battery that can turn glass windows into affordable energy storage devices. This high-performance aqueous transparent battery has colour modulation capabilities that can be used 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 the transparent battery uses aluminium-ion battery technology, integrating a cathode material composed of thickness-optimized electro-chromic tungsten oxide (WO3) and aluminium 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 commercialisation 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.

According to Dr. Singh, these smart windows could be used in various applications such as offices and homes to reduce energy consumption by storing excess solar energy during the day and using it at night when needed.

The transparent nature of these batteries allows them to be used without disrupting natural light or blocking views outside. This makes them ideal for use in areas where aesthetics is important.

Overall, this technology is expected to revolutionize how we store and use energy in our daily lives.

In conclusion, researchers at the Centre for Nano and Soft Matter Sciences have developed a unique high-performance aqueous transparent battery with colour modulation capabilities that can be used in smart windows. These batteries have significant potential for integration into smart window applications due to their ability to offer energy storage capabilities with adaptive transparency while remaining transparent during the day. The research on this technology was recently published in ACS Applied Energy Materials.

Dr. Singh stated that commercialisation of this technology would require minimal investment and they are open to collaborating with potential smart glass manufacturers.

This technology is expected to revolutionize how we store and use energy in our daily lives by reducing energy consumption while maintaining aesthetics.
