Researchers at the Centre for Nano and Soft Matter Sciences in Bengaluru have developed a battery that can turn glass windows into affordable energy storage devices. This battery is a high-performance aqueous transparent battery with 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 the 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.
In conclusion, researchers at the Centre for Nano and Soft Matter Sciences have successfully developed a high-performance aqueous transparent battery with colour modulation capabilities that can be used in smart windows. These transparent energy storage devices offer significant potential for integration into smart window applications, offering energy storage capabilities with adaptive transparency. With their cost-effectiveness, high performance, and safety features, they are ideal for use in modern infrastructures. The commercialisation of this technology requires minimal investment, making it accessible to potential smart glass manufacturers looking to integrate this innovative technology into their products.
