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 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 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.
In conclusion, researchers at the Centre for Nano and Soft Matter Sciences have developed a unique battery that can turn glass windows into affordable energy storage devices with colour modulation capabilities suitable for use in smart windows. This technology has significant potential for integration into modern infrastructure due to its cost-effectiveness, high performance, and safety features using aqueous electrolytes.
As Dr. Singh explains further about this innovative technology: “We believe our transparent batteries can revolutionize how we store and distribute energy in buildings by providing an efficient way to convert sunlight into electricity during the day while maintaining privacy at night.” With this breakthrough discovery, smart glass manufacturers could potentially incorporate these batteries into their products to provide a more sustainable solution for buildings’ energy needs.
Overall, this new development is likely to bring about significant changes in building design and construction by creating more efficient ways of storing and distributing energy within structures without compromising privacy or aesthetics.
