In Bengaluru, researchers from the Centre for Nano and Soft Matter Sciences have created a unique battery that can turn glass windows into affordable energy storage devices. The battery is a high-performance aqueous transparent battery with colour modulation capabilities, perfect for smart window applications. 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 secret to this innovative design lies in aluminium-ion battery technology that integrates a cathode material composed of thickness-optimized electro-chromic tungsten oxide (WO3) and aluminium as the anode. Dr. Ashutosh Kumar Singh, the lead scientist on the project, 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.
The development of this new battery technology could revolutionize the way we think about energy storage and usage in our homes and buildings. With its ability to store energy during the day while remaining transparent, it could be used in smart windows to power electronic devices without disrupting natural light or privacy.
In conclusion, researchers at the Centre for Nano and Soft Matter Sciences have developed an innovative solution for turning glass windows into affordable energy storage devices using a high-performance aqueous transparent battery with colour modulation capabilities. This technology has significant potential for integration into smart window applications and could be used to improve energy efficiency in modern infrastructure while maintaining privacy concerns.
Overall, this new development highlights how innovation continues to drive advancements in various fields of science and engineering towards more sustainable practices and efficient solutions.
