Bengaluru scientists develop novel battery tech which can serve as an alternative to traditional Lithium-ion batteries 

Researchers from the Centre for Nano and Soft Matter Sciences (CeNS), in collaboration with IISc’s Centre for Nano Science and Engineering (CeNSE), have developed a novel battery technology that could serve as an alternative to traditional lithium-ion batteries commonly used in phones, laptops, electric vehicles, and wearable devices.

According to the Department of Science and Technology this new battery uses aluminum and a water-based solution. “This combination makes it safer, cheaper, and much kinder to our environment. It could protect from battery explosions and environmental hazards, and also reduce the power requirement of our devices,” states the department.

The hazards

The commonly used Lithium-ion batteries are prone to overheating and explosion.

The department further stated that this innovative battery stores energy efficiently and reliably, maintaining 96.77% of its power after 150 charge-discharge cycles, limiting reduction in battery life over extended daily use. “It stays functional even when bent or folded completely in half. To showcase this, scientists powered an LCD display continuously, even while the battery was bent at extreme angles. This could help develop gadgets in the future that can be rolled up for fabricating wearable devices seamlessly integrated into clothing.” it said.

Advanced microscopic tools

The scientists used advanced microscopic tools, including electron microscopes and spectroscopic techniques, to ensure the battery’s components were perfectly balanced for high performance.

“They rigorously tested the battery to confirm its efficiency, durability, and flexibility, ensuring it can stand up to real-world use. This innovation has promising implications for everyday applications,” the department added.

Potential developments could include flexible smartphones, safer electric vehicles, and wearable devices integrated into clothing.
