IIT-Bombay Researchers Develop Eco-Friendly Lithium-Sulfur Batteries

Higher Noida: Shiv Nadar College in Higher Noida and Indian Institute of Know-how, Bombay (IIT-B) on Monday introduced that its researchers have created environment-friendly lithium-sulfur (Li-S) batteries.

The analysis will support the manufacturing of cost-effective, compact, energy-efficient, secure and environment-friendly Li-S batteries, providing a viable various to lithium-ion batteries used at current. The Li-S battery expertise has the potential to help multi-billion greenback industries, together with tech devices, drones, electrical automobiles (EV), and many others, that rely on such batteries.

The analysis reveals that this Li-S battery expertise — as soon as put into manufacturing — can be considerably cheaper and sustainable whereas providing as much as 3 times larger power density with intrinsic flame-retardant properties.

“The research focusses on the principles of Green Chemistry to find a solution that addresses the requirements of industries and the environment simultaneously,” examine lead researcher Bimlesh Lochab, Affiliate Professor of the Division of Chemistry at Shiv Nadar College, stated in a press release.

Based on the staff, the brand new battery expertise synthesizes a bio-based molecule able to commercial-scale manufacturing.

The analysis features a new kind of cathode for Li-S batteries which will help push the promising battery expertise to larger efficiency ranges. Using cardanol for sulfur-based constructions as an unconventional utility to create cathode supplies within the subsequent era Li-S battery expertise has exhibited enhanced capability retention (among the many highest cost capacities reported) and longer battery life in a considerably smaller battery unit.

The sulfur for the battery is sourced from industrial waste and cardanol from bio-renewable feed-stock that’s simply accessible, non-toxic and environment-friendly.

The analysis innovatively used eugenol (derived from clove oil) copolymer, which can be environmentally sustainable, halogen-free, flame-retardant and reduces the flamable propensities, making the battery remarkably secure to make use of.

“This breakthrough research by Dr. Lochab underlines the need for a clean energy solution at a time when our dependence on battery-operated devices has increased manifold,” stated Dr. Rupamanjari Ghosh, Vice-Chancellor, Shiv Nadar College.
