"The research focusses on principles of green chemistry to find a solution that addresses requirements of industries and the environment, simultaneously. The capability of three times more energy density, coupled with being a significantly safer technology, holds the promise of accelerating the adoption of clean, battery-led energy across multiple domains," Bimlesh Lochab, Associate Professor at Shiv Nadar University, told PTI.
"For example, an electric car with a 400 km range using conventional Lithium-ion batteries can now quadruple its range to 1600 km on a single charge with this technology, while being compact in size and much safer to use than traditional Lithium-ion batteries. To put this in perspective, it could mean driving from Delhi to Mumbai on a single charge and still being left with power," she added.
Lochab's team has partnered with Sagar Mitra, IIT Bombay's Professor in the Department of Energy Science and Engineering, to use the research for the development of a Li-S battery prototype.
"From our laptops, mobile phones and smart watches to even electric cars depend on them. They are not efficient in terms of energy storage, they are heavy, expensive, extremely hard to recycle and also prone to combustion. The research innovatively used eugenol (derived from clove oil) copolymer, which is also environmentally sustainable, halogen-free, flame-retardant, and reduces the combustible propensities, making the battery remarkably safe to use," Mitra said.
The new battery technology synthesises a bio-based molecule, capable of commercial-scale production. The research includes a new type of cathode for Li-S batteries, which can help push the promising battery technology to higher performance levels.
"The use of cardanol for Sulfur-based structures as an unconventional application to create cathode materials in this next generation Li-S battery technology has exhibited enhanced capacity retention (among the highest charge capacities reported) and longer battery life in a significantly smaller battery unit. The Sulfur for the battery is sourced from industrial waste and cardanol is sourced from bio-renewable feed-stock that is easily available, non-toxic and environmentally friendly, Mitra added.
