Indian Researchers Develop Sustainable Li-S Batteries

Researchers at Shiv Nadar University in partnership with the Indian Institute of Technology-Bombay have developed a lithium-sulfur (Li-S) battery technology.
The research will aid the production of cost-effective, compact, energy-efficient, safe and environment-friendly Li-S batteries, offering a viable alternative to lithium-ion batteries commonly used at present.
The batteries incorporate petroleum industry by-products such as sulfur and have the potential to power tech gadgets, drones, electric vehicles, etc.
It also uses agro-waste elements and copolymers such as cardanol (a by-product of cashew nut processing) and eugenol (clove oil) as cathodic materials.
The production technology can help produce Li-S batteries in a more sustainable and much cheaper way offering up to three times higher energy density with intrinsic flame-retardant properties.
The capability of 3x energy density, coupled with being a significantly safer technology, holds the promise of accelerating the adoption of clean, battery-led energy across multiple domains.
