A team of researchers at Australia’s Monash University have successfully fabricated lithium-sulfur (Li-S) batteries that are claimed to be capable of powering smartphones for five continuous days on a single charge. After developing prototype cells that were fabricated by Fraunhofer Institute for Material and Beam Technology in Germany, the researchers have filed for a patent on the manufacturing process.
Batteries that are made out of lithium-sulfur chemistry offer up to five times more energy per weight thereby holding a great deal of potential. The team was led by Dr. Mahdokht Shaibani from Monash University’s Department of Mechanical and Aerospace Engineering and involved two Indian scientists- Professor Mainak Majumder from Monash and Dr. Ruhani Singh from the Commonwealth Scientific and Industrial Research Organization (CSIRO). As per a report published by the institution, the new batteries use much of the same materials found in standard lithium-ion batteries, but with reconfigured sulfur cathodes to accommodate higher stress loads without a drop in overall capacity or performance.
Prof. Majumdar while talking about the new technology said, “Successful fabrication and implementation of Li-S batteries in cars and grids will capture a more significant part of the estimated $213 billion value chain of Australian lithium, and will revolutionize the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market”. According to him, “Our research team has received more than $2.5 million in funding from government and international industry partners to trial this battery technology in cars and grids from this year, which we’re most excited about”.
According to a report, some of the largest manufacturers of lithium batteries from around the world have shown interest in the technology.
