A new lithium-sulfur battery for a range of 1000 km is announcedThe Monash University of Australia has announced that its researchers have developed "the world's most efficient lithium-sulphur battery". In more specific terms, their product will enable an electric vehicle to drive more than 1000 km on a single charge. Smaller-size batteries are able to power a smartphone for five continuous days. Prototype cells have already been produced in Germany and further testing for EV batteries and solar grids will be carried out in Australia this year.

The Monash University is one step closer to commercializing its lithium-sulphur (Li-S) battery "which could outperform current market leaders by more than four times." Some of the largest lithium batteries producers in China and Europe have already expressed their interest in upscaling production.

The researchers have been using the same materials in standard lithium-ion batteries but changed the sulphur cathodes design in such a way as the cathodes are able to accommodate higher stress loads avoiding a decrease in overall capacity or performance. This enhanced level of battery stability has been achieved by a method of creating bonds between particles that employs a unique bridging architecture in processing detergent powders from the 1970s.

This new lithium-sulfur battery delivers attractive performance, is cheap to manufacture, enjoys an abundant supply of material, and has a reduced environmental footprint. Professor Mainak Majumder said this development was a breakthrough for Australian industry and could transform the way phones, cars, computers and solar grids are manufactured in the future. "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 revolutionise the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market," Professor Majumder said.Source
