The DrivenA team of Australian researchers have developed newbattery production methods that promise longer lasting batteries that could beused to boost the range of electric vehicles substantially.
In research published in the journal Science Advances, theMonash University led team applied techniques originally developed in theprocessing of detergent powders to discover a method of making more durablebatteries using lithium-sulfur materials.The researchers at Monash Universitythink that using the new method can greatly improve the stability of thelithium-sulfur batteries that promise greater energy storage densities, andcould unlock the production of higher performance and longer lasting batterysystems.Previous attempts to produce batteries using the lithium-sulfurmaterials, while offering greater energy storage densities, suffered from degradationin performance as the materials broke down under stress.
The Monash University research team has developed a newmethod to process the lithium-sulfur materials that provide a significantimprovement in the stability of the materials. The researchers predict the useof lithium-sulfur batteries could see a substantial increase in the range ofelectric vehicles, with the potential for new batteries to provide more than1000km of driving range.The battery technology could be used in a wide range ofapplications, including consumer products like phones.The research was led byMonash University’s Dr MahdokhtShaibani, who worked with an international research team on the development ofthe high capacity lithium-sulfur battery design.
The research team intends to test working examples of theinnovative battery design in electric vehicles and with solar energy systemsthroughout 2020.Leading battery manufacturers in China and Europe have alreadyexpressed interest in producing the new battery innovation at large-scale.
