Monash University researchers report that they will soon commercialize what is presented as the most efficient lithium-sulphur (Li-S) battery available. Dr Mahdokht Shaibani from Monash University’s Department of Mechanical and Aerospace Engineering led an international research team to develop a high-capacity Li-S battery with better performance and less environmental impact than legacy lithium-ion batteries.
Using the same materials in standard lithium-ion batteries, researchers reconfigured the design of sulphur cathodes so they could accommodate higher stress loads without a drop in overall capacity or performance. Inspired by a bridging architecture first recorded in processing detergent powders in the 1970s, the team engineered a method that created bonds between particles to accommodate stress and deliver a high level of stability.
The research team comprises: Dr Mahdokht Shaibani, Dr Meysam Sharifzadeh Mirshekarloo, Dr M.C. Dilusha Cooray and Professor Mainak Majumder (Monash University); Dr Ruhani Singh, Dr Christopher Easton, Dr Anthony Hollenkamp (CSIRO) and Associate Professor Matthew Hill (CSIRO and Monash University); Nicolas Eshraghi (University of Liege); Dr Thomas Abendroth, Dr Susanne Dorfler, Dr Holger Althues and Professor Stefan Kaskel (Fraunhofer Institute for Material and Beam Technology).
