Monash University Researchers Develop Ultra-Efficient Li-S Batteries

Research conducted at Monash University has led to the development of highly efficient batteries. The batteries are a combination of lithium and sulphur, and are due to revolutionize several commercial applications.  The lithium-sulphur batteries are four times more efficient than the models available in the market. With the capacity to power Australia and other regional pockets, these batteries could emerge as a ground-breaking technology.

 It is expected these batteries could support power for a smartphone for five days without need to be charged. Moreover, equipping these batteries in electric vehicles could optimize their single-charge run. The research was led by Dr. Mahdokht Shaibani from the department of Mechanical and Aerospace Engineering at Monash. Other researchers included Assistant Professor Matthew Hill and Professor Mainak Majumder.

 Addressing Problem of Power Optimization

 The researchers assert that the lithium-sulphur batteries are better in performance and environmental-friendliness. Furthermore, the ultra-high capacity of the batteries could help in addressing problems of optimal power in multiple devices. The researchers collaborated with Fraunhofer Institute for Material and Beam Technology for fabricating prototype cells. Moreover, they also received approved patents for their manufacturing processes. Science Advances journal published the findings of the research on 03rd January, 2020. The development displays potential to transform manufacturing of cars, phones, and grids, stated one of the researchers. Furthermore, this could give an impetus to manufacturing technologies in Australia.

 Support from Key Entities

 Li-S batteries are expected to account for a significant share of the $213 bn value chain estimated for Australian lithium. Moreover, the Australian vehicle market could also grow through the development of lithium-sulphur batteries. The research team revealed that they have received funding worth $2.5 million from governments and industry partners. Chinese and European manufacturers of lithium batteries have also shown interest in upscaling production of these batteries.
