New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.<\/p>\n

\n

The University of Adelaide’s Professor Shizhang Qiao, Chair of Nanotechnology, and Director, Centre for Materials in Energy and Catalysis, at the School of Chemical Engineering, led a team which examined the sulphur reduction reaction (SRR) which is the pivotal process governing the charge-discharge rate of Li||S batteries.<\/p>\n

“We investigated various carbon-based transition metal electrocatalysts, including iron, cobalt, nickel, copper and zinc during the SRR,” said Professor Qiao who is an ARC Australian Laureate Fellow.<\/p>\n

“Reaction rates increased with higher polysulphide concentrations, as polysulphide serves as the reactive intermediates during SRR.”<\/p>\n

The team designed a nanocomposite electrocatalyst, comprising a carbon material and cobalt-zinc (CoZn) clusters.<\/p>\n

“When the electrocatalyst CoZn is used in lithium-sulphur batteries, the resulting battery achieves an exceptional power-to-weight ratio of 26120 W kgS<\/sub>-1<\/sup>,” said Professor Qiao.<\/p>\n

“Our research shows a significant advancement, enabling lithium-sulphur batteries to achieve full charge\/discharge in less than five minutes.”<\/p>\n

High-power lithium-sulphur batteries are used in various devices such as mobile phones, laptops, and electric vehicles.<\/p>\n

Current state-of-the-art lithium-sulphur batteries suffer from low charge-discharge rates, typically requiring several hours — typically from one to 10 hours — for a single full charge-discharge cycle.<\/p>\n

The team’s study, which is published in the journal Nature Nanotechnology<\/em>, is the first comprehensive approach to tackling the problem of slow charge\/discharge rates in lithium-sulphur batteries and has significant impact for scientists designing electrocatalyst materials and experts examining the reaction mechanisms of lithium-sulphur batteries.<\/p>\n

“Our breakthrough has the potential to revolutionise energy storage technologies and advance the development of high-performance battery systems for various applications,” said Professor Qiao.<\/p>\n

The high-power capabilities of these batteries make them well-suited for applications requiring rapid charging and discharging, offering enhanced performance and reliability for both consumer electronics and large-scale energy storage solutions in grid applications.<\/p>\n<\/div>\n
