快速充电的锂硫电池即将问世

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.
新研究表明，下一代锂硫（Li||S）电池的充电时间可能从目前的数小时缩短至不足五分钟。

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.
阿德莱德大学化学工程学院纳米技术主席兼能源与催化材料中心主任乔世璋教授领导团队研究了硫还原反应（SRR），该反应是决定Li||S电池充放电速率的关键过程。

"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.
"我们研究了多种碳基过渡金属电催化剂，包括铁、钴、镍、铜和锌在SRR过程中的表现，"ARC澳大利亚桂冠教授Qiao表示。

"Reaction rates increased with higher polysulphide concentrations, as polysulphide serves as the reactive intermediates during SRR."
随着多硫化物浓度的增加，反应速率也随之提高，因为多硫化物在SRR过程中作为反应中间体发挥作用。

The team designed a nanocomposite electrocatalyst, comprising a carbon material and cobalt-zinc (CoZn) clusters.
该团队设计了一种纳米复合电催化剂，由一种碳材料和钴锌（CoZn）簇组成。

"When the electrocatalyst CoZn is used in lithium-sulphur batteries, the resulting battery achieves an exceptional power-to-weight ratio of 26120 W kg_S^-1," said Professor Qiao.
乔教授表示："当电催化剂CoZn用于锂硫电池时，电池的功率重量比可达到26120 W kg，性能卓越。"

"Our research shows a significant advancement, enabling lithium-sulphur batteries to achieve full charge/discharge in less than five minutes."
我们的研究表明，锂硫电池取得了重大进展，可在不到五分钟内完成充放电。

High-power lithium-sulphur batteries are used in various devices such as mobile phones, laptops, and electric vehicles.
高功率锂硫电池用于手机、笔记本电脑和电动汽车等各种设备。

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.
目前最先进的锂硫电池充放电速率较低，通常需要数小时——通常为1到10小时——才能完成一个完整的充放电周期。

The team's study, which is published in the journal Nature Nanotechnology, 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.
该团队发表在《Nature Nanotechnology》期刊上的研究，是首个全面解决锂硫电池充放电速率缓慢问题的方案，对设计电催化剂材料的科学家和研究锂硫电池反应机制的专家具有重大影响。

"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.
乔教授表示："我们的突破性成果有望彻底改变储能技术，并推动面向多种应用场景的高性能电池系统开发。"

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.
这些电池的高功率能力使其非常适合需要快速充放电的应用，为消费电子产品以及电网应用中的大规模储能解决方案提供了更高的性能和可靠性。
