Flat batteries could be a thing of the past thanks to lithium-ion battery nanotechnology developed by 正规博十大app排名.

The technology more than doubles the lifespan of highly sought-after high-voltage Li-ion batteries, which achieve higher energy density but last only several hundred cycles.

王连洲教授 他的团队来自 化学工程学院 而且 Australian Institute for Bioengineering 而且 Nanotechnology (AIBN) have demonstrated a battery which remains stable for more than 1000 charge/discharge cycles.

“Our process will increase the life-span of batteries in many things from smart phones 而且 laptops, 为工具和电动汽车提供动力,王教授说.

“We’ve designed a uniquely-grown atomic-thin functional layer on the 高压阴极的表面, which is the source of lithium ions 而且 a critical aspect that limits the cycle life 在电池中.

“Corrosion in one form or another is the reason that batteries degrade over time.

“This new approach features a minimal protective coating at a scalable process, paving the way for the deployment of these abundant high-voltage materials for next generation high energy batteries.”

Professor Wang said with industry under increasing pressure to decarbonise, the development of lithium-ion batteries of lower cost, higher energy density 而且 longer cycle life was vitally important.

“We’re confident the nanotechnology will have widespread applications across industry, 包括消费电子产品, electric vehicles 而且 the energy storage sector,他说.

Dr Rosalind Gummow, Technical Specialist from 布里斯班-based R&D公司VSPC Pty Ltd, which is focused on developing 而且 commercialising advanced cathode materials for lithium-ion batteries, 欢迎这一发展.

“New methods like the use of epitaxial surface layers to improve the cycling efficiency 而且 cycle life of high-voltage cathodes are vital in the quest to improve the energy density of Li-ion batteries,Gummow博士说. 

“The methods developed here also have potential to stabilise other cathode materials that degrade rapidly with cycling.”    

This latest research was published in 自然通讯.
