Researchers in Australia have developed a new battery technology that could significantly cut electric vehicle (EV) charging times, a study has revealed, El.kz cites Xinhua.
Researchers at Australia's Adelaide University created lithium-ion pouch battery cells to record a charge of more than 85 percent after six minutes, while maintaining an energy density of about 240 watt-hours per kilogram, said a university statement released Thursday.
Fast charging is key to EV adoption, but current high-capacity batteries degrade quickly and generate excess heat, raising safety risks, said Professor Qiao Shizhang from Adelaide University, who led the study.
The breakthrough, published in Nature Energy, uses interfacial anion-reduction catalysis to regulate reactions at the interface, enabling fast charging without sacrificing ionic conductivity, Qiao said, adding it forms a stable protective layer critical for performance and long-term stability.
The discovery offers a new approach to practical fast-charging lithium-ion batteries and could enable EVs to charge in minutes without sacrificing lifespan or energy density, he said.
"Our test cell exhibited excellent performance, achieving about 76 percent capacity retention after 500, six-minute cycles," Qiao said, adding the cells also exhibited excellent stability at 10 minutes of charging.
