Chinese researchers have created a new cathode material to increase the cycle-life of all-solid-state lithium batteries, potentially improving their viability for commercial applications.
The research was recently published in the journal Nature Energy.
The research team from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences, explained to Xinhua on Monday that all-solid-state lithium batteries using solid electrolytes are less likely to leak and burn than conventional liquid lithium-ion batteries, which are widely used in electric vehicles, mobile phones and computers.
According to Ju Jiangwei, a Ph.D. from QIBEBT and the corresponding author of the research, their new creation empowered all-solid-state lithium batteries with high conductivity, high specific discharge capacity, small volume change, high energy density, and long cycle life compared with previous solid lithium batteries.
This new homogeneous cathode material, which will enable solid lithium batteries to have higher safety and superior performance, has not yet been named.
Ju said the new material achieves over 1,000 times the electronic and ionic conductivity of traditional battery cathode materials. It can smoothly undergo charge and discharge cycles without conductive additives, which simplifies the battery preparation process and also improves the performance of the all-solid-state lithium battery.
All-solid-state lithium batteries have a huge market in the direction of power batteries, and their successful commercialization will provide strong momentum for the national new energy automobile industry and low-altitude economy.
