Metal-air batteries have become one of the most potential power sources for electric vehicles due to their high energy density, environmental friendliness and low cost. Tsing-hua University and the University of Liverpool in the United Kingdom have collaborated in research and discovered a new type of charge storage mechanism, which breaks through the limitation that calcium-air batteries cannot be recharged and discharged in the past. Due to the extremely high accumulation of calcium on the surface, the oxygen in the air can also be obtained infinitely. The results of this research will take a big step towards the creation of sustainable battery technology.

This research has been published in the latest issue of the top international journal "Chemical Science" . The first author is Yi-ting Lu , a PhD student of Tsing-hua and Liverpool, co-directed by Professor Laurence Hardwick of the Department of Chemistry of the University of Liverpool and Professor Qi-zhang Hu of the Department of Chemistry of Tsing-hua University, and another postdoctoral researcher of Liverpool, Alex Neale. Also participate in research.
