First Fully Rechargeable Carbon Dioxide Battery is Seven Times More Efficient Than Lithium Ion
Until now, however, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.
Researchers at the University of Illinois at Chicago are the first to show that lithium-carbon dioxide batteries can be designed to operate in a fully rechargeable manner, and they have successfully tested a lithium-carbon dioxide battery prototype running up to 500 consecutive cycles of charge/recharge processes.
Their findings are published in the journal Advanced Materials.
"Lithium-carbon dioxide batteries have been attractive for a long time, but in practice, we have been unable to get one that is truly efficient until now," said Amin Salehi-Khojin, associate professor of mechanical and industrial engineering at UIC's College of Engineering.
