Scheme of the new full sodium-ion battery, which combines an intercalation cathode and a conversion anode. The reported performance of the new Na-ion battery suggests that the sodium-ion system is a potentially promising power source for promoting the substantial use of low-cost energy storage systems in the near future, the team concluded.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

Researchers in South Korea have developed a novel high-energy cathode material, Na 1.5 F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). While high-energy Li-ion batteries (LIBs) are expected to contribute in part to the solution, the high cost and low stability prohibit wide application in this area, the researchers observe.
