Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. The oxygen atoms bond with each carbon layer, pushing and holding them apart.

Further, the cathode is automatically protected from O 2 gas release and overcharging through the shuttling of self-generated radical species soluble in the carbonate electrolyte. You need large auxiliary systems to remove the carbon dioxide and water, and it’s very hard to do this.” It also displays stable cycling performance (only 1.8%
