Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Wen heats the expanded, oxidized graphite to high temperatures and floods it with argon gas, causing it to decompose. In this process, oxygen bonded to carbon breaks away in the form of either carbon monoxide (CO) or carbon dioxide (CO 2 ) gas, which is caught up and removed by the argon gas flow.
