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.

V) between charge and discharge, and poor cyclability due to the drastic phase change of O 2 (gas) and O x− (condensed phase) at the cathode during battery operations. V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1 V in O x− (condensed phase) → O 2 (gas). V in O x− (condensed phase) → O 2 (gas).

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

The whole operation could take less than five minutes, pretty much the same amount of time many people spend filling their gas tanks at stations today. Most charge points available today take much longer to re-energize batteries than it does to fill a gas-powered cars tank. One of the main drawbacks to charge stations is speed.
