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. to enlarge the interlayer lattice distance to accomodate the larger sodium ions.

UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

But a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt into the environment—whether it's for de-icing roads, fertilizing farmland or other purposes—releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and human health.

Debunking the Lithium "Mining" FUD

Plug In India

Team PluginIndia The Lithium mining FUD (Fear, Uncertainty, Doubt) created by some paid media organizations and random YouTube channels is so bad, that many people read headlines of such articles and assume that Lithium mining is the worst thing in the world and is worse than extracting and refining 10,000 liters of oil used by an average ICE car.
