U Waterloo team identifies key reaction in sodium-air batteries; implications for improving Li-air

Green Car Congress

Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.

EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think!

Plug In India

In India, OLA Electric and Tata group have plans to make cells at a large scale. Video: EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think! The mining industry cannot keep up with the demand, so the alternative is to manufacture batteries based on sodium chemistry. Sodium is bigger and heavier than lithium cell.

Berkeley Lab leading investigation to quantify and characterize Salton Sea’s geothermal lithium resources

Green Car Congress

The hot brine that comes up from the subsurface as part of geothermal power production at the Salton Sea in California is a rich stew of minerals, including iron, magnesium, calcium, sodium, and lithium. Pat and his group will put that in a database. Credit: Jenny Nuss/Berkeley Lab). With nearly $1.2
