Proton Battery Uses Cheap Carbon Instead of Lithium

A big challenge for the EV and renewable energy revolution is that the much-needed batteries are made from lithium, a relatively rare and pricey metal. Rather than focusing on other metals like magnesium, a team of scientists from RMIT University in Melbourne have figured it out to build rechargeable “proton” batteries from abundant carbon and water. If commercialized, the technology could allow for cheaper Powerwall-type home or grid storage to back up solar panels or windmills. . .
