(Phys.org)—When Ovadia Lev, Professor of Environmental Chemistry and Health at The Hebrew University of Jerusalem, and his research team developed a new coating technology a few years ago, they thought it was an interesting ...
(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
(PhysOrg.com) -- A breakthrough in components for next-generation batteries could come from special materials that transform their structure to perform better over time.
