By improving a water-in-salt battery prototype, researchers believe they are well on their way to developing new high energy batteries. A team from the University of Maryland (UMD) and the U.S. Army Research Lab (ARL) have created a new type of chemical transformation of the cathode that yields, for the first time ever, a reversible…

Every year, many are quick to upgrade when new versions of the latest smartphones, tablets or other electronic devices come out, but what happens to all the batteries from the older, discarded devices? A Rice University research team believes that a deep eutectic solvent may be the answer to the growing battery-recycling problem. The solvent…
