For consumers considering an electric vehicle (EV), long charge times, some up to 12 hours, can be a deal-breaker. But researchers may have discovered a way to reduce the charging time of the lithium-ion batteries used in EVs to less than 15 minutes. Led by Ravi Prasher, adjunct professor of mechanical engineering at UC Berkeley …
Keep it cool
Salt has been long used to prevent ice from forming on roads by lowering the freezing point of water. Now, mechanical engineering Ph.D. student Drew Lilley and adjunct professor Ravi Prasher, working with Berkeley Lab researchers, have used this same concept to develop a new method of heating and cooling. Known as ionocaloric cooling, the technique has the potential …
Berkeley Lab Scientists Develop a Cool New Method of Refrigeration
Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named “ionocaloric cooling,” is described in a paper published Dec. 23 in …
