Smoothing Over Rough Edges in Batteries

Battery performance suffers over time, like when a phone needs to be charged more frequently after years of use. A thin film that forms on the metal anode when the battery is charging and discharging plays a part in that issue. This film has benefits, but its roughness gradually wears the battery down. Researchers have discovered a temporary version of this film that appears at rapid discharge speeds and dissolves back into the battery when the process finishes. Read on to learn more.
