Batteries lose capacity over time, which is why older cellphones run out of power more quickly. This common phenomenon, however, is not completely understood.
Now, an international team of researchers, led by an engineer at the University of Colorado Boulder, has revealed the underlying mechanism behind such battery degradation. Their discovery could help scientists to develop better batteries, which would allow electric vehicles to run farther and last longer, while also advancing energy storage technologies that would accelerate the transition to clean energy.
The findings were published September 12 in the journal Science.
