Scientists discover simple trick that extends lithium battery life

Lithium-ion batteries are used in smartphones, laptops, electric cars, and stationary energy storage systems. Although their design has hardly changed in years, one key problem remains: the gradual aging of cells. That’s why lithium-ion batteries lose capacity over time.

A team of researchers at the University of Maryland (via NewScientist) have discovered a new solution that could extend the service life of lithium-ion batteries, all without changing internal cell structure or existing production processes.
