Why do lithium batteries degrade over time? US Researchers have collaborated to discover more about the mechanisms behind this degradation, with promises of improved battery life. Lithium batteries are used today to power many portable electronics devices. But lithium-ion batteries suffer nano-scale structural damage with each charge and discharge cycle. In two recent Nature Communications papers, scientists from several U.S.
