Researchers Track Nanoscale Structural Changes Degrading Battery Performance

Researchers Track Nanoscale Structural Changes Degrading Battery Performance

Batteries do not age gracefully. The lithium ions that power portable electronics cause lingering structural damage with each cycle of charge and discharge, making devices from smartphones to tablets tick toward zero faster and faster over time. To stop or slow this steady degradation, scientists must track and tweak the imperfect chemistry of lithium-ion batteries with nanoscale precision. [More]
