Charging lithium-ion batteries too quickly can permanently reduce the battery capacity. Portions of the energy storage structure are thereby destroyed and deactivated. These structural changes have been visualized for the first time. The fluorescence studies show that even after only a few charging cycles, damage to the inner structure of the battery material is clearly evident, damage which takes longer to arise during slower charging.
