Brookhaven National Laboratory scientists have observed an unexpected phenomenon in lithium-ion batteries – the most common type of battery used to power cell phones and electric cars. As a model battery generated electric current, the scientists witnessed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing. This discovery, […]

A TU Graz scientist, Stefan Freunberger, investigated ageing processes in non-aqueous batteries and found an enzyme to lengthen battery life. It has long been known in biology that the excited oxygen molecule, singlet oxygen, is the main cause of aging in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide […]
