Research Shows How Lithium Ion Batteries Can Get Better
January 17, 2018 | 1 Comment
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, […]
