Battery Research: Observing the Growth of Destructive Deposits in Real Time

Jülich, 3 March 2015 – With the help of a new process, Jülich scientists have made the first real-time observation of how porous layers form on a pure lithium anode during charging. The use of a lithium anode could considerably increase the energy density of lithium-ion batteries. The formation of destructive deposits is the biggest obstacle to the practical application of such anodes. For their investigations, the researchers used electron spin resonance (ESR) spectroscopy, a method related to the more widespread nuclear magnetic resonance.
