Monitoring metallic sub-micrometric lithium structures in Li-ion batteries by in situ electron paramagnetic resonance correlated spectroscopy and imaging

Abstract

Monitoring the nucleation of dendrites in Li-ion batteries during cell cycling is important for the development of new electrochemical materials. Here, the authors use the spectral-spatial mode in electron paramagnetic resonance imaging to visualize the spatial distribution of metallic sub-micrometric lithium structures.
