Abstract:
In situ tracking of chemical phase transformation, mapping, and composition information of a battery with CuO as the anode was performed with quantitative analysis at sub-30 nm resolution with a 40 × 40 μm field of view using transmission X-ray microscopy combined with spectroscopy. A size-dependent and core-shell lithiation-delithiation mechanism was suggested for the electrochemical reaction.
