State-of-Charge Mapping in Batteries. Scientific Achievement We can now visualize the motion of lithium ions for a significant number of battery particles at the nanoscale. Significance and Impact
State-of-charge mapping (left) and morphology (right) via STXM and TEM, respectively, of regions in the LFP composite electrode (A) 26 μm, (B) 18 μm, and (C) 6 μm from the Al current collector. Colors indicate the local state of charge, and brightness gives the LFP thickness. Outlined in white are particles in which two phases coexist.
