[1Da04] Local electrochemical measurement of all-solid-state batteries using c-AFM
We applied c-AFM to all-solid-state batteries to observe local electrochemical reaction. Battery samples were prepared using Li(Ni1/3Mn1/3Co1/3)O2 as the cathode active material and Li2S-P2S5 (LPS) as the solid electrolyte, and the cross-section of the cathode was observed by c-AFM. The result showed that charging current was observed at NMC/LPS interfaces and also grain boundaries inside MNC particles.
