Determination of the mechanism and extent of surface degradation in Ni-based cathode materials after repeated electrochemical cycling

Determination of the mechanism and extent of surface degradation in Ni-based cathode materials after repeated electrochemical cycling

We take advantage of scanning transmission electron microscopy and electron energy loss spectroscopy to investigate the changes in near-surface electronic structure and quantify the degree of local degradation of Ni-based cathode materials with the layered structure (LiNi0.8Mn0.1Co0.1O2 and LiNi0.4M...
