Contrary to these reports, recent studies questioned the compatibility of LIC and LPSCl in Ni-rich-based cathode cells in general. For example, Koc et al found that at a cell potential ≥3.65 vs Li/In the decomposition of LIC takes place, as well as a quadruple increase in the interfacial resistance between LIC with LPSCl in a bilayer configuration at 80 °C, indicating not only electrochemical but also chemical instability . This chemical incompatibility between LIC with LPSCl has been proposed to translating into the formation of a passivation interlayer, which leads to degraded electrochemical performance of up to 50 % upon cycling . This chemical instability has been throughout studied subsequently by Rosenbach et al using FIB-SEM combined with TOF-SIMS.
