In this study, LiNi0.5Mn1.5O4was prepared by solid-state synthesis method and MgCO3,Al2O3,SiO2,TiO2were dry-coatedon the surface of LiNi0.5Mn1.5O4. The structure and geometry of pure-LNMO and coated-LNMO were characterized byXRD, SEM, SEM–EDS. Dry coating method was applied and various coating materials were evaluated in terms of thestability study at room/high temperature and electrochemical property. The results of XRD and SEM–EDS demonstratedthat MgCO3,Al2O3,SiO2,TiO2were coated on the LiNi0.5Mn1.5O4surface without any structural changes. Compared withpure-LNMO, the coated-LNMO shows significant decrease in side-reaction with electrolyte solution at the first cycle of theelectrochemical test. In addition, coated-LNMO displays prominent thermal-stability at 25 °C and 55 °C and high c-rate,compared with pure-LNMO. Especially the coating layer of SiO2inhibits the side-reaction with electrolyte solution inducedby initial moisture formation. Therefore, the stability of capacity is significantly improved at the temperature of 55 °C andhigh c-rate, which are same results with those obtained by the electrochemical impedance spectroscopy results. This studyhas employed solid-state synthesis and dry coating method for the evaluation of various coated-LNMO materials and demonstratedthe possibility to develop new high energy density electrode materials by surface modification.
