The application of Lithium-ion batteries (LIBs) in portable electronics and electric vehicles (EVs) has increased in the past decade. Extended commercialization of LIBs for advanced applications requires the development of high-performance electrode materials. LiNi0.5Mn1.5O4 (Lithium Nickel Manganese Oxide referred to as LNMO) has attracted much attention as a cathode material due to its high voltage and energy density, lower cost, and environmental friendliness. However, LNMO cathodes are currently suffering from poor cyclability and capacity degradation at elevated temperatures. Many strategies have been suggested in the literature to address the challenges associated with numerous families of cathode materials. Among those, surface modification techniques like surface coatings have proven to be promising. Surface coatings have a good effect on the electrochemical performance of LNMO, as these result in increasing electronic and ionic conductivity, fast ions mobility and high diffusivity. Towards this direction, a systematic review of research progress carried out in the area of coated LNMO has been summarized. More precisely, the impact of numerous coating materials in improving cyclability and capacity retention at elevated temperatures of LNMO has been discussed along with a variety of coating synthesis technologies.
