The high voltage application of the LiNi0.5Co0.2Mn0.3O2 cathode is still hindered by its unstable surficial structure and poor capacity retention. Surface coating has been proved to be an effective strategy to deal with these problems. However, previous multistep surface coating approaches greatly complicate the synthesis procedure. In this work, a simple and large-scale solid-state approach is developed to prepare lanthanum-based oxides co-coated LiNi0.5Co0.2Mn0.3O2 cathode materials. Electrochemical tests indicate that the co-coated samples e...
