CuO coating layers have attracted numerous attention due to its wide application in catalysis,batteries and other areas.However,the uncontrollable precipitation process of Cu2+has made it challenging to form uniform CuO nanoshells.In this study,uniform CuO nanoshells were prepared through a delicate design.Namely,the uniform Cu2+-poly(m-phenylenediamine)(Cu-PmPD)nanoshells were constructed firstly,and then the organic parts in the Cu-PmPD were removed while uniform CuO nanoshells formed in the controllable calcination process.Applying this method to high-voltage cathode materials,the CuO was successfully coated on the LiNi0.5Mn1.5O4,which greatly reduced the transition metal dissolution and improved the electrochemical performance in lithium-ion batteries.
