摘　　要：CuO coating layers have attracted numerous attention due to its wide application in catalysis,batteries and other areas.However,the uncontrollable precipitation process of Cu^(2+)has made it challenging to form uniform CuO nanoshells.In this study,uniform CuO nanoshells were prepared through a delicate design.Namely,the uniform Cu^(2+)-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 LiNi_(0.5)Mn_(1.5)O_(4),which greatly reduced the transition metal dissolution and improved the electrochemical performance in lithiumion batteries.
