Construction of uniform CuO nanoshells and its application in high-voltage cathode materials
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.
