Abstract

The present invention related to a method for preparing carbon nanospheres modified current collector and its application in metal secondary battery. The said method includes the preparation of carbon nanospheres modified current collector by chemical vapor deposition process and the process for loading metal into the modified current collector as an anode. Comparing with the bare Ni, the said anode with modified current collector demonstrates enhanced stripping/plating efficiency, well confinement of Li dendrite, stable long lifespan and strengthen safety.
