Abstract
Disclosed is a method for repairing a waste silicon-carbon material which relates to the technical field of secondary batteries. The method for repairing a waste silicon-carbon material includes the following steps: (1) pretreating the waste silicon-carbon material to obtain a powdery mixture; (2) mixing the powdery mixture obtained in step (1) with an metal-organic framework compound, and washing and drying the mixture to obtain a black powder; and (3) mixing the black powder obtained in step (2) with graphite, calcining the mixture in an acetylene atmosphere, and subjecting the calcined product to vapor deposition, cooling, washing and drying to obtain a silicon-carbon material.
