▎ 摘  要

NOVELTY - The present disclosure provides a method for manufacturing a negative electrode. The method includes following steps. A cavitation process is performed on a raw material of carbon in a liquid phase exfoliation to form a graphene. The graphene and a liquid nitrogen source are added to a container and then performing a nitrogen-doping through hydrothermal method to form a nitrogen-doped graphene.
