NOVELTY - A method for manufacturing a multi-layered long-cycle silicon-carbon negative electrode material, comprising taking a pure silicon and a first masterbatch, the first masterbatch is composed of a solvent and a dispersant; the dispersant is composed of a polymer proppant, Small molecule anchoring agent and thickening agent; then pure silicon and the first masterbatch are mixed to form a first mixture and then ground to form a first grinding body; then a graphene and another first masterbatch are taken Glue, mix the two and grind to form a second grinding body; then mix the first grinding body and the second grinding body to form a second mixture, and then carry out planetary mixing, emulsification homogenization and deaeration planetary mixing Then the carbon nanotubes (CNT) and a second masterbatch are mixed and placed in a blade stirring tank to stir, and then placed in an emulsifier to stir to form a third mixture; the composition of the second masterbatch is a solvent and a coating agent; then the treated second mixture and the third mixture are planetary mixed to form a fourth mixture; and finally the fourth mixture is spray-dried to form a The silicon-carbon composite structure hybrid in this case.
