The present application provides a lithium carbon composite belt and a preparation method therefor. The lithium carbon composite belt comprises a substrate, a metal lithium transition layer on each side of the substrate, and a lithium carbon composite material layer on an outer layer of the metal lithium transition layer, wherein a mass fraction of carbon in the lithium carbon composite material layer is in a range from 5% to 90%. The substrate layer of the lithium carbon composite belt provides high tensile performance for the lithium carbon composite belt, which is suitable for large scale industrial production. The metal lithium transition layer makes the substrate layer tightly bound with the lithium carbon composite material layer, avoiding the problem of forming bumps during the production of the lithium carbon composite belt. The presence of the metal lithium transition layer can effectively reduce the internal resistance of the lithium carbon composite belt. The lithium in the transition layer is active lithium, and thus can also participate in the battery cycling process, so as to compensate the consumption of the metal lithium in the lithium carbon layer. The lithium carbon composite material layer contains a carbon skeleton, which can not only provide a reserved space for metal lithium deposition, inhibiting the volume change of the metal lithium during the cycling, but also effectively reduce local current density on an electrode, preventing the formation of lithi
