NOVELTY - The present invention relates to a manufacturing method for adding graphene in positive and negative plates of a lithium battery, including the following steps: mixing a binding agent with an active solvent and stirring into a transparent liquid; stirring the transparent liquid with a positive electrode mixing material, a negative electrode mixing material and a graphene material respectively; forming a positive electrode coating material by uniformly mixing the transparent liquid with the positive electrode mixing material, forming a negative electrode coating material by uniformly mixing the transparent liquid with the negative electrode mixing material, and forming a graphene coating material after stirring the transparent liquid with the graphene material; and forming a positive plate of a lithium battery by coating a positive electrode metal layer with the graphene coating material and the positive electrode coating material, and forming a negative plate of the lithium battery by coating a negative electrode metal layer with the graphene coating material and the negative electrode coating material. The positive and negative plates of the lithium battery produced by the method can extend the cycle life of the finished battery, and increase the charge and discharge rate and safety.
