NOVELTY - A lithium ion secondary battery electrode material includes: a multilayer graphene produced by using a mechanical process to pulverize wormlike graphite solution and then convert it into a multi-layer graphene solution; an electrode material powder; wherein, mixing and drying the electrode material powder and the multilayer graphene solution may produce the multilayer graphene adhered on the electrode material powder to form the lithium ion secondary battery electrode material. Thereby, a lithium ion secondary battery electrode material can be prepared quickly and effectively.
