A process for producing solid nanocomposite particles for lithium metal or lithium ion battery electrode applications is provided. In one preferred embodiment, the process comprises: (A) Preparing an electrode active material in a form of fine particles, rods, wires, fibers, or tubes with a dimension smaller than 1 μm; (B) Preparing separated or isolated nano graphene platelets with a thickness less than 50 nm; (C) Dispersing the nano graphene platelets and the electrode active material in a precursor fluid medium to form a suspension wherein the fluid medium contains a precursor matrix material dispersed or dissolved therein; and (D) Converting the suspension to the solid nanocomposite particles, wherein the precursor matrix material is converted into a protective matrix material reinforced by the nano graphene platelets and the electrode active material is substantially dispersed in the protective matrix material. For a lithium ion battery anode application, the matrix material is preferably amorphous carbon, polymeric carbon, or meso-phase carbon. Such solid nanocomposite particles provide a high anode capacity and good cycling stability. For a cathode application, the resulting lithium metal or lithium ion battery exhibits an exceptionally high cycle life.

A sole structure with complex waterproof and gas-permeable material and a manufacturing method thereof. A plane blank having a through with a pattern of an array is provided. At least one waterproof and gas-permeable film is combined with the plane blank to cover the through hole. The plane blank with the film is located in a predetermined position inside a sole mold. Then a molten plastic material is filled into the mold to associate the plane blank and the film with the plastic material to form an integral large substrate of the sole. The sole provides waterproof and gas-permeable effect to prevent water from tarrying between the large substrate and middle substrate.
