Abstract
Monodisperse microspheres are arranged in macropores of a substrate to form a photonic crystal structure; with the photonic crystal as a template, ordered microporous carbon is synthesized in gaps of the template, and then the photonic crystal template is removed to obtain a three-dimensional ordered hierarchical porous carbon photonic crystal, and thus a large-area thick-film controllable textured photonic crystal is formed and is composited with element sulphur to obtain a sulphur cathode, and the sulphur cathode and metal lithium serving as a counter electrode are assembled into a lithium-sulphur battery. According to the invention, the controllable thick film with an electrode thickness of 10 μm to 650 μm can be achieved by changing the thickness of the substrate and the concentration of a suspension liquid. In the meanwhile, large-area preparation with an electrode area of 0.1 cm sup.2 to 400 cm sup.2 can be achieved by changing the area of the substrate.
