referring to fig. 1, the graphite material of the first graphite sheet 11 and the second graphite sheet 12 of the present embodiment is made of graphene, wherein the ratio of graphene (graphene): the carbon material is a two-dimensional carbon material and is a general name of single-layer graphene, double-layer graphene and multi-layer graphene;
Single layer Graphene (Graphene): refers to a two-dimensional carbon material composed of a layer of carbon atoms which are periodically and closely packed in a benzene ring structure (i.e. a hexagonal honeycomb structure);
Bilayer graphene (Bilayer or double-layer graphene): the two-dimensional carbon material is formed by stacking two layers of carbon atoms which are periodically and closely stacked in a benzene ring structure (namely a hexagonal honeycomb structure) in different stacking modes (including AB stacking, AA stacking and the like);
Few-layer graphene (Few-layer): the carbon material is a two-dimensional carbon material formed by stacking 3-10 layers of carbon atoms which are periodically and closely stacked in a benzene ring structure (namely a hexagonal honeycomb structure) in different stacking modes (including ABC stacking, ABA stacking and the like);
