The invention discloses a nitrogen-sulfur co-doped porous graphene preparation equipment, the structure of which includes graphene battery equipment, support feet, coolers, calcining devices, heat pipes, heating machines, and the calcining device consists of a body, nitrogen-sulfur co-doping Porous graphene accumulator, shaping mold, push-pull rod, cylinder, and telescopic boom. The nitrogen-sulfur co-doped porous graphene raw material is put into the nitrogen-sulfur co-doped porous graphene accumulator, and the push-pull rod is driven by the cylinder. The shaping mold is pushed down, so that the shaping mold is inserted into the nitrogen-sulfur co-doped porous graphene accumulator, the nitrogen-sulfur co-doped porous graphene raw material is shaped by the model groove, and the nitrogen-sulfur co-doped porous graphene is shaped by the jack mechanism. Graphene raw materials are used to insert holes, increase the gap between nitrogen and sulfur co-doped porous graphene raw materials, improve the controllable amount of heteroatom doping and the number of mesopores, and make the doping sites and pore structure active sites for adsorbing sulfur More, while increasing the active sites of lithium storage and sodium storage.

AI Technical Summary

Problems solved by technology

In addition, doping sites and pore structures are also active sites for sulfur adsorption, which can be used as a carrier for sulfur in lithium-sulfur batteries, but the shape of nitrogen-sulfur co-doped porous graphene as a carrier is generally a block or cylindrical structure, so The shape of the doped site and pore structure is poor for the adsorption of sulfur active sites, and cannot improve the active sites for lithium storage and sodium storage.
