▎ 摘　　要

NOVELTY - Nitrogen-sulfur co-doped porous graphene preparation device comprises graphite battery device (1), a supporting leg (2), a cooler (3), a calcining device (4), a heat conducting pipe (5) and a heating machine. The graphene battery device is equipped with supporting foot at the bottom end and heating machine and calcination device on the top end of row from left to right. The heating machine and calcining device are connected with graphene battery device. The heating machine and the calcination device are connected through the heat-conducting pipe. The calcining device is installed under the cooler and the calcining device is comprises a machine body, a nitrogen-sulfur co-doped porous graphene material accumulator, a forming mold, a push rod, a cylinder and a telescopic boom. The machine body is provided with a nitrogen-sulfur co-doped porous graphene material accumulator. The machine body and cylinder is mechanically connected through the push rod. USE - Used as nitrogen-sulfur co-doped porous graphene preparation device. ADVANTAGE - The device: has more sulfur-active sites for doping sites and pore structures and; increases the active site of lithium storage and sodium storage. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the nitrogen-sulfur co-doped porous graphene preparation device.
