▎ 摘　　要

NOVELTY - The method involves mixing raw materials, where 0.5 to 0.8g of thioacetamide, 0.4 to 0.6g of nickel chloride and 0.6to 0.9g of tin chloride in the mixed solution of 55to 65ml of water/ethanol and stirs 25 to 35 min to obtain uniform solution. A framework material is added. The mixed solution is placed into the reaction kettle of polytetrafluoroethylene, and places a graphite substrate deposited with nitrogen/sulfur co-doped graphene pipe in a reaction vessel (3) in oven at specific temperature. High temperature is heated. The reaction kettle is put into oven heat preservation to obtain the graphene pipe with interface chemical bonding effect of nitrogen/sulfur co-doped tin sulfide/nickel sulfide composite super capacitor material positive electrode. USE - Method for preparing super capacitor composite positive electrode material. Uses include but are not limited to automobile, micro communication device, heavy machinery and aerospace. ADVANTAGE - The method enables showing the over-long circulation stability of new type composite electrode material; the electronic conduction can be carried out in time under the large current, more important is to ensure the structure stability of the composite electrode, so as to improve the over long cycle stability. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view of a nitrogen/sulfur co-doped graphene pipe and XRD pattern of tin sulfide/nickel sulfide composite material. 3Reaction vessel
