NOVELTY - Preparing graphene/indium phosphide composite electrode material, involves adding cationic surfactant hexadecyl trimethyl ammonium bromide to graphene oxide solution in alkaline environment, treating ultrasonically and adding 0.25-0.75 mmole indium salt and stirring uniformly. The mixture is placed at reaction kettle and 0.2-0.6 gram phosphorus is added and hydro-thermal reaction is carried out for 8-16 hours at 120-180 degrees C. The mixture is cooled, washed and dried until the amount of the oxidized graphite alkene is 2.5-10 mmole. USE - Method for Preparing graphene/indium phosphide composite electrode material (claimed). ADVANTAGE - The method enables to prepare graphene/indium phosphide composite electrode material, is simple, safe, the prepared composite material has good electrical performance, and the current density of the material is 50 milliampere hour/gram, after 100 cycles, still can keep the 800 milliampere hour/gram specific capacity.
