▎ 摘　　要

NOVELTY - A zinc ion doped magnetite hollow sphere-graphene electrode material preparing method involves weighing a graphene oxide powder, adding the graphene oxide powder to an ethylene glycol solvent and sonicating to complete dispersion to obtain mixed solution A. Iron(III) chloride hexahydrate is added to the graphene oxide-glycol mixed solution A and magnetically stirred until completely dissolved, added with a zinc chloride and magnetically stirred until completely dissolved to obtain a mixed solution B. An ethanolamine reagent is added to the mixed solution B and the obtained mixed solution is placed in a 50 mL reaction kettle and reacted at a high temperature. The powder is separated by a strong magnet and washed several times with deionized water and absolute ethanol, after the reactor is naturally cooled to room temperature, and finally dried under vacuum at 50-70 degrees C to obtain the finished product. USE - Method for preparing zinc ion doped magnetite hollow sphere-graphene electrode material for use in super capacitors. ADVANTAGE - The method enables preparing zinc ion doped magnetite hollow sphere-graphene electrode material with high safety and excellent electrochemical energy storage property, in simple and easy manner.
