协同组装3D Ni(OH)_(2)/石墨烯薄膜电性能研究

Study on Electrical Properties of Co-Assembled 3D Ni(OH)_(2)/Graphene Films

通过电化学剥离协同制备了3D Ni(OH)_(2)/石墨烯复合电极薄膜材料,高品质石墨烯均匀地生长在三维Ni(OH)_(2)表面,电化学性能测试表明,在2 m A/cm^(2)电流密度条件下,该电极薄膜具有优异的比电容(266 m F/cm^(2)),经过1万次的连续充放电循环测试仍然保留94.1%的容量性能。该方法为大规模生产新型高性能电极薄膜材料提供了一个简单的制备策略。

Three-dimensional nickel hydroxide[Ni(OH)_(2)]/graphene composite electrode films were pre-pared by electrochemical stripping.The high quality graphene was uniformly grown on the three-dimension-al Ni(OH)_(2) surface.The electrochemical performance test shows that the electrode film has an excellent spe-cific capacitance(266 mF/cm^(2))at the condition of 2 mA/cm^(2).After 10000 times of continuous charge-dis-charge cycle test,94.1%of the capacity performance is still retained.The method provides a simple prepa-ration strategy for mass production of novel high performance electrode thin film materials.
