摘　　要：通过电化学剥离制备石墨烯,同时协同组装制备了3D MnO_(2)/石墨烯电极薄膜材料,电化学性能测试表明,它具有较高的电容量、倍率性能和较好的循环稳定性,在1 A/g的电流密度下具有607 F/g的较高电容量,在循环10 000圈后仍保持94.1%的容量值,未来可以应用到新型电极材料等领域。Graphene was prepared by electrochemical stripping,and 3D MnO_(2)/graphene electrode film mate-rial was prepared by co-assembly.The electrochemical performance test shows that it has high capacitance,rate performance and good cycle stability,and has a high capacitance of 607 F/g at a current density of 1 A/g.After 10000 cycles,it still maintains 94.1%capacity value.In the future,it can be applied to new electrode materials and other fields.
