A composite with low crystallinity nickel manganate (NiMn2O4) on reduced graphene oxide (rGO) was synthesized by a solvothermal method. Velvet-like NiMn2O4 was deposited evenly on rGO nanosheets. The coverage of NiMn2O4 effectively prevents agglomeration between graphene flakes. The NiMn2O4/rGO composite has a large specific surface area and an excellent electrical conductivity due to the unique structure, and the specific capacitance is 1 675 F·g-1 at 1 A·g-1. The specific capacitance retention rate of NiMn2O4/rGO nanoflowers composite is 91% at 5 A·g-1 after 2 000 cycles.

采用溶剂热法制备了NiMn2O4/还原氧化石墨烯(NiMn2O4/rGO)复合材料,并对表面形貌、微观结构和电化学性能进行了表征和测试。结果表明:低结晶度的NiMn2O4以丝绒状均匀地沉积在rGO纳米片上,几乎没有rGO裸露在外,NiMn2O4纳米颗粒间的聚集现象消失;同时NiMn2O4的覆盖也有效地阻止了石墨烯层之间的团聚。由于其独特的结构,NiMn2O4/rGO具有较大的比表面积和良好的导电性。在1 A·g-1时的比电容是1 675 F·g-1。在5 A·g-1时,经过2 000个充放电循环后,NiMn2O4/rGO的比电容保持率为91%。

采用溶剂热法制备了NiMn2O4/还原氧化石墨烯(NiMn2O4/rGO)复合材料,并对表面形貌、微观结构和电化学性能进行了表征和测试。结果表明:低结晶度的NiMn2O4以丝绒状均匀地沉积在rGO纳米片上,几乎没有rGO裸露在外,NiMn2O4纳米颗粒间的聚集现象消失;同时NiMn2O4的覆盖也有效地阻止了石墨烯层之间的团聚。由于其独特的结构,NiMn2O4/rGO具有较大的比表面积和良好的导电性。在1 A·g-1时的比电容是1 675 F·g-1。在5 A·g-1时,经过2 000个充放电循环后,NiMn2O4/rGO的比电容保持率为91%。

A composite with low crystallinity nickel manganate (NiMn2O4) on reduced graphene oxide (rGO) was synthesized by a solvothermal method. Velvet-like NiMn2O4 was deposited evenly on rGO nanosheets. The coverage of NiMn2O4 effectively prevents agglomeration between graphene flakes. The NiMn2O4/rGO composite has a large specific surface area and an excellent electrical conductivity due to the unique structure, and the specific capacitance is 1 675 F·g-1 at 1 A·g-1. The specific capacitance retention rate of NiMn2O4/rGO nanoflowers composite is 91% at 5 A·g-1 after 2 000 cycles.
