一种基于GQD/氢氧化钴复合材料的全固态柔性微型超级电容器
摘要：
本发明提供一种基于GQD/Co(OH)2复合材料的全固态柔性微型超级电容器，所述全固态柔性微型超级电容器的正极采用GQD/Co(OH)2复合材料制备而成，所述GQD/Co(OH)2复合材料按照包括如下步骤的方法制得：GQD(石墨烯量子点)粉体的水溶液、Co(NO3)2.6H2O、KCl与水混合均匀，以混合溶液为电解液，以纳米孔金线为工作电极，经恒流沉积获得GQD/Co(OH)2复合材料。本发明提供的基于GQD/Co(OH)2复合材料的全固态柔性微型超级电容器，具有良好的导电性和较高的能量密度，且其容量易于控制。
摘要（英）：

The invention provides an all-solid flexible micro super capacitor based on a GQD/Co(OH)2 composite material. The positive electrode of the all-solid flexible micro super capacitor is prepared from a GQD/Co(OH)2 composite material. The GQD/Co(OH)2 composite material is prepared according to the steps as follows: evenly mixing the aqueous solution of GQD (Graphene Quantum Dot) powder, Co(NO3)<2>.6H2O, KCl and water; and getting the GQD/Co(OH)2 composite material through galvanostatic deposition with the mixed solution as electrolyte and nanoporous gold wires as working electrodes. The all-solid flexible micro super capacitor based on a GQD/Co(OH)2 composite material provided by the invention has good conductivity and high energy density, and the capacity thereof is easy to control.
