具有不同暴露面的小平面晶体吸引了广泛的应用研究。在这里,我们报告了一个简单的水热和热分解过程中,成功地开发了生长3D NiCo2O4微球与径向链状NiCo2O4纳米线与不同的暴露的晶面构造。当用作超级电容器的电极材料时,链状NiCo2O4纳米线在超级电容器中表现出优异的电化学性能,具有高比电容(在2 A g−1时为1284 F g− 1)、良好的倍率性能和优异的循环稳定性(在3000次循环后仅损失2.5%)。原位电性能测试结果表明,不同晶面暴露的链状纳米线具有良好的导电性,表明电子导电性对超级电容器电极材料的性能起着至关重要的作用。因此,具有不同暴露晶面的高电子电导率链状NiCo2O4纳米线可以形成下一代超级电容器的竞争电极材料。
Faceted crystals with different exposed planes have attracted intensive investigations for applications. Herein, we report a facile hydrothermal and thermal decomposition process which is successfully developed to grow 3D NiCo2O4 micro-spheres constructed with radial chain-like NiCo2O4 nanowires with different exposed crystal planes. When applied as electrode materials for supercapacitors, chain-like NiCo2O4 nanowires exhibit excellent electrochemical performances in supercapacitors with high specific capacitance (1284 F g−1 at 2 A g−1), good rate capability, and excellent cycling stability (only 2.5% loss after 3000 cycles). In situ electrical properties clearly illustrated that the chain-like nanowires with different exposed crystal planes exhibit excellent electronic conductivity, which shows that the electronic conductivity plays an essential role for electrode materials in supercapacitors. So, high electronic conductivity chain-like NiCo2O4 nanowires with different exposed crystal planes can form a competitive electrode material for next generation supercapacitors.
