| 摘要: 首先采用乙醇胺-氢氧化钾体系，实现了在泡沫镍表面原位生长NiTe活性物质层，随后以此为基体，通过复合Co9S8活性物质，构建出具有“三明治”结构、高容量、高循环稳定性的Co9S8/NiTe/Ni复合电极材料。该电极不仅在2 A·g-1电流密度下表现出1 890 F·g-1的比电容，而且在大电流密度下依然表现出优异的稳定性。 | |

| Abstract: The NiTe/Ni electrode was obtained in the mixed solvent of ethanolamine and KOH. Subsequently, the Co9S8/NiTe/Ni composite electrode with a sandwich-like structure was fabricated after the hydrothermal treatment in the aqueous solution of Co(NO3)2 and thiourea. The electrode not only exhibited an ultra-high specific capacity of 1 890 F·g-1 at a current density of 2 A·g-1, but also exhibited excellent cyclic stabilities at high current densities. | |
