首次合成了不同Ni、Co比例的双金属Ni-Co硒化物，并将其用作高功率储能电极材料。由于Ni和Co之间的协同效应，双金属Ni-Co硒化物，特别是Ni0.67Co0.33Se，比单金属Ni或Co硒化物表现出更高的比容量和改进的倍率性能以及优异的循环稳定性。
For the first time, bimetallic Ni-Co selenides with different Ni and Co ratios have been synthesized and used as electrodematerials for high-power energy storage. Owing to the synergistic effect between Ni and Co, bimetallic Ni-Co selenides, especially for Ni0.67Co0.33Se, show higher specific capacity and improved rate capability combined with excellent cycling stability than the monometallic Ni or Co selenide.
