摘要：
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.
