摘　　要：Cobalt selenide(CoSe_(2))has gained extensive interests due to its high redox reactivity and theoretical capacity.However,its substantial volumetric change during reaction leads to structural instability and consequently inferior cycling performance.In this study,a Co-zeolitic imidazolate framework was synthesized as the precursor via the solvotihermal method and then subjected to a selenizationtreatment to transform into CoSe_(2)nanoparticles.

关 键 词：capacity. SKELETON CONFINED
