Özet

Transition metal selenides (TMSes) face challenges such as low electronic conductivity, significant volume expansion, and particle agglomeration during charge and discharge processes, limiting their practical application in batteries. A promising solution involves integrating a carbon matrix into TMS-based anodes, which can enhance conductivity and mitigate volume stress. In this study, we synthesized novel Cu₂Se/ZnSe@NPC and Cu₂Se@NPC nanoparticles, embedded in a nitrogen-doped porous carbon (NPC) network using zeolitic imidazolate framework-11 (ZIF-11) as a template, for the first time as anode materials in lithium-ion (LIBs) and sodium-ion batteries (SIBs). The Cu₂Se/ZnSe@NPC and Cu₂Se@NPC nanoparticles demonstrate impressive initial capacities of 762 and 712 mAh g⁻1 at 0.1 A g⁻1, respectively, and deliver specific capacities of 401 and 358 mAh g⁻1 at 0.3 A g⁻1 for lithium-ion half-cell batteries. For sodium-ion half-cell batteries, these materials achieve satisfactory initial capacities of 455 and 349 mAh g⁻1 at 0.1 A g⁻1, and exhibit exceptional cycling stability with capacities of 223 and 204 mAh g⁻1 after 1000 cycles at 2 A g⁻1, respectively.
