摘　　要：金属锌具有良好的成本效益、安全性和环境友好性,被普遍认为是构建各种水性电池的首选材料。然而,锌电极在水溶液中易发生副反应和枝晶生长现象,限制了锌离子电池在大规模储能方面的应用。硒化锌(ZnSe)具有优异的导电特性、良好的充放电性能、较低的电极电位,可以有效地抑制锌负极表面的腐蚀反应、枝晶生长和析氢反应。本文采用电沉积方法在锌负极上构筑ZnSe界面层,通过Zn@ZnSe负极材料组装全电池,考察电池的电化学性能。结果表明,具有ZnSe界面层的锌离子电池经过5000次充放电循环后仍具有良好的稳定性。Metal zinc is widely recognized as the preferred material for constructing various aqueous batteries due to its cost-effectiveness,safety and environmental friendliness.However,zinc electrode is prone to side reactions and dendrite growth in aqueous solutions,which restricts the application of zinc-ion batteries in large-scale energy storage.Zinc selenide(ZnSe)has excellent electrical conductivity,good charge-discharge performance and low electrode potential,which can effectively inhibit corrosion reactions,dendrite growth and hydrogen evolution on the negative electrode surface of zinc.In this paper,ZnSe interfacial layer was constructed on zinc negative electrode by electrodeposition method,and a full battery was assembled by Zn@ZnSe negative electrode material.The electrochemical performance of the battery was investigated.The results show that the zinc-ion battery with ZnSe interfacial layer still has good stability after 5000 charge and discharge cycles.
