摘　　要：环境友好和低成本的锌离子混合超级电容器在大规模储能方面受到了相当大的关注。过渡金属硒化物因其具有高的可逆容量、优越的导电性和多功能结构而受到了人们的广泛关注。在本研究中,通过一个简单的液相反应合成了三维Cu_(2) Se/rGO水凝胶复合物。在以锌片和Cu_(2) Se/rGO分别为负、正极材料的锌离子混合电容器(ZHICs)中Cu_(2) Se/rGO电极在0.1 A·g^(-1)时电容为130 F·g^(-1),远远大于Cu_(2) Se颗粒的54.5 F·g^(-1)。这显示着水凝胶rGO的加入能够提高锌离子的存储容量。Environment-friendly and low-cost zinc-ion hybrid capacitors have received considerable attention for large-scale energy storage.Transition metal selenides have attracted considerable attention because of their high reversible capacity,superior electrical conductivity and versatile structures.Cu_(2) Se/rGO hydrogel were synthesized via a simple liquid-phase reaction.In zinc-ion hybrid capacitors with the Cu_(2) Se/rGO and Zn as the negative and positive materials,Cu_(2) Se/rGO anodes exhibited a high reversible capacity of 130 F·g^(-1) at 0.1 A·g^(-1),which were much greater than those of Cu_(2) Se nanoparticles(54.5 F·g^(-1)).It was demonstrating that the hydrogel rGO can enhance the binding of Cu_(2) Se,which will greatly improve the Zn storage capacity.
