超级电容器由于其重要的应用而在过去几十年中引起了人们的广泛兴趣，但其中大多数都集中在单独或简单的金属氧化物上。在这里，通过一种简便且经济有效的方法报道了一种由多组分MnCo2O4@Ni(OH)(2)带基核壳纳米花组成的新型超级电容器电极。这种混合电极表现出显着增强的比电容。基于这种独特的混合纳米花作为阳极和活性炭膜作为阴极的不对称超级电容器表现出高能量密度、高功率密度和长循环寿命。
Supercapacitors have attracted much interest in the past decades owing to their important applications, but most of them are focused on solitary or simple metal oxides. Here, a novel supercapacitor electrode composed of multicomponent MnCo2O4@Ni(OH)(2) belt-based core-shell nanoflowers is reported by a facile and cost-effective method. This hybrid electrode exhibits a significantly enhanced specific capacitance. An asymmetric supercapacitor based on this unique hybrid nanoflowers as anode and an activated carbon film as cathode demonstrates high energy density, high power density, and long cycling lifespan.
