Sophisticated Structural Tuning of NiMoO(4)@MnCo(2)O(4) Nanomaterials for High Performance Hybrid Capacitors

NiMoO(4) is an excellent candidate for supercapacitor electrodes, but poor cycle life, low electrical conductivity, and small practical capacitance limit its further development. Therefore, in this paper, we fabricate NiMoO(4)@MnCo(2)O(4) composites based on a two-step hydrothermal method. As a supe...

description NiMoO(4) is an excellent candidate for supercapacitor electrodes, but poor cycle life, low electrical conductivity, and small practical capacitance limit its further development. Therefore, in this paper, we fabricate NiMoO(4)@MnCo(2)O(4) composites based on a two-step hydrothermal method. As a supercapacitor electrode, the sample can reach 3000 mF/cm(2) at 1 mA/cm(2). The asymmetric supercapacitor (ASC), NiMoO(4)@MnCo(2)O(4)//AC, can be constructed with activated carbon (AC) as the negative electrode, the device can reach a maximum energy density of 90.89 mWh/cm(3) at a power density of 3726.7 mW/cm(3) and the capacitance retention can achieve 78.4% after 10,000 cycles.
