Hierarchical NiCo-LDH/NiCoP@NiMn-LDH Hybrid Electrodes on Carbon Cloth for Excellent Supercapacitors

Abstract

To realize high-performance and long life span of supercapacitors, highly electrochemical active materials and rational design of structure are highly desirable. Herein, the hierarchical NiCo-LDH/NiCoP@NiMn-LDH hybrid electrode (NCLP@NiMn-LDH) was synthesized on carbon cloth via hydrothermal reaction and phosphorization treatment. Owing to the import of NiCoP and design of core-shell structure, the hybrid electrode showed significantly improved electrochemical performance. The as-fabricated hybrid electrode exhibited a high specific capacitance of 2318 F g-1 at 1A g-1, with a superior cyclic stability. Additionally, an asymmetric supercapacitor (NCLP@NiMn-LDH//AC) was assembled with a voltage window of 1.5 V. The ASC device delivered a maximum energy density of 42.2 Wh kg-1 at a power density of 750 W kg-1.
