Sacrificial template synthesis of hollow-structured NiCoP microcubes as novel electrode materials for asymmetric supercapacitors

Abstract

Transition bimetallic phosphides with optimal composition and morphology are efficient electrocapacitive materials for asymmetric supercapacitor (ASC). Herein, unique bimetallic phosphide of NiCoP with hollow microcubes structure was synthesized by a...

Recent advances in Ni-materials/carbon nanocomposites for supercapacitor electrodes

“…The various supercapacitors based on the Ni materials//active carbon electrodes have been employed in electrochemical applications, and the novel results of the reported papers are tabulated in Table 4. 182–219 The utilization of active carbon in supercapacitors highlights its valuable role in improving energy storage capabilities and supporting advancements in various fields where efficient power delivery and rapid energy transfer are essential. Ni(OH) 2 /ZIF-67-derived CoS core/carbon cloth (Ni(OH) 2 /CoS/CC) was used in the supercapacitor of Ni(OH) 2 /CoS/CC (cathode)//AC (anode) that revealed a remarkable energy density as well as its excellent electro-catalytic activity towards methanol oxidation.…”

“…Furthermore, an asymmetry supercapacitor was fabricated by using the NiCoP-HMCs of the (+) electrode and AC as the negative electrode with a high specific energy of 78.2 W h kg À1 . 211 Stable a-phase NiCoAl hydroxides were used in a NiCoAl-10 supercapacitor electrode with excellent specific capacitances of 19.27 F cm À2 . A supercapacitor of NiCoAl-10// AC also exhibited a remarkable energy density and capacity retention.…”
