Alternately electrodeposited mesoporous NiCoSe₂@MnO₂ nanocomposite-anchored Ni–Co layered double hydroxide nanoneedles for hybrid supercapacitors

Abstract

A rational strategy for preparing effective electrode materials is crucial for high-performance electrochemical energy storage devices. Herein, a facile route is developed to construct hierarchical composite electrodes (NiCoLDH@NiCoSe2@MnO2) consisting of...
