“…In this strategy, core-shell structures, applying template substances as the core and LDH as the shell, are normally constructed. The LDH-based core−shell architectures have been widely proven to be conducive to achieving improved energy storage performance [31][32][33]. Firstly, the anchoring effect decreases the stacking probability of LDH nanosheets with free movement, thus increasing the exposed active sites and improving stability.…”

The application of transition metal hydroxides has long been plagued by its poor conductivity and stability as well as severe aggregation tendency. In this paper, a novel hierarchical core–shell architecture, using an F-doped Co(OH)2 nanorod array (Co(OH)F) as the core and Mn/Ni co-doped Co(OH)2 nanosheets (NiCoMn-LDH) as the shell, was constructed via an MOF-mediated in situ generation method. The obtained Co(OH)F@ NiCoMn-LDH composites exhibited excellent supercapacitive performance with large specific capacitance as well as improved rate capability and long-term stability. The effect of the Ni/Mn ratio on the supercapacitive performance and energy storage kinetics was systematically investigated and the related mechanism was revealed.
