A MnCo2O4@NiMoO4 Core‐Shell Composite Supported on Nickel Foam as a Supercapacitor Electrode for Energy Storage

“…Liu et al. reported MnCo 2 O 4 nanosheets@MnMoO 4 nanosheets core‐shell nanoarrays on Ni foam as a binder‐free electrode for supercapacitors, and MnCo 2 O 4 @MnMoO 4 electrode demonstrates significantly enhanced electrochemical performances compared with the single MnCo 2 O 4 or MnMoO 4 electrodes . Our recent work shows that homogeneous core‐shell NiCo 2 S 4 nanostructure has better electrochemical performances than that of the NiCo 2 S 4 nanotubes …”

“…[22][23][24] For instance, Wang et al reported hierarchical core/shell structured MnCo 2 O 4 @CoS arrays which exhibit enhanced electrochemical performances than the two components. [25] [26] Our recent work shows that homogeneous coreshell NiCo 2 S 4 nanostructure has better electrochemical performances than that of the NiCo 2 S 4 nanotubes. [27] Based on the above consideration, herein, a core-shell structured MnCo 2 O 4 @NiMoO 4 composite has been synthesized on Ni foam by a two-step process.…”

Hierarchical MnCo2O4/NiMn Layered Double Hydroxide Composite Nanosheet Arrays on Nickel Foam for Enhanced Electrochemical Storage in Supercapacitors

“…These values were higher than that of the MnCo 2 O 4 electrode (55.0 % capacitance retention). In addition, the specific capacitance and rate capability of the MnCo 2 O 4 /Ni 3 Mn LDH composite electrode were also superior to those reported MnCo 2 O 4 ‐based composite electrodes (Table ) ,. The significantly improved electrochemical performance of the MnCo 2 O 4 /NiMn LDH composite electrodes probably originated from the good synergistic effects of the composite compositions containing layer‐by‐layer microstructures, which fully engaged the electrochemical performance of the MnCo 2 O 4 and NiMn LDH.…”

“…The specific capacitance at 20 A g −1 was found to be 702 F g −1 . Our group also reported the synthesis of MnCo 2 O 4 @MnMoO 4 core‐shell NAs with a specific capacity that was four times greater than the single MnCo 2 O 4 NAs (885 C g −1 at 3 A g −1 ) . In addition, 71 % of its original capacitance was obtained at 30 A g −1 .…”

“…By fully integrating the advantages of each component, nanocomposites electrodes can achieve significantly improved electrochemical performance compared to the individual components. Using this technical approach, considerable endeavors have been devoted to the design and preparation of MnCo 2 O 4 ‐based nanocomposites employing different components and hierarchical microstructures . For example, Yang et al.…”
