Heterostructure of MnSe2@NiCo2Se4 as novel electrode material for high-performance asymmetric supercapacitors

Hydrothermal Self-Assembly of α-MnSe-Loaded Honeycomb-Like Biomimetic Ti3C2Tx/Graphene Aerogel Microstructure (α-MnSe/Ti3C2Tx/rGO) as Efficient Electrode Material for Energy Storage Application

“…Further, it is noteworthy that the specific capacity and capacity retention of MnSe/TCGA are significant as compared to previously reported similar electrode materials such as α-MnSe nanosheets, porous nanocellular MnSe, honeycomb-like-NMS, MnSe 2 @NiCo 2 Se 4 -2, MNS@NF, Ti 3 C 2 -Mn 3 O 4 , MnS/N-doped RGO, and MnS/RGO@Ni foam (see Table ).…”

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

“…The smaller the slope (k) of this fitted straight line, the lower the total series resistance in the electrode/electrolyte system. 32 The k value for NiCoLDH@-NiCoSe 2 @MnO 2 -3 is really larger than that of the NiCoLDH@-NiCoSe 2 electrode (Fig. 7a), revealing the increased resistance of electrodes and thus the decreased electrochemical performance due to the large loading of MnO 2 .…”

“…The Ni 2p and Co 2p deconvoluted core level spectra (Fig. 5b and c) contain two groups of peaks for spin–orbit splitting (2p 3/2 and 2p 1/2 ) relating to Ni 2+ at 853.7 eV, Co 2+ at 781.9 eV and 798.0 eV, Ni 3+ at 856.7 eV and 874.5 eV, and Co 3+ at 778.8 eV and 793.7 eV, 32 respectively. As shown in Fig.…”

Microwave-Assisted Synthesis of Few-Layer Ti3C2Tx Loaded with Ni0.5Co0.5Se2 Nanospheres for High-Performance Supercapacitors

“…In Figure 4c, the Ni 2p spectrum reveals two sets of peaks, corresponding to Ni 3+ (873 eV and 855.1 eV) and Ni 2+ (869.8 eV and 852.3 eV), along with satellite peaks (labeled as Sat.) at 878 eV and 860.4 eV [25][26][27]. The Co 2p spectrum (Figure 4c) exhibits peaks related to Co 2+ (780.7 eV and 796.5 eV) and Co 3+ (791.7 eV and 777.4 eV) [28].…”
