Preparation of a Cu-Doped Graphene Oxide–Glutamine Nanocomposite for Supercapacitor Electrode Applications: An Experimental and Theoretical Study

“…In fact, the synthesized Cu/G-GO nanocomposite can be considered as a hybrid material composed of two different capacitive materials, i.e., pseudocapacitive (copper) and EDLC (G-GO). Therefore, both non-Faradic and Faradaic reactions are involved in the collection of charges. , …”

Binder-free MoSe/MMSe composite and onion-derived activated carbon electrode materials for high-performance hybrid supercapacitors

“…16 Nagaraju et al synthesized a Cu 6.0 Se 5.22 /Ni 2.0 V 4.0 Se 8.0 electrode, exhibiting a high specic capacity of 94.4 mA h g −1 with good cycling retention of 103.8% aer 8000 GCD cycles. 17 The FeCoSe 2 @-NiCo electrode prepared by L. Wan et al revealed a high specic capacity of 220.9 mA h g −1 with 83.5% capacity retention aer 5000 GCD cycles. 18 Muralee Gopi et al reported that a CoFe 2 -Se 4 @CoNiSe 2 electrode showed a high specic capacity of 183.4 mA h g −1 with a good cycling retention of 99.2% aer 3000 GCD cycles.…”

Fabrication of amorphous Co/Mo–MnSex electrode materials for high-performance hybrid supercapacitors

“…28 Previous reports related to MOF derivatives confirmed that the increased addition of metal elements to metal selenides resulted in the generation of additional redox-centered metal selenides, increasing the strain to improve the cycle life of electrodes. [29][30][31] Meanwhile, the different skeleton structures formed by selenides increased the porosity and reduced the energy barrier for ion diffusion, resulting in an enhancement in electrochemical performance. 32 However, to the best of our knowledge, publications on the application of trimetallic selenides, especially MOF-derived trimetallic selenides, in energy storage are scarce.…”
