Templated synthesis of spinel cobaltite MCo2O4 (M=Ni, Co and Mn) hierarchical nanofibers for high performance supercapacitors

CuCo2O4/NiCo-Metal–Organic Framework Nanoflake Arrays for High-Performance Supercapacitors

“…In addition, the GCD curves of CuCo 2 O 4 /NiCo-MOF at various current densities (2–30 mA/cm 2 ) were tested and are depicted in Figure d. The obvious charge–discharge plateau proves that it is an energy storage material dominated by diffusion control. − For comparison, the CV curves at different scan rates and GCD curves at different current densities of CuCo 2 O 4 and NiCo-MOF are shown in Figures S5 and S6. On the basis of these GCD curves, the capacities of CuCo 2 O 4 , NiCo-MOF, and CuCo 2 O 4 /NiCo-MOF are calculated and are summarized in Figure e.…”

Advances in pseudocapacitive and battery-like electrode materials for high performance supercapacitors

“…In the last few years another spinel cobaltite, CuCo 2 O 4 , has been considered as a potential SC electrode due to its improved electrical conductivity and better electrochemical activity. 349–353 Inspired by these characteristics, several morphologies of CuCo 2 O 4 have been synthesized on different substrates. In particular, flower-like CuCo 2 O 4 , 354 macroporous CuCo 2 O 4 nanograsses, 313 CuCo 2 O 4 nanocubes, 355 CuCo 2 O 4 nanosheets, 356 CuCo 2 O 4 nanobelts 357 and CuCo 2 O 4 nanowires 358 have been investigated as promising SC electrodes.…”

Activity engineering of cobalt-based oxide materials for high performance supercapacitors: from morphology regulation to structural optimization

“…Therefore, spinel-structured materials with more complex morphologies were prepared via a template method, and they were expected to show greatly improved performance. Yin et al 51 prepared a spinel cobaltate–MCo 2 O 4 (H–MCo 2 O 4 NFS, M = Ni, Co, Mn) via a template method. Many ultra-small nanosheets were rooted on the surface of the nanofibers, which not only provided more active sites for electrochemical reactions, but also shortened the diffusion paths of ions and electrons.…”
