Metal–organic framework-derived nitrogen-doped carbon-confined CoSe₂ anchored on multiwalled carbon nanotube networks as an anode for high-rate sodium-ion batteries

Abstract

Metal selenides as potential alternative candidates for sodium storage have remarkable hopeful applicability due to the high theoretical specific capacity. However, the huge volume change and sluggish electrode kinetics during...

Low-content SnO2 nanodots on N-doped graphene: lattice-confinement preparation and high-performance lithium/sodium storage

“…2 In examining what may lie beyond LIBs, [3][4][5] the sodium-ion battery (SIB) appears to be a promising supplement or even a potential alternative to LIBs in large-scale energy storage systems, due to the abundant sodium resources and low cost, as well as, in particular, working principles that are similar to those of LIBs. [6][7][8][9][10][11][12] The large ionic radius of Na + (1.02 Å), however, results in sluggish transfer kinetics, and poor energy density and cycling performance of SIBs. Therefore, it is of great sig-nificance to develop high-performance anode nanomaterials for LIBs and SIBs.…”

Self-assembled nanoflower-like FeSe2/MoSe2 heterojunction anode with enhanced kinetics for superior-performance Na-ion half/full batteries

“…3f ), the rate performance of the FMSe electrode is outstanding. [38][39][40][41][42][43][44][45][46][47] Furthermore, the long-term cycling performance of the FMSe electrode is shown in Fig. 3g, the long-term cycling stability of FMSe is further evaluated at a high current density of 5.0 A g −1 , and the capacity is maintained at 352.2 mA h g −1 even after 4200 loops.…”

Synergistic γ‐In2Se3@rGO Nanocomposites with Beneficial Crystal Transformation Behavior for High‐Performance Sodium‐Ion Batteries

“…The rate performance of the γ‐In 2 Se 3 @rGO‐0.06 electrode was also compared with the typical MS electrodes in SIBs reported recently (Figure 6e ; Table S3 , Supporting Information). [ 37 , 61 , 62 , 63 , 64 , 65 , 66 ] The distinct advantage in rate capacity retention especially at high current densities signifies the great application potential of β‐In 2 Se 3 based electrode materials for high‐power SIBs.…”
