Suppressing dendrite growth with a poly(1-aminoanthraquinone) coating in a VS4 nanoflowers@carbon nanotubes composite based long lasting zinc-ion battery

Recent advance and design strategies of chalcogenides for high-performance aqueous zinc-ion batteries

“…However, the practical application of VS 4 for Zn 2+ storage is limited by substantial volume changes and the dissolution of produced polysulfide during cycling. To address these issues, carbon-based materials such as graphene oxide (GO), rGO, N-doped graphene aerogel (NGA), and CNTs are used to alleviate pulverization and structural collapse of VS 4 [100][101][102][103]. Specifically, Chen et al prepared a VS 4 @rGO composite with optimized morphology, exhibiting an ultrahigh specific capacity of 450 mA h g −1 at 0.5 A g −1 and an outstanding rate capability of 313.8 mA h g −1 at 10 A g −1 , with a high capacity retention of 82% over 3500 cycles (figure 9(g)) [101].…”

“…Accordingly, efficient reliable routes including construction of a micro/nano-structure and introduction of carbonaceous materials with excellent mechanical and conductive properties have been taken to deal with the aforementioned drawbacks. 8,19,20 At present, several carbonaceous materials have been used to compound with VC micro/nano materials to meliorate their energy storage performance. 16,20,21 Among them, graphene has drawn considerable concerns thanks to its distinct physicochemical properties.…”

“…The low electrical conduction, sluggish ion diffusion dynamics, morphology agglomeration, structural collapse, and solubility in aqueous electrolytes during repeated charge and discharge procedures lead to an unsatisfactory electrochemical real performance of VCs, which greatly impedes its further application in AZIBs. Accordingly, efficient reliable routes including construction of a micro/nano-structure and introduction of carbonaceous materials with excellent mechanical and conductive properties have been taken to deal with the aforementioned drawbacks. ,, At present, several carbonaceous materials have been used to compound with VC micro/nano materials to meliorate their energy storage performance. ,, Among them, graphene has drawn considerable concerns thanks to its distinct physicochemical properties. Nevertheless, in view of the existence of π–π interactions and strong van der Waals working force in the graphene nanolayers, their aggregation and restack occurred frequently, resulting in the inheritance of a graphite nature. , This is unfavorable for the utilization of graphene on high-performance energy storage systems.…”
