Intercalation Pseudocapacitive Zn2+ Storage with Hydrated Vanadium Dioxide toward Ultrahigh Rate Performance

“…As displayed in Figure S16 in the Supporting Information, the initial morphology of Zn foil showed a flat planar structure, and there was some array structure on the Zn anode surface after cycling, which was the Zn dendrites and zinc sulfate hydroxide as mentioned in previous papers. [42][43][44][45] In this study, crystal water molecules and defects are introduced into the VO 2 tunnel structure simultaneously. The lattice defects break the strong electrostatic interaction between ion and host structure, offering rapid ion diffusion pathway.…”

Dendrites issues and advances in Zn anode for aqueous rechargeable Zn‐based batteries

“…Advanced separators were designed to uniform Zn ion distribution, Liu et al proposed cross‐linked polyacrylonitrile (PAN)‐based cation exchange membrane (PAN‐S membrane) by employing Li 2 S 3 to react with PAN for high cation transport and homogeneous ionic flux distribution (Figure 7B) comparing to the nonwoven mat separator (Figure 7A). 79 Srinivasan et al reported a Nafion‐based separator with the interaction of Zn 2+ ‐SO 3 − achieving a dense and parallel surface texture 80 . The developing new separator system should consider the fabrication costs and mass production capability.…”

Recent progress on biomass‐derived ecomaterials toward advanced rechargeable lithium batteries

“…However, instable solid electrolyte interphase (SEI) as well as the resultant Li dendrite growth seriously cause safety concerns, once Li metal is implemented as an anode in a battery . In the view of being able to manipulate the mechanical properties by macromolecular chains as well as regulate Li ion flux and distribution by lithiophilic functional groups, biomass materials (eg, cellulose, starch, protein, lignin, chitin, polysaccharide) have been integrated into artificial SEI protective films for restraining Li plating and stripping to suppress the dendrite propagation . Recently, a natural agarose biopolymer film (AG) was reported as an enabling SEI protective layer.…”

[75][76][77][78][79] Recently, a natural agarose biopolymer film (AG) was reported as an enabling SEI protective layer. The assembled Li-Cu half cell with AG protective layer displayed higher Coulombic efficiency of 98% even after 100 cycles, much better than that with bare Cu foils (< 40% after 50 cycles), indicative of the excellent structure stability of bio-based AG films against Li metal anode.…”
