Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(28)

Published: April 24, 2024

Abstract A major bottleneck limiting the commercialization of aqueous zinc ion batteries (AZIBs) is dendrite formation on (Zn) anode during plating/stripping process, which leads to rapid deterioration in performance and, consequently device failure. In this regard, researchers are trying design more stable anodes toward suppressing formation. One possible solution tackle problem and extend cycling life AZIBs modify surface by coating carbonaceous materials, enabling controlled charge flux uniform distribution. This work reports sustainable bio‐derived polylactic acid (PLA) as a layer anode. Carbonizing polymer under ambient conditions using high‐power nanosecond laser forms carbon‐coated foil, was directly utilized batteries. The fabricated laser‐processed PLA‐derived demonstrated an extended almost 1600 hours, significantly outperforming bare full battery assembled from as‐modified as‐prepared V 2 O 5 nanofibers cathode able deliver specific capacity 238 mAh g −1 at 1.0 with retention 70 % after 1000 cycles.

Construction of Selective Ion Transport Polymer at Anode–Electrolyte Interface for Stable Aqueous Zinc-Ion Batteries

ACS Nano, Journal Year: 2024, Volume and Issue: 18(11), P. 8452 - 8462

Published: March 1, 2024

Rampant dendrite formation and serious adverse parasitic reactions induced by migration of dissolved V/Mn cathode ions on Zn anode have hampered the high performance aqueous zinc-ion batteries (AZIBs). Inspired coordination chemistry between functional groups polymer electrolyte ions, a freestanding layer consisting dopamine-functionalized polypyrrole (DA-PPy) nanowires served as selective ion transport at anode–electrolyte interface to address these two issues, which could simultaneously avoid polarization caused introduction an additional interface. On one hand, DA-PPy displays excellent zinc charge transfer ability, well provides chemical homochanneling for interface, endow with properties guider physical barrier inhibition. other can trap excess transition metal fleeing from cathodes, thus serving barrier, preventing Vx+/Mnx+-passivation surface anode. Consequently, AZIBs based V2O5 MnO2 cathodes involving show great improvement in capacity retention.

The use of aqueous electrolytes and Zn metal anodes in Zn-based energy storage systems provides several benefits, including competitive density, excellent safety, low cost. However, dendrites growth slow ion transfer at the electrode/electrolyte interphase reduce cycle stability rate capability anode. Herein, V2O5-x interface layer was rationally controllably constructed on surface through situ spontaneous redox reaction between V2O5 layer, with an optimized thickness, plays a crucial role screening de-solvation, leading to uniform dispersion Zn2+ ions dendrite-free morphology. Moreover, as transports V element low-valence state allows oxygen anions bind more easily Zn2+. This interaction enables fast diffusion channel interfacial layer. Consequently, symmetric cells V@Zn achieve stable plating/stripping for than 1400 h 1 mA cm-2. In particular, full cell paired cathode exhibits capacity nearly 275.9 g-1 5 A after 2500 cycles without obvious deterioration, further highlighting potential practical applications.
