A Functional Intermediate Layer for Inhibiting Zinc Dendrite Growth to Improve the Performance of Aqueous Zinc Ion Batteries

Опубликована: Янв. 1, 2025

Aqueous zinc-ion batteries (AZIBs) are extensively investigated as lithium battery alternatives because of their high energy density, low redox potential, and enhanced safety. However, zinc dendrite formation severe side reactions impede practical application. A polymer-functionalized interlayer (PVDF-CTFE/MCA-HOFs) prepared from melamine cyanurate hydrogen-bonded organic framework particles (MCA-HOFs) poly(vinylidene fluoride)-trichloroethylene (PVDF-CTFE is presented. Not only do they play a role in enhancing the desolation effect battery, but uniformly dispersed also form uniform electric field on surface to guide transport ions. The results demonstrate that PVDF-CTFE/MCA-HOFs has ionic conductivity (1.90 S m-1), nucleation overpotential (69.45 mV), elevated mobility (0.65), achieving stable cycling for 950 h at 2.5 mA cm-2. Compared with single GF separator, it reduces overpotential, accelerates kinetics, effectively inhibits growth dendrites. Furthermore, full incorporating exhibit peak specific capacity 274.9 mAh g-1 3 g-1, retaining 120.0 after 4000 cycles, contrasting rapid decline below 70.0 3000 cycles alone. This innovation significantly enhances charge/discharge longevity.

Abstract Aqueous zinc metal batteries (AZMBs) have attracted increasing attention due to their low cost and high energy density. However, practical applications are constrained by Zn dendritic growth, self‐corrosion, poor low‐temperature adaptability. Herein, a multi‐component hydrogel electrolyte is proposed address these challenges. Specifically, dimethyl sulfoxide added substitute H 2 O in the 2+ solvation sheath disrupt intrinsic H─bond network, suppressing interfacial parasitic reactions induced active water achieving ultra‐low freezing point (−60 °C); while acylamino groups on polyacrylamide chains utilized coordinate with SO 4 2− , leading homogeneous flux reduced by‐products accumulation. Benefitting from synergistic effects, stable plating/stripping average Coulombic efficiency of 99.5% for 1200 h at 0.5 mA cm −2 achieved. To manifest superiority electrolyte, free‐standing α‐MnO /single‐walled carbon nanotube film designed as cathode. The resulting AZMB exhibits large specific capacity, prominent rate capability (157.5 mAh g −1 10 C), cyclic stability, good performance (68.8% capacity retention −20 °C), which also demonstrates excellent safety under extreme conditions hammering, cutting, burning, punching, soaking. This work provides an inspired strategy build robust, multi‐functional, inexpensive aqueous batteries.

Abstract The industrial development of Zn‐ion batteries requires high performance even with lean‐electrolyte. Nevertheless, lean‐electrolyte can exacerbate concentration polarization at the interface electrode/electrolyte, leading to significant Zn corrosion and battery failure. Here, a stable ion‐rich protective layer (TMAO‐Zn) is constructed by unique zwitterion structure trimethylamine N‐oxide (TMAO). TMAO characterized direct connection between positive negative charges (N + ‐O − ) minimal dipole moment, which renders weak interactions form TMAO‐Zn 2+ , thereby reducing promoting rapid uniform deposition . Furthermore, O exhibits higher electrophilic index, indicating stronger propensity for hydrogen bond active free water in inner Helmholtz (IHL), mitigating under extreme conditions low electrolyte‐to‐capacity ratio (E/C ratio). Consequently, symmetrical enables cycling over 250 h 15 µL mA −1 Additionally, Zn/I₂ pouch E/C 21.2 provides ultra‐high specific capacity 96 cycles (capacity retention rate 98.3%).
