The reversibility and stability of aqueous zinc-ion batteries (AZIBs) are largely limited by water-induced interfacial parasitic reactions. Here, dimethyl(3,3-difluoro-2-oxoheptyl)phosphonate (DP) is introduced to tailor primary solvation sheath inner-Helmholtz configurations for robust zinc anode. Informed theoretical guidance on process, DP with high permanent dipole moments can effectively substitute the coordination H

Research on the reversibility and long-term cycling stability of zinc-ion batteries (ZIBs) over a wide temperature range remains limited. One major challenge with gel electrolytes is ensuring interface Zn metal anodes under varying conditions. In this study, we introduce multicomponent electrolyte that effectively addresses challenges associated high current densities ranges. This advanced synthesized via polymerization poly(VDF-TrFE-CTFE) within polyimide fiber network, which enables hydrogen-free dendrite-free deposition/stripping 4350 h at 1 mA cm-2, even 1500 from -60 to 60 °C, sustaining 20 cm-2 operation. Fluorine-rich components promote self-adaptive bilayer solid interphase (SEI) comprising an ultrathin amorphous outer layer inorganic/organic inner (ZnF2-ZnS-ZnO-ZnCO3), synergistically suppressing side reactions guiding uniform deposition piezoelectric effects. Consequently, all-solid-state ZIBs paired iodine cathode achieve stability: 36,500 cycles 5 A g-1 (30 °C) -30 setting benchmarks for extreme-condition performance. work advances interfacial engineering high-rate, wide-temperature through rational design SEI modulation.

Abstract The main challenges in aqueous Zn metal batteries (AZMBs) are enhancing energy density and cycling life, which require low deposition/stripping overpotential a stable anode/electrolyte interface. Herein, hollow mesoporous Na 3 V 2 (PO 4 ) coated with carbon (HMNVP/C) is designed as the anode protective layer (HMNVP/C@Zn). zincophilic numerous ion channels accelerates 2+ desolvation, while structure promotes rapid migration through artificial solid electrolyte interface (ASEI). Diffusion rate differences between external wall core lead to enrichment flux homogenization at Consequently, HMNVP/C@Zn symmetric cell achieves an ultralow of 13.0 mV 1 mA cm −2 , for over 1200 h 0.2 mAh without dendrite growth. Additionally, first time, electrochemical process zinc decomposed into seven steps, determine relaxation time range ASEI by situ impedance spectroscopy (EIS) distribution times (DRT) analysis. It noted that within HMNVP/C significantly reduces subsequent crystal This novel design characterization technique offer valuable insights preparing advanced AZMBs.
