Aqueous zinc-metal batteries have attracted extensive attention due to their outstanding merits of high safety and low cost. However, the intrinsic thermodynamic instability zinc in aqueous electrolyte inevitably results hydrogen evolution, consequent generation OH- at interface will dramatically exacerbate formation dead dendrites. Herein, a dynamically interfacial pH-buffering strategy implemented by N-methylimidazole (NMI) additive is proposed remove detrimental zinc/electrolyte real-time, thus eliminating accumulation by-products fundamentally. Electrochemical quartz crystal microbalance molecular dynamics simulation reveal existence an absorption layer assembled NMI protonated (NMIH+ ), which acts as ion pump for replenishing with protons constantly. Moreover, situ pH detection method micro-sized spatial resolution based on ultra-microelectrode technology developed probe evolution diffusion layer, confirming stabilized chemical environment NMI-containing electrolyte. Accordingly, NMI, excellent cumulative plating capacity 4.2 Ah cm-2 ultrahigh Coulombic efficiency 99.74% are realized electrodes. Meanwhile, NMI/NMIH+ buffer can accelerate dissolution/deposition process MnO2 /Mn2+ cathode, leading enhanced cycling capacity.

3D porous Zn-metal anodes have aroused widespread interest for Zn-ion batteries (ZIBs). Nevertheless, the notorious "top-growth" dendrites caused by intrinsic top-concentrated ions and randomly distributed electrons may ultimately trigger a cell failure. Herein, an electron/ion-flux dual-gradient Zn anode is reported dendrite-free ZIBs adopting printing technology. The 3D-printed with layer-by-layer bottom-up attenuating Ag nanoparticles (3DP-BU@Zn) establishes electron/ion fluxes, i.e., internal gradient electron flux created bottom-rich conductive nanoparticles, ion resulting from zincophilic which pump toward bottom. Meanwhile, 3D-printing-enabled hierarchical structure continuously conducting network endow unimpeded transfer diffusion among electrode, dominating bottom-preferential deposition behavior. As result, 3DP-BU@Zn symmetrical affords highly reversible plating/stripping extremely small voltage hysteresis of 17.7 mV superior lifespan over 630 h at 1 mA cm-2 mAh . 3DP-BU@Zn//VO2 full exhibits remarkable cyclic stability 500 cycles. This unique strategy sheds light on roadmap next-generation safe durable batteries.

Abstract Low-cost, high-safety, and broad-prospect aqueous zinc−manganese batteries (ZMBs) are limited by complex interfacial reactions. The solid−liquid state of the cathode dominates Mn dissolution/deposition process ZMBs, especially important influence on mass charge transfer behavior Zn2+ Mn2+. We proposed a quasi-eutectic electrolyte (QEE) that would stabilize reversible deposition favorable reaction kinetic manganese-based cathodes in long cycle optimizing transfer. emphasize initial energy barrier is not main factor affecting cycling performance, good kinetics induced during more conducive to stable battery, which has been confirmed theoretical analysis, quartz crystal microbalance with dissipation monitoring, depth etching X-ray photon-electron spectroscopy, etc. As result, QEE maintained specific capacity 250 mAh g−1 at 0.5 A after 350 cycles batteries. density retention rate ZMB increased 174% compared conventional electrolyte. Furthermore, multi-stacked soft-pack battery cathodic load 54.4 mg 200 for 100 cycles, demonstrating its commercial potential. This work proves feasibility adapting lean-water ZMBs.

Rechargeable Zn batteries hold great practicability for cost-effective sustainable energy storage but suffer from irreversibility of the anode in aqueous electrolytes due to parasitic H2 evolution, corrosion, and dendrite growth. Herein, we report a non-flammable, dilute, hydrous organic electrolyte by dissolving low-cost hydrated Zn(ClO4)2·6H2O trimethyl phosphate (TMP), which homogenizes plating/stripping enables situ formation Zn3(PO4)2-ZnCl2-rich interphase stabilize anode. A dilute 0.5 m Zn(ClO4)2·6H2O/TMP featuring H2O-poor Zn2+-solvation sheath low water activity significantly enhanced reversibility wider electrochemical window than concentrated counterpart. In this formulated electrolyte, exhibits high efficiency 99.5% over 500 cycles, long-term cycling 1200 h (5 mA cm-2 at 5 cm-2) stable operation 50 °C. The results would guide design practical rechargeable employing metallic electrode materials.
