In this work, a ternary nickel‑cobalt‑iron LDH (NiCoFe-LDH) is synthesized via metal ion etching, leveraging synergistic intermetallic electronic interactions to enhance electrocatalytic performance. The as-prepared NiCoFe-LDH exhibits outstanding electrocatalytic performance under alkaline conditions, achieving low overpotentials of 79.60 ± 0.50 mV for the hydrogen evolution reaction (HER) and 373.40 ± 0.50 mV for the oxygen evolution reaction (OER) at 10 mA cm^-2, along with Tafel slopes of 149.61 ± 0.50 and 77.84 ± 0.50 mV dec^-1, respectively.

Herein, a unique interlayer-structured MnS@MXene cathode is designed and synthesized through an electrostatic anchoring combined with confined sulfidation approach, which enables in situ growth of MnS in MXene matrices, overcoming the challenges of weak interfacial bonding and uneven particle distribution encountered in traditional composite fabrication methods. The periodic stacking of MnS nanoparticles and MXene lamellae forms a large number of heterogeneous interfaces, which construct a good conductive network while offering an increased number of active sites for electrochemical reactions. When employed as a cathode material for AZIBs, the electrochemical activity of MnS is unlocked by the initial charging process, and it exhibits considerable capacity of 325 mAh g^-1 at a current density of 0.2 A g^-1 and superior cycling performance with a specific discharge capacity of 274 mAh g^-1 even after 400 cycles at a current density of 0.5 A g^-1. Even at a high current density of 2 A g^-1, a reversible specific capacity of 105 mA g^-1 is still achieved after 2500 cycles.

A key challenge lies in the rational design of ligands to eliminate concentration polarization caused by mismatched diffusion and interfacial reaction rates, thereby inducing and regulating uniform zinc deposition. In this study, we propose a thermodynamic descriptor-guided ligand screening strategy, using the metal-ligand stability constant (log K) as a quantitative criterion to simultaneously optimize deposition morphology and interfacial ion kinetics. Guided by this principle, nitrilotriacetic acid (NTA, log K = 11.98) is identified as a robust chelating agent under strongly alkaline conditions (pH > 14). Its moderate coordination strength enables the disruption of the native Zn²⁺-H₂O network, effectively suppressing hydrogen evolution while maintaining near-theoretical Zn²⁺ desolvation kinetics. In situ microscopy and electrochemical analyses reveal that NTA directs preferential Zn(002) growth, yielding dendrite-free deposition at ultrahigh current densities (80 mA cm^-2) and high areal capacities (40 mAh cm^-2). Furthermore, NTA facilitates efficient Zn²⁺ diffusion (5.77 × 10^-7 cm²/s), outperforming strong chelators such as ethylenediaminetetraacetic acid. As a result, Zn//Zn symmetric cells exhibit stable cycling over 400 h, while NTA-enabled ZnFe flow batteries achieve 700 cycles with 99 % coulombic efficiency and minimal capacity decay.
