In order to address these challenges, optimization of the electrolyte composition is a practical and straightforward way to improve the Coulombic efficiency of ZIBs and the reversibility of zinc plating/stripping. Here, 2-piperazinone (2-PZ) stands out for its planar structure, abundant polar groups, and cost-effectiveness and demonstrates a hybrid electrolyte consisting of 0.2 g L^–1 2-PZ and 1 mol L^–1 ZnSO₄ that significantly improves the reversibility of zinc compared to a pure ZnSO₄ electrolyte. Spectral analysis and computations based on density functional theory revealed the ability of 2-PZ to replace free molecules of water to rebuild the solvation structure of Zn²⁺. In situ characterization further confirmed that dendrite growth on zinc metal anodes was effectively inhibited.

The alloy was developed based on four specific design criteria: (1) valence electron concentration (VEC) between 6.2 and 6.5, (2) atomic size mismatch (δ) of at least 9.7%, (3) an atomic radius ratio of hydride-forming to non-hydride-forming elements (<i>r</i>_A/<i>r</i>_B) ranging from 1.149 to 1.219, and (4) stability of the C14 Laves phase as the primary phase, as confirmed by CALPHAD. The resulting alloy crystallized predominantly in the C14 Laves phase (92.8 wt %), with a minor body-centered cubic (BCC) phase. Transmission electron microscopy (TEM) results revealed coherent nanograin boundaries, particularly at the C14/BCC interphase, facilitating rapid hydrogenation kinetics. After a one-step simple thermal activation, the alloy reversibly absorbed 1.4 wt % of hydrogen with relatively low hysteresis and fast kinetics, attributed to a preferential hydride nucleation at grain boundaries. In terms of thermodynamic properties, the chemical composition, designed according to the aforementioned criteria, should be considered, with the high iron content (41%) playing a critical role. The high atomic percentage of iron, a non-hydride-forming element, stabilizes the C14 phase due to the significant negative contribution of the interaction parameter (Ω_ij) of the Fe–Zr pair (Ω_ij = −118.4 kJ/mol), which results in a negative enthalpy of mixing in the C14 structure.
