Herein, we bridge interfacial electrochemistry with industrial-scale catalyst manufacturing via evaporation-condensation, producing monodisperse Ni nanospheres (200–1,000 nm) at >2 tons per batch. Systematic investigations reveal a volcano-type size-activity relationship: ∼600 nm nanospheres (Ni600) exhibit optimal EGOR performance. In situ spectroscopies, finite-element analysis, and density functional theory calculations demonstrate that increasing particle size weakens the local electric field intensity, enhancing K+ accumulation and tuning the adsorption energetics of reactants, intermediates, and products.

This perspective showcases recent experimental outcomes, mechanistic insights, and structural dependencies to outline a roadmap for exploiting liquid-phase piezo-electrics. Highlighting the role of pressure-induced liquid-to-crystalline transitions, ion pair organization, and compositional tuning, we propose design strategies that could unlock applications ranging from flexible sensors to piezo-pneumatic devices. Unlike traditional liquids, where the application of pressure transfers mechanical load with no chemical or physical change, in these systems, the applied stress triggers a physical or chemical transformation, such as a phase transition, crystallization, or a change in molecular ordering. Such transformations are particularly important because they can generate non-centrosymmetric crystalline domains, which are essential for the emergence of piezoelectric behavior. This phenomenon is especially relevant in solid polymer electrolytes, where stress-induced crystallization can impart piezoelectric functionality.
