However, the ambiguous role of closed-pore size, volume, and particularly the less-reported closed-pore concentration in governing plateau capacity hinders the rational design of closed-pore structures. Herein, we develop a hydrothermal zinc oxide template approach that precisely regulates closed-pore size, volume, and concentration through precursor zinc content modulation, thereby investigating the critical determinants of plateau capacity. Electrochemical analysis reveals a lack of positive correlation between individual closed-pore size/volume metrics and plateau capacity. We establish a quantitative formula for calculating closed-pore concentration, confirming this parameter delivers a significant linear correlation with plateau capacity.

Unfortunately, the high charge density and strong Coulomb interaction of Al³⁺ limit this application. To address the challenge, this work innovatively used aluminum salt as an electrolyte additive and achieved efficient operation of zinc and nickel metal batteries at ultra-low temperatures by synergistically utilizing the advantages of anions and cations. XPS and <em>in-situ</em> Raman spectroscopy reveal that anions (Cl⁻ and ClO₄⁻) can achieve effective insertion/extraction in the cathode, significantly improving the redox kinetics of the metal battery. Meanwhile, Al³⁺, which offers a low binding energy of -9.12 eV with water molecules, achieves excellent deposition/stripping reversibility on the metallic Zn and Ni surface. This synergistic effect of anions and cations not only improves the open circuit voltage of the battery, but also significantly reduces the ion diffusion resistance at low temperatures. Consequently, Zn//Zn and Ni//Ni symmetric cells can operate for more than 400 h at -30°C, and the polarization voltage remains highly stable. Impressively, zinc and nickel metal batteries with 2 m AlCl₃ as the electrolyte additive are able to maintain voltages of 1.28 V and 0.55 V, respectively, after 550 h of standing at -30°C. The zinc metal battery still has a discharge specific capacity of 118.5 mAh g⁻¹ and a Coulombic efficiency of 96.9 % after 2400 cycles at -50°C.

However, their practical performance is often hindered by sluggish Zn²⁺ diffusion, primarily due to the large hydrated ionic radius and strong electrostatic interactions. To address this, we present a polyanion-based cathode material, [Zn₁K₂]Fe₃(PO₄)₂(P₂O₇), that enables a reversible dual-ion intercalation mechanism involving both Zn²⁺ and K⁺. Compared to Zn²⁺, monovalent K⁺ interacts more weakly with the PO₄/P₂O₇ framework and desolvates more readily at the electrolyte–cathode interface, enabling the Zn²⁺/K⁺ dual-ion system to achieve faster kinetics than the Zn²⁺-only system. This leads to significantly enhanced power capability and structural reversibility under the AZIB system. The discharge capacity of [Zn₁K₂]Fe₃(PO₄)₂(P₂O₇) is 100.4 mAh g^-1 at C/5 (1C = 100 mA g^-1), corresponding to de/intercalation of 2 mol K⁺ and 0.5 mol Zn²⁺. Even at 5C, it maintains a capacity of 70 mAh g^-1, outperforming the Zn²⁺-only analogue Zn₂Fe₃(PO₄)₂(P₂O₇) (55 mAh g^-1). Galvanostatic intermittent titration technique measurements further confirm the enhanced ionic diffusion kinetics enabled by the Zn²⁺/K⁺ dual-ion system.
