Solid-state zinc-air batteries (SZABs) are regarded as a promising energy source for next-generation wearable electronic devices due to their high theoretical energy density and reliability. However, practical development of solid-state zinc-air batteries is hindered by the low specific areal capacity and poor contact between solid-state electrolyte and electrode caused by zinc passivation and electrolyte aging. Herein, we report a new strategy for optimizing the solid-state electrolyte/electrode interface coupling by combining porous zinc electrode and thermal-sensitive solid-state electrolyte F127 to improve the areal-capacity of solid-state zinc-air batteries. The porous Zn anode prepared by zinc electrodeposition on the zinc substrate is used to alleviate zinc passivation and improve the specific area capacity of SZAB. In addition, to enhance the contact between the solid-state electrolyte and the zinc anode, the F127 surfactant is selected as the solid-state electrolyte due to its fluidity at low temperatures. Benefiting from the porous structure and excellent contact, the SZAB using porous zinc anode and the solid-state electrolyte F127 exhibits high areal capacity of 133 mAh cm⁻² at the current density of 4 mA cm⁻², which is 100 times higher than that of the solid zinc-air battery using zinc foil as the anode. Moreover, the results show that the use of porous zinc electrodes is conducive to achieving high current discharge, which is critical for the practical application of solid-state zinc-air batteries.

固态锌空气电池（SZAB）由于其高理论能量密度和可靠性而被认为是下一代可穿戴电子设备的有前途的能源。然而，由于锌钝化和电解液老化导致固态锌-空气电池的比表面积低和与电极接触不良，阻碍了固态锌-空气电池的实际发展。在此，我们报告了一种通过结合多孔锌电极和热敏固态电解质 F127 来优化固态电解质/电极界面耦合的新策略，以提高固态锌空气电池的面积容量。通过在锌基体上电沉积锌制备的多孔锌阳极，用于缓解锌钝化，提高 SZAB 的比表面积容量。此外，为了增强固态电解质与锌阳极之间的接触，选择 F127 表面活性剂作为固态电解质，因为它在低温下具有流动性。受益于多孔结构和良好的接触，使用多孔锌阳极和固态电解质 F127 的 SZAB 表现出 133 mAh cm 的高面积容量^-2在 4 mA cm ^-2的电流密度下，比使用锌箔作为阳极的固体锌空气电池高 100 倍。此外，结果表明，多孔锌电极的使用有利于实现大电流放电，这对固态锌空气电池的实际应用至关重要。
