Flexible zinc-ion hybrid capacitors (ZIHCs) based on hydrogel electrolytes are an up-and-coming and highly promising candidate for potential large-scale energy storage due to their combined complementary advantages of zinc batteries capacitors. However, the freezing induces a sharp drop in conductivity mechanical property with tremendous compromise interfacial adhesion, thereby severely impeding low-temperature application such flexible ZIHCs. To achieve ZIHCs excellent adaptability, antifreezing self-adhesive polyzwitterionic electrolyte (PZHE) is engineered via self-catalytic nano-reinforced strategy, affording unparalleled robust together superhigh strength over broad temperature ranging from 25 -60 °C. Meanwhile, water-in-salt-type PZHE filled ZnCl2 can provide ion migration channels enhance reversibility Zn metal electrodes, thus greatly reducing side reactions extending cycling life. With distinctive integrated merits water-in-salt type PZHE, as-built deliver high-level density 80.5 Wh kg-1, desired specific capacity 81.5 mAh g-1, along long-duration lifespan (100 000 cycles) 84.6% retention at -40 °C, even outperforming state-of-the-art room temperature. More encouragingly, extraordinary temperature-adaptability both electrochemical performance under severe challenges achieved extremely low Noticeably, ZIHC also capable operating ice-water bath vacuum. It believed that this strategy makes contributions inspire design high-performance PZHEs fields wearable electronics work cold environments.
