Quasi-solid-state electrolytes (QSSEs) have garnered significant attention due to combining the dynamic properties of liquid electrolytes and the high safety of solid-state electrolytes. However, the limited electrochemical stability window (ESW) of liquid electrolytes and the low conductivity of the polymer matrix seriously constrain practical application. Herein, an ant-nest electrospun amphiphilic polyurethane-based gel electrolyte (eAPG) with hydrophilic ion channels in an organic polyurethane matrix was synthesized by swelling electrospun amphiphilic polyurethane (eAP) membrane in NaClO₄-based trimethyl phosphate aqueous solution. The dynamically reconstructed hydrophilic ion channels enhance the Na⁺ transport rate five times compared to that in the polymer hydrophobic regions, which leads to a remarkable ion conductivity of 23.6 mS cm⁻¹. The transport of free water in QSSEs via the Grotthuss mechanism is intimately associated with the ESW, where the eAP cross-linked network diminished the activity of free water, resulting in an increased ESW of 2.3 V. Additionally, symmetric supercapacitors assembled by eAPG and activated carbon electrode exhibit 45.32 Wh kg⁻¹ at a power density of 0.933 kW kg⁻¹ with stable and long-term cycling. This rational electrolyte design strategy and remarkable electrochemical performance pave the way for the next generation of energy storage devices.

准固态电解质（QSSE）由于结合了液体电解质的动态特性和固态电解质的高安全性而受到了广泛关注。然而，液体电解质有限的电化学稳定性窗口（ESW）和聚合物基体的低电导率严重限制了实际应用。在此，通过在NaClO ₄基磷酸三甲酯水溶液中溶胀电纺两亲聚氨酯（eAP）膜，合成了有机聚氨酯基质中具有亲水离子通道的蚁巢电纺两亲聚氨酯基凝胶电解质（eAPG） 。与聚合物疏水区域相比，动态重建的亲水离子通道将Na ^{+传输速率提高了五倍，这导致了23.6 mS cm -1}的显着离子电导率。 QSSE 中自由水通过Grotthuss机制的传输与 ESW 密切相关，其中 eAP 交联网络减少了自由水的活性，导致 ESW 增加了 2.3 V。此外，由 eAPG 组装并激活的对称超级电容器碳电极在0.933 kW kg ^-1的功率密度下表现出45.32 Wh kg ^{-1 ，}并且具有稳定和长期的循环。这种合理的电解质设计策略和卓越的电化学性能为下一代储能设备铺平了道路。
