The rapid development of wearable electronics demands for high-safety and stretchable lithium-ion batteries which are closer to the human skin, then accelerating the requirement for all-solid-state electrolytes with high stretchability and ion conductivity. Here, we proposed a decoupling strategy to effectively overcome the theoretical tradeoff between mechanical properties and ion conductivity of all-solid-state polymer electrolytes. The prepared stretchable all-solid-state polymer electrolyte (SSPE) via UV polymerization exhibits outstanding elastic tensile properties with elongation at break around 160.38%. The most interesting thing is that the SSPE membrane maintain high ion conductivity under external stress, the ion conductivity is 4.65 × 10⁻⁴ S cm⁻¹ (0% strain) and 4.24 × 10⁻⁴ S cm⁻¹ (75% strain) at room temperature. In addition, the SSPE membrane shows an excellent electrochemical stability window up to 5.2 V (vs. Li⁺/Li). The practicality of the SSPE was also investigated, including cell performance, deformation tests and destruction experiments. Therefore, the reported design of decoupling dual-function networks provides a promising approach for creating all-solid-state polymer electrolytes with high safety for stretchable energy storage applications.

可穿戴电子产品的快速发展需要更接近人体皮肤的高安全性和可拉伸锂离子电池，从而加速了对具有高可拉伸性和离子导电性的全固态电解质的需求。在这里，我们提出了一种去耦策略，以有效克服全固态聚合物电解质的机械性能和离子电导率之间的理论权衡。通过紫外线聚合制备的可拉伸全固态聚合物电解质（SSPE）表现出优异的弹性拉伸性能，断裂伸长率约为 160.38%。最有趣的是，SSPE 膜在外部应力下保持高离子电导率，离子电导率为 4.65 × 10 ^-4  S cm ^-1（0% 应变）和 4.24 × 10^-4  S cm ^-1 (75% 应变) 在室温下。此外，SSPE 膜显示出优异的电化学稳定性窗口，最高可达 5.2 V（相对于Li ⁺ /Li）。还研究了 SSPE 的实用性，包括电池性能、变形测试和破坏实验。因此，所报道的解耦双功能网络设计为创建具有高安全性的全固态聚合物电解质用于可拉伸储能应用提供了一种有前景的方法。
