陶瓷/聚合物杂化固体电解质（HSEs）由于能够结合陶瓷电解质（CEs）和聚合物固体电解质（SPEs）的优点，克服两者的缺点，受到了广泛的关注。然而，HSE中CE和SPE的接口兼容性在很大程度上限制了它们的充分发挥。本文通过原位偶联反应制备了柔性陶瓷/聚合物HSE。陶瓷和聚合物通过强化学键紧密结合，解决了界面相容性问题，离子可通过高速公路快速传输。所制备的膜在室温下表现出9.83 × 10（-4）S cm（-1）的离子电导率和0.68的高Li+迁移数。这种原位偶联反应方法为解决界面相容性问题提供了一条有效途径。
Ceramic/polymer hybrid solid electrolytes (HSEs) have attracted worldwide attentions because they can overcome defects by combining the advantages of ceramic electrolytes (CEs) and solid polymer electrolytes (SPEs). However, the interface compatibility of CEs and SPEs in HSE limits their full function to a great extent. Herein, a flexible ceramic/polymer HSE is prepared via in situ coupling reaction. Ceramic and polymer are closely combined by strong chemical bonds, thus the problem of interface compatibility is resolved and the ions can transport rapidly by an expressway. The as-prepared membrane demonstrates an ionic conductivity of 9.83 x 10(-4) S cm(-1) at room temperature and a high Li+ transference numbers of 0.68. This in situ coupling reaction method provides an effective way to resolve the problem of interface compatibility.
