Microgel solid electrolyte membrane, preparation method and lithium battery

The invention belongs to the field of lithium battery preparation, and particularly relates to a microgel solid electrolyte membrane, a preparation method and a lithium battery. The microgel solid electrolyte membrane comprises a 3D tunnel, high-conductivity polymer molecules arranged on the 3D tunnel, lithium salt adsorbed on the high-conductivity polymer molecules, and electrolyte; a volume ratio of the electrolyte to the high-conductivity polymer molecules is (1 to 20) to 100. By infiltrating the electrolyte of a specific amount on the electrolyte membrane of a 3D tunnel structure, the electrolyte enters membrane holes of the 3D tunnel, no fluidity of the electrolyte is ensured, and the electrolyte forms a gel state; as the electrolyte exists, lithium ions move more smoothly, and the conductivity of the structure can be greatly improved relative a whole-solid-state membrane on the promise of ensuring safety performance. 本发明属于锂电池制备领域，具体涉及种微凝胶固态电解质膜、制备方法及锂电池。微凝胶固态电解质膜包括三维隧道、设置在所述的三维隧道上的高电导率聚合物分子、吸附在所述的高电导率聚合
