The invention provides a solid electrolytic film suitable for online monitoring equipment in an extreme environment and a preparation method and application of the solid electrolytic film. The preparation method comprises the following steps: preparing a hollow structure PS (ZIF-8 core-shell particle with a core-shell structure by taking polystyrene particles as a template agent, introducing lithium salt into the core-shell particle to obtain an H-ZIF-8 composite material, then adding the H-ZIF-8 composite material into a polyether polyurethane matrix to obtain a solid electrolyte membrane, and assembling the solid electrolyte membrane into a power supply device, so that the low-temperature performance of the solid electrolyte membrane is greatly improved. Therefore, the problem that the power supply device in the on-line monitoring equipment cannot be normally used at low temperature is effectively solved, and the low-temperature reliability of the on-line monitoring equipment is improved. 本发明提供的一种适用于极端环境下在线
