The present invention relates to a method and device for preparing an ultrathin metal lithium foil. With regard to the problems of lithium preparation processes in the prior art having a high lithium preparation reaction temperature, a low lithium recovery rate, low purity in collected lithium foils, a complicated process operation, etc., the present invention provides a method for preparing an ultrathin metal lithium foil, wherein firstly, a complex lithium salt is prepared, the complex lithium salt and a reducing agent are then subjected to a vacuum thermal reduction reaction so as to generate a metal vapor, the metal vapor is then subjected to vacuum distillation, and finally, vacuum evaporation is used to prepare the ultrathin metal lithium foil of the present invention. In the present invention, by precisely regulating and controlling conditions such as the formulation of the complex lithium salt, the thermal reduction reaction temperature, the temperature of a distillation device, the vacuum degree, materials and the reducing agent, vacuum reduction, vacuum distillation and vacuum evaporation are continuously performed, and lithium preparation, distillation purification, and evaporation can thus be continuously performed, thereby improving the efficiency of the production of the ultrathin metal lithium foil and saving on preparation costs.
