The invention relates to the field of lithium battery manufacturing, in particular to a lithium battery fluorine-containing poly compound vacuum drying system which comprises a vacuum drying tank. The outer wall of the vacuum drying tank is provided with a feeding pipe, a discharging pipe and a vacuum extraction pipe, the top of the feeding pipe is provided with a feeding hopper, the magnetic substance content and foreign matter of the fluorine-containing poly-compound cannot be increased, the quality and the overall performance of the fluorine-containing poly-compound are improved, and in the whole drying process, the drying efficiency is greatly improved. Compared with the prior art, the fluorine-containing poly-compound does not rub with the outside and does not break the fluorine-containing poly-compound, the quality and the overall performance of the fluorine-containing poly-compound are further improved, nitrogen protection drying is not needed in the whole drying process, energy consumption is low, and
