The invention provides a lithium bis (trifluoromethylsulfonyl) imide drying device, and relates to the technical field of lithium ion battery manufacturing. The lithium bis (trifluoromethylsulfonyl) imide drying device comprises a vacuum drying cabin. The outer curved side face of the rear end of the vacuum drying cabin is fixedly connected with a first limiting ring through welding. A second limiting ring is arranged behind the first limiting ring. The top of the curved side face of the vacuum drying cabin is fixedly connected with a feeding pipe. An anti-leakage valve is arranged in the feeding pipe through flange connection. An inclined lifting structure is arranged at the rear end of the vacuum drying cabin. The inclined lifting structure comprises a bearing hoop, a fixing hoop and bottom shaft oscillation pieces, the oscillation pieces can drive the vacuum drying cabin to vibrate through ultrasonic high-frequency vibration, moisture in lithium bis (trifluoromethylsulfonyl) imide liquid in the drying proc
