This utility model discloses an aluminum foil anti-corrosion coating application device, including a frame. A transverse movement mechanism is fixedly installed on the inner side of the frame. A fixed crossbar is rotatably installed on the top of the transverse movement mechanism. Fixed frames are fixedly installed at both ends of the fixed crossbar. A flipping frame is slidably installed on the inner side of the fixed frame. A fixed support plate is fixedly installed on the top of the flipping frame. A fixed block is fixedly connected to one side of the top of the fixed support plate. This utility model adopts a structural design in which the distance between the scraper and the rotating roller can be flexibly adjusted. By scraping away the amount of coating liquid carried by the coating roller, the thickness of the anti-corrosion coating on the aluminum foil surface can be adjusted, ensuring the continuity of the coating liquid supply, ensuring the uniformity and smoothness of the coating liquid on the aluminum foil surface, improving the quality and efficiency of the anti-corrosion coating process, and providing convenience for users.

The application relates to the technical field of batteries, and discloses a battery cell and a battery pack. The battery cell comprises a shell with an open end, the open end of the shell forms a first end face, a cover plate assembly comprises a cover plate body, the cover plate body comprises a body part and a boss, the boss is connected to one side of the body part in the Z direction, the body part is lapped on the first end face, the boss extends into the inner cavity of the shell, and the boss is arranged in a spaced mode with the shell; a guide ring is sleeved on the boss and clamped between the boss and the shell, and the height of the guide ring in the Z direction is greater than the thickness of the boss in the Z direction. By sleeving the guide ring on the outer circumferential side of the boss, the area where the guide ring is in contact with the inner wall of the shell forms a support area, the setting of the guide ring increases the support height of the inner wall of the shell, improves the support stability, reduces the strain of the heat affected zone without increasing the thickness of the cover plate body, avoids the abnormal problem that the welding heat affected zone of the shell is prone to cracking under the action of a large fatigue stress, and improves the safety of the battery cell.
