Among these steps, the baking process before electrolyte filling is one of the key factors determining the final quality and safety of the battery.

[0003] Existing technology mainly involves placing the battery cells inside an oven and then arranging a heating mechanism inside the oven to regulate the temperature inside the oven and control the moisture content in the battery cells, reducing the moisture content inside the battery cells to an extremely low level, thus laying the foundation for subsequent processes.

[0004] However, the applicant has found that the prior art has at least the following problems: In existing technologies, when removing the baked battery cells, workers need to remove them one by one. However, the baked battery cells have a certain temperature, which not only makes the removal process slow but also may burn the workers. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a pre-filling baking mechanism for lithium batteries to solve the problems of slow cell removal speed and easy burns after baking.

[0006] Based on the above objectives, this utility model provides a pre-filling baking mechanism for lithium batteries, including a baking oven and a support frame. The baking oven has a top cover and a bottom cover hinged to the bottom. Multiple heating tubes are arrayed on the side wall of the baking oven.
