Description

Technical Field

[0001] This utility model relates to a heating device for the side roller pressing of battery electrode tabs, belonging to the field of battery manufacturing technology. Background Technology

[0002] In battery manufacturing, electrode preparation is one of the key steps. Battery electrodes are composed of current collector foil with active materials coated on their surfaces at intervals, forming coated areas and uncoated tab areas. During the rolling process, due to the significant thickness difference between the coated areas and the tab areas, the coated areas are subjected to greater pressure than the tab areas. This can easily lead to uneven deformation between the two areas, inducing irregular wrinkles on the electrode, which may affect the conductivity and structural integrity of the electrode.

[0003] A ring-shaped heating roller and its control system for electrode rolling are disclosed in patent number CN117174814A. The roller includes a base and a rolling assembly mounted on the base. The rolling assembly includes an insulating sleeve that conforms to the coating area of ​​the electrode and a heating ring that conforms to the tab area of ​​the electrode. The rolling assembly also includes a heating element that provides heat to the heating ring and a conductive component that supplies power to the heating element. A sensor for detecting the temperature of the heating ring is also installed on the rolling assembly, and a temperature control component communicatively connected to the sensor is also included. This ring-shaped heating roller can independently and integrally complete the heating and rolling of the tab area. The heating unit is in close contact with the tab area of ​​the electrode, with no gaps, which greatly improves the ductility of the tab area and ensures the uniformity of the duct extension between the tab area and the coating area. This helps to avoid irregular wrinkles on the electrode and ensures the quality of electrode production.

[0004] The aforementioned patent integrates the heating ring into the rolling assembly, which directly contacts the tab side for heating and rolling. This fixes the heating equipment to a single production line, making it unsuitable for other production lines and unable to adjust the position of the heating device, resulting in low flexibility.
