Abstract: A welding clamp for use in battery manufacturing is described. The welding clamp includes a plurality of clamping portions used to fit and clamp a case of a battery cell, the clamping portion includes a body portion and a connecting portion, and the connecting portion is detachably connected to the body portion; and a wear-resistant layer is connected to a surface of the connecting portion facing the case. In the process of welding the case and the end cover of the battery cell, through fitting and clamping the case by the clamping portion of the welding clamp, the clamping portion can play a position-limit role to the wall of the case to relieve the deformation of the case during the welding process, thereby improving the welding quality of the case and the end cover and thus improving the production quality of the battery cell.

Abstract: An air nozzle includes a housing and an airflow regulation apparatus. The housing includes a target air outlet and an air inlet. Air flow enters the housing through the air inlet and leaves the housing through the target air outlet. The airflow regulation apparatus is located at the target air outlet and is capable of moving between a first position and a second position. The airflow regulation apparatus exerts a greater resistance against the air flow in the first position than it exerts against the air flow in the second position. When the airflow needs to be reduced, the airflow regulation apparatus is regulated to the first position to increase the resistance against the air flow at the target air outlet. When the airflow needs to be increased, the airflow regulation apparatus is regulated to the second position to reduce the resistance against the air flow at the target air outlet.

Abstract: A method for detecting a qualified rate of a battery electrode sheet includes collecting a first weight corresponding to a to-be-detected electrode sheet, drying the to-be-detected electrode sheet in a drying apparatus for a preset duration and collecting a second weight corresponding to the dried to-be-detected electrode sheet, and determining a detection result of the to-be-detected electrode sheet based on a ratio of a drying difference to the second weight. The drying difference is a difference between the first weight and the second weight.

Abstract: A back roller includes a roller body and a wear-resistant layer. The roller body has an axis and a roll surface disposed around the axis. The wear-resistant layer covers the roll surface. Vickers hardness (H) of the wear-resistant layer is 800 HV≤H≤1400 HV. The roll surface is covered by the wear-resistant layer, and the Vickers hardness (H) of the wear-resistant layer is controlled to be between 800 HV and 1400 HV, so that the roll surface is effectively protected, and wear resistance of the roll surface is improved. In this way, the wear-resistant layer is in direct contact with a material during operation, thereby effectively reducing an abrasion loss on the roll surface and extending the service life of the roll surface.
