Abstract: In various embodiments, provided are an electrode plate, a method for preparing the same, a secondary battery, a battery module, and a battery pack comprising a main body region and an isolation region, where the isolation region is arranged on both sides of the main body region along a width direction of the electrode plate, the isolation region is provided with an insulating strip coating, and the main body region is provided with an active material layer. An outer edge of the active material layer is confined to a junction between the main body region and the isolation region, and a contact angle between a slurry forming the active material layer and the insulating strip coating is more than 90°, thereby improving the problem of diffusion of the active material slurry along the width direction of the electrode plate, and reducing a defective rate of the electrode plate.

Abstract: A coating shim and a coating device, for applying a first slurry and a second slurry to an object to be coated are provided. The coating shim includes: a first flow channel for applying the first slurry to the object to be coated to form a first coating layer; and a second flow channel for applying the second slurry to the object to be coated to form a second coating layer. The first flow channel has a first slurry outlet at a first end face of the shim facing the object to be coated, the second flow channel has a second slurry outlet at the first end face, and the first slurry outlet and the second slurry outlet are configured to partially overlap in a thickness direction of the shim, such that the first coating layer and the second coating layer partially overlap in the thickness direction of the shim.

Abstract: A strip diverting mechanism includes a negative pressure unit and an air discharge unit. The negative pressure unit and the air discharge unit are arranged opposite each other, and a gap through which a strip passes is formed between the negative pressure unit and the air discharge unit. The negative pressure unit is configured to provide a suction force to the strip and the air discharge unit is configured to provide a repulsive force to the strip, to prevent the strip from contacting the negative pressure unit and the air discharge unit.

Abstract: Provided are an electrode plate drying device and a coating device, and relates to the technical field of batteries. The electrode plate drying device includes an oven, a first deflector roll, and a second deflector roll. The oven is configured to dry an electrode plate. The first deflector roll and the second deflector roll are disposed in the oven. The electrode plate winds around the first deflector roll and the second deflector roll. Positions of the first deflector roll and/or the second deflector roll in the oven are tunable so as to adjust a movement distance of the electrode plate in the oven.
