Abstract
In various embodiments, provided are an electrode plate comprising a main body region and an isolation region, the isolation region is arranged on both sides of the main body 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, a method for preparing the electrode plate, a secondary battery, a battery module, and a battery pack. 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.
