Abstract: Provided are a defect detection method and apparatus, and a computer-readable storage medium. Specifically, the method includes: obtaining a to-be-detected image; obtaining a feature map of the to-be-detected image based on the to-be-detected image, where the feature map of the to-be-detected image includes a feature map of spatial position coordinate information; and performing defect detection on the to-be-detected image based on the feature map of the to-be-detected image. By modifying a neural network structure of defect detection and extracting the feature map of spatial position coordinate information during the detection, this application makes the neural network for use of defect detection sensitive to a spatial position, thereby enhancing sensitivity of a detection neural network to the spatial position, and in turn, increasing accuracy of detecting some specific defect types by the detection neural network, and increasing accuracy of defect detection.

Abstract: The present application provides a secondary battery including a first terminal component, a second terminal component, a cap plate, an electrode component and a resistance element. One of the first and second terminal components is electrically connected to the cap plate through the resistance element, while the other is insulated from the cap plate. The first terminal component includes a connecting plate and a turnable plate, and the connecting plate is attached to the turnable plate. When the secondary battery is in a normal state, a first electrode plate is electrically connected to the connecting plate through the turnable plate, and the second electrode plate is electrically connected to the second terminal component. When a pressure inside the secondary battery exceeds a reference pressure, the turnable plate can turn over to cut off an electrical connection between the turnable plate and the first electrode plate.
