Abstract

This application discloses an electrode plate, an electrochemical device, and an electrical device. The electrode plate includes a base portion and a tab. The base portion includes a first edge connected to the tab. The tab includes an extension portion and a connecting portion. Along a length direction of the electrode plate, the extension portion includes a first side edge and a second side edge disposed opposite to each other. The connecting portion includes a third side edge and a fourth side edge disposed opposite to each other. A first connection point is formed between the third side edge and the first side edge. A third connection point is formed between the third side edge and the first edge. A second connection point is formed between the fourth side edge and the second side edge. A fourth connection point is formed between the fourth side edge and the first edge. An extension line of the first side edge intersects the first edge at a first intersection point. An angle between a ray from the first intersection point to the first connection point and a ray from the first intersection point to the fourth connection point is α<1>, satisfying: α<1> < 90°. With a line of connection from the first connection point to the third connection point serving as a first reference line, the connecting portion includes a first reinforcing region defined by the third side edge and the first reference line. This application alleviates the problems of bending and tearing of the tab.
