Abstract

A conductive block and a detection mechanism are provided. The conductive block (1) is used for pressing electrode tabs (102) of an electrode assembly (100) for withstand voltage testing, where the conductive block (1) includes a transition surface (3), and the transition surface (3) matches an inclined surface formed after the electrode tabs (102) are pressed. Withstand voltage testing on the electrode assembly (100) through the conductive block (1) is conducted, where the transition surface (3) matches the inclined surface formed after the electrode tabs (102) are pressed, reducing the risk of stress concentration causing damage to the electrode tabs (102) due to the conductive block (1) abutting the electrode tabs (102) during pressing, as well as the risk of stress concentration causing damage to the electrode tabs (102) due to the conductive block (1) abutting the electrode tabs (102), and also reducing the risk of creases generated during pressing causing the electrode tabs (102) to lift, thereby improving the reliability of the electrode assembly (100), and thus improving the reliability of battery cells (105) and batteries (110).
