  • ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS
    Publication number: 20230170592
    Abstract: An electrode assembly includes a first electrode plate and a second electrode plate. The first electrode plate includes a first body portion and a tab. The first body portion has a first end portion in a first direction. The tab is coupled to the first end portion. The second electrode plate includes a second body portion and an insulation portion coupled to the second body portion. The first body portion and the second body portion are stacked in a stacking direction perpendicular to the first direction. The second body portion has a second end portion close to the tab in the first direction. The insulation portion covers at least part of the second end portion so as to separate the tab from the second end portion when the tab is bent.
