Abstract
The present application relates to a secondary battery, a battery module and an apparatus. The secondary battery includes an electrode assembly and a casing. The electrode assembly includes a main body portion and a tab portion, the tab portion extending out from the main body portion along an end of the main body portion and including an outer peripheral surface. The casing includes an accommodating hole for accommodating the electrode assembly. The casing includes a limiting protrusion. The outer peripheral surface extends around an axis of the accommodating hole. The limiting protrusion protrudes toward the tab portion and presses against the outer peripheral surface of the tab portion. The limiting protrusion is adapted to limit a position of the tab portion. The secondary battery provided by the present application can reduce the possibility of fatigue fracture of the adapting piece.
