  "textContent": "Examples of the present application relate to a battery cell, a manufacturing method and a manufacturing system thereof, a battery, and a powered device. The battery cell includes: a shell, where the shell has a wall portion; an electrode assembly accommodated in the shell; and a pressure relief mechanism. The pressure relief mechanism is provided on the wall portion, the pressure relief mechanism includes a weak portion, a body portion, and a connecting portion. The weak portion is configured to be damaged when pressure inside the shell reaches a threshold so as to relieve the pressure. The body portion is located in a region defined by the weak portion. The connecting portion is located on an outer side of the weak portion and configured to connect the wall portion. The body portion protrudes relative to the connecting portion in a direction away from the electrode assembly. A first concave portion is formed in the pressure relief mechanism at a position corresponding to the body portion on a side facing the electrode assembly. The battery cell according to the examples of the present application can improve the safety of the battery cell.",
