    摘要： The embodiments of the present disclosure relate to a battery cell, a battery and an electricity consuming device. The battery cell includes a shell, a pressure relief mechanism, an electrode assembly and an insulating member. The pressure relief mechanism is disposed on the shell. The electrode assembly is accommodated within the shell. The insulating member is accommodated within the shell, at least a portion of the insulating member is located between the pressure relief mechanism and the electrode assembly, and a portion of the insulating member located between the pressure relief mechanism and the electrode assembly is provided with a first weak portion. The insulating member can insulate and isolate the pressure relief mechanism from the electrode assembly, to reduce a risk of the pressure relief mechanism conducting positive and negative electrodes of the electrode assembly, and by providing the first weak portion on the insulating member, it can reduce obstruction of the insulating member to high-temperature and high-pressure substances when thermal runaway occurs in the battery cell, so that the pressure in the battery cell can be released timely, thereby improving safety.
