摘要： The embodiment of the present application relates to the technical field of batteries. Provided are a battery cell, a battery, a power consumption apparatus, and a method and an apparatus for manufacturing the battery cell. The battery cell comprises a shell, an electrode assembly, an end cover and a current collecting member. The electrode assembly is accommodated in the shell, and the electrode assembly comprises a main body part and a first lug. The end cover covers an opening of the shell, and the end cover is provided with a liquid injection hole. The current collecting member is accommodated in the shell and located on the side of the end cover facing the main body part, and the current collecting member is configured to connect the first lug and the end cover so as to achieve electric connection between the end cover and the lug. The current collecting member is provided with a first center hole and a flow guide channel, the first center hole and the liquid injection hole are oppositely arranged, and the flow guide channel is configured to allow at least part of electrolyte entering the battery cell from the liquid injection hole to enter the main body part. The electrolyte entering the battery cell from the liquid injection hole can more easily permeate into the electrode assembly, thereby improving the liquid injection efficiency and improving the permeation effect of the electrolyte on the electrode assembly.
