Abstract
Disclosed herein are a battery cell housing, a battery cell, a battery, and an electric device. The battery cell housing defines a cavity configured to accommodate an electrode assembly, and the battery cell housing includes a first housing and a second housing. The first housing is electrically connected to a first tab of the electrode assembly. The second housing is fixed to the first housing in an insulated manner. The second housing is electrically connected to a second tab of the electrode assembly and the second tab is different from the first tab in polarity. The first housing includes a bulge electrically connected to the first tab, and the bulge extends in a direction approaching the second housing. Therefore, there is no need to provide a hole in the battery cell housing, thereby rendering the battery cell housing more integral.
