Abstract
A battery cell includes a housing, an electric terminal disposed on the housing, and an electrode assembly accommodated in the housing. The electrode assembly includes a main body portion and a tab extending out of an end face of the main body portion and including a first connecting portion configured to be connected to the electrode terminal and a second connecting portion configured to be connected to the main body portion. Along a length direction of the end face, at least part of the first connecting portion exceeds the second connecting portion. As the first connecting portion exceeds the second connecting portion in the length direction of the end face, the connectable range of the first connecting portion in the length direction of the end face can be expanded, facilitating direct connection of the first connecting portion with the electrode terminal.
