Abstract
A battery cell includes an electrode assembly and a housing accommodating the electrode assembly. The electrode assembly includes a first electrode plate and a second electrode plate. The first electrode plate includes a current collector, a connecting piece, and a tab. The current collector includes a plurality of stacked flat portions. A fixed end of the connecting piece is connected to one of the flat portions. A free end of the connecting piece is disposed toward the flat portion. The free end is flexibly bendable against the current collector. A first end of the tab is fixed to the connecting piece, and a second end of the tab is disposed beyond the flat portion.
