a battery cell includes an electrode assembly, a first electrode terminal, and a second electrode terminal. The electrode assembly includes a body portion, where a first tab, a second tab, and an auxiliary tab are led out of the body portion. The first tab and the auxiliary tab are both electrically connected to the first electrode terminal, and the second tab is electrically connected to the second electrode terminal. The first tab and the auxiliary tab are both electrically connected to the first electrode terminal to increase a current flow area of the tab electrically connected to the first electrode terminal.
