Zusammenfassung:	The present application relates to an end cap assembly (21), a battery cell (20), a battery (100), and an electric apparatus. The end cap assembly comprises an end cap (21a), a first sealing member (21b), and a second sealing member (21c). The end cap (21a) comprises a cap body (a1). The cap body (a1) comprises a cap portion (a11) and a liquid injection boss (a12), and is provided with a liquid injection hole (k) penetrating through the cap portion (a11) and the liquid injection boss (a12). The first sealing member (21b) performs blocking in the liquid injection hole (k). The second sealing member (21c) is provided with a first sealing portion (c1) and a second sealing portion (c2) that are connected to each other. The first sealing portion (c1) covers the side of the first sealing member (21b) facing away the interior of the battery cell (20). The second sealing portion (c2) is bent towards the interior of the battery cell (20) relative to the first sealing portion (c1) and is in sealed connection with the peripheral side wall (w) of the liquid injection boss (a12).
