A battery cell includes an electrode extraction portion configured to extract electric energy, and an electrode assembly comprising a main body and a tab. The tab includes a transition portion and a connection portion, with the connection portion bent relative to the transition portion. The transition portion connects the main body to the connection portion, and the connection portion is configured for connection to the electrode extraction portion. An insulating member is disposed on an inner side of the bent tab and includes a first insulator fixed to the main body, a third insulator fixed to the connection portion, and a second insulator disposed between the first and third insulators. At least a portion of the transition portion is not fixed to the insulating member. A battery and an electric apparatus incorporating the battery cell are also disclosed.
