Zusammenfassung:	An electrochemical apparatus includes a housing and an electrode assembly accommodated in the housing. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator wound together. The first electrode plate includes a first current collector having a first region and a second region; and a first active material layer disposed in the first region. The second region is provided at an end of the first current collector in a first direction to form a first tab. The second electrode plate includes a second current collector; at least two second tabs; and a second active material layer disposed on the second current collector. The at least two second tabs are connected to an end of the second current collector, the at least two second tabs being facing away from the second region in a first direction; the at least two second tabs are spaced apart in a winding direction of the electrode assembly and are integrally formed with the second current collector.
