ELECTROCHEMICAL APPARATUS AND ELECTRONIC APPARATUS

An electrochemical apparatus includes an electrode assembly, a first tab, and a second tab. The electrode assembly includes a first electrode plate and a second electrode plate. The first electrode plate includes a first current collector. The second electrode plate includes a second current collector and a plurality of conducting strips, the conducting strips protrude from the second current collector in a first direction, the plurality of conducting strips are stacked in a thickness direction of the electrode assembly to form a collecting portion. The first tab includes a first portion, a second portion, and a third portion connected in sequence, the first portion is connected to the first current collector, the second portion is located outside the first current collector and disposed in a bent shape, the third portion extends out of the housing. The second tab is connected to the collecting portion and extends out of the housing.
