Abstract

An electrochemical apparatus (100) and an electric device are provided. The electrochemical apparatus (100) includes: a housing (1), a first feedthrough member (7), an electrode assembly (2), and a first tab (3). The housing (1) is provided with an accommodating cavity (14). The electrode assembly (2) is accommodated in the accommodating cavity (14). The housing (1) includes a first side plate (131). The first feedthrough member (7) runs through the first side plate (131), and the first feedthrough member (7) is insulated from the first side plate (131). The first tab (3) is connected to the electrode assembly (2). The electrochemical apparatus (100) further includes a first adapter (5), where the first adapter (5) is accommodated in the accommodating cavity (14). The first tab (3) is provided with a first bending groove (324). One end of the first adapter (5) is connected to a groove wall of the first bending groove (324), and another end of the first adapter (5) is electrically connected to the first feedthrough member (7). Along a thickness direction of the first side plate (131), a projection of the first tab (3) does not overlap with a projection of the first feedthrough member (7). The above manner is conducive to reducing a dimension of the electrochemical apparatus (100) in a width direction. When the dimension of the electrochemical apparatus (100) in the width direction remains unchanged, more space can be left for the electrode assembly (2), which is conducive to increasing the energy density of the electrochemical apparatus (100).
