  "textContent": "An electrochemical apparatus includes a housing, an electrode assembly disposed inside the housing, a first tab group, and a first adapting piece electrically connected to the first tab group and extending out of the housing. The electrode assembly includes electrode plates comprising a first electrode plate and a second electrode plate, and a separator disposed between adjacent electrode plates. The first tab group includes a first connecting portion connected to the first adapting piece. The first tab group includes a plurality of first tabs connected to the first electrode plate and stacked on each other to form the first connecting portion. The first connecting portion includes a first portion. A thickness direction of the electrode assembly is defined as a first direction. In the first direction, the first portion is disposed between two adjacent layers of the electrode plates.",
