Abstract

This application discloses an electrochemical apparatus and an electric device. The electrochemical apparatus includes a first housing portion and a second housing portion of opposite polarities, an electrode assembly, and a first connector. The electrode assembly includes an electrode plate assembly, a first tab, and a second tab. A first electrode plate of the electrode plate assembly is located on a winding inner side relative to a second electrode plate. The first tab is connected to a first region of the first electrode plate. The first tab includes a second region connected to the first housing portion. The second tab is connected to a third region of the second electrode plate. The first connector is connected to the first housing portion, and includes a fourth region configured to be connected to an electric device. A winding length of the first region extending beyond the third region is less than one turn. An angle formed by rotating the third region to the first region around a winding center is θ, satisfying: 45° ≤ θ ≤ 135°. An angle formed by rotating the first region to the fourth region around the second region is α, satisfying: -60° ≤ α ≤ 45°. The electrochemical apparatus of this application is conducive to reducing an axial magnetic field at the end face, thereby reducing interference with the electric device.
