  "textContent": "An electrochemical apparatus, including a first housing, a first connector connected to the first housing, 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. The first tab is connected to a first region of the first electrode plate, and includes a second region connected to the first housing. The second tab is connected to a third region of a second electrode plate. The first connector includes a fourth region. 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, 45°≤θ≤135°. An angle formed by rotating the first region to the fourth region around the second region is α, −60°≤α≤45°.",
