Abstract
An electrode assembly includes a negative electrode plate, a positive electrode plate, and a separator disposed between the negative electrode plate and the positive electrode plate. The negative electrode plate, the positive electrode plate, and the separator are wound together around a winding axis to form the electrode assembly. The negative electrode plate is a continuous negative electrode plate extending from a foremost winding end to a hindmost winding end along a winding direction. The positive electrode plate includes a continuous positive electrode plate disposed along the winding direction as well as a single-sheet positive electrode plate and/or a long-sheet positive electrode plate disposed along the winding direction apart from the continuous positive electrode plate.
