    Abstract: An electrode assembly may include positive and negative electrode sheets, the positive and negative electrode sheets including positive and negative electrode current collectors and positive and negative electrode active material layers. The negative electrode sheet may be continuously bent and include a plurality of laminated segments and a plurality of bent segments for connecting the laminated segments; a plurality of the positive electrode sheets may be alternately laminated with the plurality of laminated segments in a first direction. An outermost positive electrode sheet may be a unilateral electrode having the positive electrode active material layer coated on an inner side rather than outer side of the positive electrode current collector thereof. The bent segment may be connected to an end of the laminated segment in a second direction; and the unilateral electrode may not extend beyond the adjacent bent segment.

    Abstract: The present disclosure provides an electrode assembly and a secondary battery. The electrode assembly includes a first electrode plate, a second electrode plate and a separator. The first electrode plate, the second electrode plate and the separator are wound to a flat structure, and the flat structure comprises a main region and corner regions, the corner regions are provided at two ends of the main region along a width direction of the main region. The first electrode plate and the second electrode plate each are wound to turns. A gap is provided between two adjacent turns of the first electrode plate, the gap includes a first gap and a second gap. The first gap corresponds to the corner region in position, the second gap corresponds to the main region in position, and a dimension of the first gap is larger than a dimension of the second gap.
