Abstract: An electrode assembly includes: a first electrode plate layer, a first separator, a second electrode plate layer and a second separator. A winding start end of the first electrode plate layer, a winding start end of the first separator, and a winding start end of the second separator are substantially aligned with one another. The first electrode plate layer includes a first insulating section and a first electrode plate connected to each other, and the end of the first insulating section away from the first electrode plate is the winding start end of the first electrode plate layer. Along a winding direction of the electrode assembly, the winding start end of the second electrode plate layer is substantially aligned with the winding start end of the first electrode plate layer, or is located downstream of the winding start end of the first electrode plate layer.

Abstract: A winding device includes a pair of outer pins oppositely arranged in a first direction with a periphery for an electrode assembly to wind around, adjusting members configured to reciprocate in a second direction perpendicular to the first direction to drive the pair of outer pins to move away from or close to each other to increase or reduce a distance between the pair of outer pins, a pair of inner pins arranged oppositely in the first direction between the pair of outer pins and configured to move independent of the adjusting members to clamp or release the electrode assembly, and an elastic returning member configured to apply an elastic force in the first direction to at least one of the pair of inner pins such that the pair of inner pins have a tendency to be close to each other.
