Abstract
An electrode assembly includes first and second electrode plate having opposite polarities, and a separator separating the first and second electrode plates. The first electrode plate includes two first stack sections and a bend section connecting the first stack sections and including a guide portion configured to guide the bend section to bend during production. The second electrode plate includes a second stack section disposed between the first stack sections. The separator includes two separation sections each disposed between the second stack section and one first stack section. Thickness Da of each first stack section, thickness Dc of the second stack section, and thickness Ds of each separation section in a stacking direction of the first stack sections, and a dimension w of the guide portion in a bending direction of the bend section satisfy: Dc+2Ds≤w≤2×(Dc+2Ds+Da).
