| 主权项 | 1. A secondary battery, comprising: a case with an internal space; at least one electrode assembly in the case, the electrode assembly including a separator between a positive electrode plate and a negative electrode plate; a current collector plate coupled to the electrode assembly, the current collector plate including an electrode terminal; a dielectric body with a through-hole on the current collector plate, the dielectric body having a first stepped portion, and the electrode terminal of the current collector plate protruding through the through-hole of the dielectric body; a gasket in the through-hole of the dielectric body, the gasket overlapping at least two different surfaces of the dielectric body, the gasket having a second stepped portion overlapping and coupled to the first stepped portion; and a cap plate coupled to an upper portion of the dielectric body. | ||
