Abstract
A cell includes an electrode assembly, a pin assembly, and a cell house. The electrode assembly includes a central hole, at least one positive electrode, at least one negative electrode, and at least one diaphragm separating the at least one positive electrode from the at least one negative electrode. The at least one positive electrode, the at least one negative electrode and the at least one diaphragm are disposed around the central hole in a spiral winding manner. The pin assembly is disposed in the central hole for polarity separation. The pin assembly includes a housing including an axial through hole; the housing is partially or fully disposed in the central hole. The pin assembly further includes an insulating part for separating the polarity of the cell and at least one electrode lead. The cell house is hermetically connected to the housing.
