Abstract: An electrochemical cell that may include a cathode sheet; a cathode tab that extends from the cathode sheet; an anode sheet; an anode tab that extends from the anode sheet, the second direction differs from the first direction; one or more separator sheets; and a first electrical connecting unit. The cathode sheet, the anode sheet and the one or more separator sheets are wound around a common axis to form multiple windings; wherein the one or more separator sheets separate between the anode sheet and the cathode sheet. The first electrical connecting unit mechanically and electrically contacts a first portion of a first electrode tab, the first portion belongs to a first winding of the multiple windings; wherein the first electrode tab is one of the anode tab and the cathode tab.
