Abstract: An electrochemical cell that includes (i) a cathode tabs electrical coupler; (ii) an anode tabs electrical coupler; and (iii) a stack that is rolled about an axis, wherein the stack includes multiple instances of: (a) a cathode sheet; (b) a cathode tab that extends from the cathode sheet at a first direction; (c) an anode sheet, (e) an anode tab that extends from the anode sheet at a second direction, the second direction differs from the first direction; and (f) one or more separator sheets. Multiple cathode tabs of the multiple instances are coupled in parallel to each other by the cathode tabs electrical coupler. Multiple anode tabs of the multiple instances are coupled in parallel to each other by the anode tabs electrical coupler.
