Roll-type alkali metal batteries are provided wherein the alkali metal is selected from Li, Na, K, or combinations thereof. The cell includes an anode, a cathode, an alkali metal ion conductive separator that electronically separates the anode and the cathode, and an alkali metal ion-containing electrolyte in ionic contact with the anode and the cathode, the anode being a length of an anode roll, A cathode comprising a wound roll of anode active material having an anode roll width and an anode roll thickness, and/or the cathode having a cathode roll length, a cathode roll width, and a cathode roll thickness. Including a wound roll of active material, the direction of the anode roll width and/or cathode roll width is substantially perpendicular to the plane of the separator.
