1. A rolled alkali metal battery wherein said alkali metal is selected from Li, Na, K, or a combination thereof; said battery comprising an anode, a cathode, an alkali metal ion-conducting separator electronically separating said anode and said cathode, and an alkali metal ion-containing electrolyte in ionic contact with said anode and said cathode, wherein said anode contains a wound roll of an anode active material having an anode roll length, an anode roll width, and an anode roll thickness and/or said cathode contains a wound roll of a cathode active material having a cathode roll length, a cathode roll width, and a cathode roll thickness and wherein said anode roll width and/or said cathode roll width is substantially perpendicular to said separator and wherein said wound roll of anode active material has an edge surface in close physical contact with said separator and said wound roll of cathode active material has an edge surface in close contact with said separator, and wherein said wound roll of anode active material is supported by an anode current collector and/or said wound roll of cathode active material is supported by a cathode current collector.
