Rolled Alkali Metal Batteries and Production Process

Abstract

Provided is a rolled alkali metal battery wherein the alkali metal is selected from Li, Na, K, or a combination thereof. The battery comprises an anode, a cathode, an alkali metal ion-conducting separator electronically separating the anode and the cathode, and an alkali metal ion-containing electrolyte in ionic contact with the anode and the cathode, wherein the 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 the 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 the anode roll width and/or the cathode roll width direction is substantially perpendicular to the separator plane.
