Abstract
A battery with many cavities that form tiny reaction zones having voids. During charging, lithium metal forms in each cavity on the anode current collector. The formation of lithium metal in each of the many thousands of small cavities that are isolated from each other prevents the buildup of significant quantities of lithium metal in one location. The combination of tiny reaction zones and voids allows lithium metal to form without stressing the structure of the battery cell.
