Abstract
A method of preparing a metal sheet includes extruding a component along an extrusion axis. The component has a wall at least partially defining an interior region. The component includes a metal. The method further includes unfurling the wall to form a sheet precursor. The sheet precursor has a first thickness and a first transverse dimension. The method further includes rolling the sheet precursor along a rolling axis to form the metal sheet. The metal sheet has a second thickness perpendicular to the rolling axis. The second thickness is less than the first thickness. The second transverse dimension is parallel to the rolling axis. The second transverse dimension is greater than the first transverse dimension. In certain aspects, the metal includes lithium and the metal sheet is a lithium metal electrode.
