Abstract
Embodiments provide a battery cell including a porous membrane, the porous membrane including transformed semiconductor material. The porous membrane separates a first half-cell from a second half-cell of the battery cell. The porous membrane comprises channels allowing ions and/or an electrolyte to move between the first half-cell and the second half-cell.
