Abstract
Continuous metal electrodes are protected by non-porous fluid-impermeable material which is convertible to a fluid-permeable (porous) state, enabling the protective material to act as an electrode separator after the conversion. Conversion by contact with the non-aqueous fluid in a lithium cell is preferred, using strips of lithium protected with a blend of polyethylene and polyethylene oxide, the latter being extractable by the cell liquids.
