ABSTRACT:
Sensitive material, e.g. lithium electrode material, is provided with a protective layer of fluid-impermeable material, which is subsequantly rendered permeable by altering its physical structure, e.g. by perforation, without altering its composition. The permeable material can act, for example, as an electrode separator when the resulting article is assembled into an electrolytic cell, and the protected material can be processed, e.g. rolled into thin sheets, and conveniently fed to automatic assembly apparatus.
