Abstract
An Electrolytic cell having a separator positioned between a positive electrode and a negative electrode is disclosed in which the separator is a moulding of polymer material derived from a particulate polymer material having a polar graft-copolymerized surface. The separator may be deposited as a coherent film of the surface of an electrode by sintering the particulate material into a coating around the electrode using heat and/or pressure. Alternatively a shaped article such as a case, envelope, sheet film or the like may be prepared and used to wrap around or encase an electrode.
