ABSTRACT:
An electrochemical secondary cell using lithium and a liquid organic electrolyte, the cell being of the cylindrical or prismatic type, wherein its separator comprises a microporous film of polyolefin next to the lithium anode and a film of cross-linked polymer that swells in the electrolyte and which applies pressure against the electrodes. The cross-linked polymer may be an ion conducting polymer including a polyether with two terminal amine functions.
