ABSTRACT:
The present invention concerns an electrode for an electrochemical primary cell, the electrode comprising a first electron conducting compound and a second ion conducting compound which consists of a sulfur-containing polymer with a repeating unit which contains a polyether, and which can contain an ionizable salt, characterized in that the backbone of said polymer contains bonds which render it capable of reversible oxidation and reduction. Preferably, said repeating unit is a polyether of the following type, containing two sulfur-containing ternary amine terminal groups: ##STR1## where R is a polyether selected from polyethylene oxide, polypropylene oxide, and their statistical, alternating, block and graft polyether copolymers.
