Electrochemical cells whose the electrolytical media consist of anhydrous ammoniates of salts of a metal identical to the anode metal

摘要

The present invention relates to novel electrochemical cells whose electrolytical media consist of anhydrous ammoniates of salts of a metal identical to the anode metal. According to the present invention, the electrochemical cell of the type comprising an anode consisting of a highly reducing metal M% or of an alloy of highly reducing metals M%, a cathode consisting of a reducible material and an essentially anhydrous solid or liquid electrolyte, the said electrolyte consisting of at least one ammoniate of at least one salt X of a cation of a metal M_ at least as reducing as the metal(s) M% of the anode, according to one of the claims of the main patent No. 82 10488, characterised in that the said ammoniate is prepared in the anhydrous state by reacting the said metal cation salt, M_X, in liquid ammonia in the presence of an alkali metal amide MNH2.
