Bernard, L; Le Mehaute, A; Lelieur, J P

An electrochemical cell which has a negative electrode including an alkali or alkali-earth metal dissolved in liquid ammonia, a positive electrode, an electrolyte, and a separator. The positive electrode is constituted by a solution in ammonia of a chalcogen or of a chalcogenide or of an emulsion or suspension in ammonia of a solid compound suitable for intercalating the metal of the negative electrode. Said electrolyte includes a solution of an iodide of an alkali or alkali-earth metal. The invention is used in the field of reversible high-power electric cells operating at low temperatures.
