1. Secondary electrochemical generator employing a non-aqueous electrolyte, characterized in that its positive active material is chosen out of the group formed by iron hexacyanoferrate, by the compounds derived therefrom by at least partial replacement of the iron by other elements of the groups 4A, 5A, 6A, 7A and 8 of the periodic table and which have at least two stable oxidation states other than zero, and mixtures of these compounds. |
