ABSTRACT:
Electrochemical device comprises a negative compartment and a positive compartment. The negative compartment contains a negative medium formed at least in part of a liquid metal, and the negative and positive compartments are separated by a solid separator which is capable of being traversed by ions of the metal and is a conductor of said ions. The device is characterized by the fact that the negative compartment contains a solid electrolyte which is a conductor of these ions, this electrolyte separating the negative compartment into two regions--on the one hand, a negative region containing the negative medium and a negative collector, and, on the other hand, an intermediate region, located between the separator and the electrolyte, containing an intermediate medium formed at least in part of the metal in liquid state and/or of at least one salt of the metal in dissolved or molten state.
