PERFECTIONNEMENTS RELATIFS AUX ELEMENTS ET BATTERIES ELECTRIQUES

摘要

An electric cell of the kind in which the electrochemical reactants are liquid sodium as negative active material (anode) and liquid sulphur material as positive active material (cathode) and anode and cathode compartments are separated by a solid electrolyte which is a sodium ion conductor. The cell is assembled in the discharged state and the cathode compartment initially contains sodium poly-sulphide encapsulated in elemental sulphur.
