Abstract (en)
[origin: US4724055A] Lithium metal is continuously prepared, in specially adapted electrolytic cell, by (i) continuously electrolyzing a mixture of molten salts including lithium chloride, said mixture comprising the medium of electrolysis, (ii) continuously withdrawing admixture of product lithium metal with said mixture of molten salts, and (iii) continuously discharging formed chlorine gaseous phase therefrom, wherein the medium of electrolysis is maintained at a temperature ranging from the melting point of said mixture of molten salts, at the eutectic composition thereof, to 400 DEG C., and said gaseous chlorine phase is maintained at a temperature not exceeding 300 DEG C.
