Abstract
An alkali salt composition free from hydroxides, melting at a temperature in the region of or greater than 180.degree., and usable in its molten state as a negative electrolyte for accumulators comprising an alkali metal negative electrode and an alkali alumina separator, contains an alkali metal amide, at least one alkali halide and an alkali hydride. It may also contain aluminium amide.
Claims8
An alkali salt composition free from hydroxide, usable in its molten state as an anode electrolyte for accumulators with an alkali metal negative electrode and with an alkali alumina separator, the said composition containing an alkali amide, at least one alkali halide, and an alkali hydride.
A secondary electrochemical cell having an alkali metal negative electrode, a positive electrode, an alkali alumina separator between said electrodes, and between the separator and the negative electrode a molten-salt electrolyte composition comprising an alkali amide, at least one alkali halide, and an alkali hydride.
