An improved electrolyte phase for use in high temperature primary and secondary batteries of the thermally or electrically regenerative type. The improved electrolyte phase is made up of a support matrix, which is solid or paste-like at the operating conditions for the battery, and the electrolyte for the battery immobilized and incorporated in the support matrix. The support matrix is made up of an inert alkali metal salt such as alkali metal aluminate. The electrolyte may be an alkali metal halide or mixtures of alkali metal halides. |
