Electrolyte materials, thermal battery components, and thermal batteries for intermediate temperature applications

摘要

A eutectic formulation of KOH and NaOH is used as an electrolyte or an electrolyte-separator. An anode, and/or a cathode can contain the eutectic formulation of KOH and NaOH. A battery can contain an electrolyte-separator, an anode, and/or a cathode with the eutectic formulation of KOH and NaOH. The electrolyte in the electrolyte-separator can have a melting point from about 170° C. to about 300° C. making it suitable for use in a thermal battery that does not require a pyrotechnic device for certain high-temperature applications.

1. An electrolyte-separator comprising:
an electrolyte material comprising a eutectic formulation of KOH and NaOH; and a binder; wherein the electrolyte material is in a solid state at ambient temperatures; the electrolyte material has a melting point of about 180° C. to about 290° C.; and a ratio of KOH to NaOH in the eutectic formulation of KOH and NaOH is from about 40:60 wt % to about 65:35 wt %.
