Abstract
An electrolyte system suitable for a molten salt electrolyte battery is described where the electrolyte system is a molten nitrate compound, an organic compound containing dissolved lithium salts, or a 1-ethyl-3-methlyimidazolium salt with a melting temperature between approximately room temperature and approximately 250° C. With a compatible anode and cathode, the electrolyte system is utilized in a battery as a power source suitable for oil/gas borehole applications and in heat sensors.
Claims9
An electrolyte system suitable for a molten salt electrolyte battery, the electrolyte system comprising a material with a melting temperature between approximately room temperature and approximately 250° C., said material selected from at least one molten nitrate compound having a melting point temperature of less than approximately 250° C., said molten nitrate compound consisting essentially of a mixture of lithium nitrate, potassium nitrate, and cesium nitrate, at least one organic compound containing dissolved lithium salts, and at least one 1-ethyl-3-methylimidazolium salt.
