Abstract

The use of glycerine, which has a high-boiling point, as an electrolytic solvent for battery related applications, uniquely permits the use in high-operating temperatures, while maintaining the stability of the glycerine based electrolyte. Most prior art storage cell batteries utilize a water base electrolyte, which inherently limits the operating temperature ranges of the battery. In addition, the water based electrolytes have a relatively high-evaporation rate, which affect the stability of such a water base electrolytic battery.

Utilization of Glycerine as a Nonaqueous Electrolyte

The use of glycerine, which has a high-boiling point, as an electrolytic solvent for battery related applications, uniquely permits the use in high-operating temperatures, while maintaining the stability of the glycerine based electrolyte. Most prior art storage cell batteries utilize a water base electrolyte, which inherently limits the operating temperature ranges of the battery. In addition, the water based electrolytes have a relatively high-evaporation rate, which affect the stability of such a water base electrolytic battery.

It is found that the glycerine electrolyte generates voltages at room temperatures as well as at elevated temperatures as high as 300 - 350 degrees F with good stability and no substantial decomposition. In addition, the very low- evaporation rate of the glycerine improves the long-term stability of the electrolyte.

One example of an electrolyte using a glycerine base consists of 5% by weight of disodium ethylenediaminetetraacetate dissolved in 95% by weight of glycerine.
