  • Patent number: 4663252
    Abstract: The electrochemical cell has an alkaline metal or alkaline earth metal negative active material, such as lithium, and an electrolyte comprising a solute and at least one solvent selected from the liquid oxyhalides group, which also serves as the positive active material. In accordance with the invention the electrolyte further contains an organic compound which has the effect of significantly reducing voltage delay.

  • Patent number: 4547441
    Abstract: In an electrochemical cell the negative active material is an alkali or alkaline earth metal, such as lithium, and the electrolyte comprises a solute and at least one solvent selected from the liquid oxyhalides and which serves also as the positive active material. The electrolyte further comprises a mineral substance the effect of which is to significantly reduce the voltage rise delay of the cell.
