ABSTRACT:
Homotetra-alkyl substituted quaternary ammonium salts, or mixtures thereof which crystallize at 30.degree. C. or lower are included as an additive to the electrolyte of halogen cells. To maintain the salts as liquids, means for heating the additives to temperatures greater than 30.degree. C. are included in the cell. The additives form complexes with elemental chlorine, bromine, iodine, or mixtures thereof in the electrolyte which complexes comprise predominantly electrolyte insoluble liquids at temperatures in excess of 30.degree. C. The additives are characterized by rapid halogenation and dehalogenation while liquid; and thus, if maintained at temperatures in excess of 30.degree. C., are well suited for halogen storage in battery or fuel cell applications.
