  • Sodium hydroxide compositions for use in battery systems
    Patent number: 6013192
    Abstract: The present invention relates to a dry composition of materials to be used n a battery system. The dry composition comprises a mixture consisting of sodium hydroxide and sodium oxide. In a first reservoir in the battery system, the mixture is present in an amount sufficient to form with water a heated sodium hydroxide electrolyte solution having a 15% by weight concentration of sodium hydroxide. In a second reservoir in the battery system, the mixture is present in an amount sufficient to form with water a heated sodium hydroxide electrolyte solution having to up to about 75% by weight concentration of sodium hydroxide. The present invention also relates to a battery system and a method for generating electrical power which utilize the aforementioned dry composition of materials.
