An electrochemical device is proposed that uses a novel electrolyte system technology, based on the use of conventional electrodes with high specific capacity selected to provide operating cell potentials within a range of approximately between 1.2 and 2.4 volts along with the use of an unconventional electrolyte solution. Specifically, his novel electrolyte system is based on the use of an aqueous electrolyte solution that has a window of voltage stability above the range of conventional aqueous electrolytes. Any of a variety of acid, neutral or basic aqueous solutions or gels with or without any of a variety of co-solvents, inorganic or organic salts or ionic liquids may be employed provided the conductivity and stability of the electrolytes are compatible with the selected electrochemical couples so as to provide high cell capacity, high rate capability and long term stability.
