METHOD OF STORING ELECTRICAL ENERGY

摘要

METHOD OF STORING ELECTRICAL ENERGY A method for the useful storage of electrical energy is described in which an electrochemical cell employing a halide electrolyte and an ungraphitized carbon positive electrode is charged at a voltage substantially below the conventional decomposition voltage required to produce free halogen from the selected electrolyte. An unidentified chemical complex is formed and stored at the positive electrode, and the positive electrode may thereafter be employed as an electrical energy source in a primary or secondary battery.
