HIGH ENERGY/POWER DENSITY RAPID DISCHARGE BATTERIES - NEW APPROACH

NOVEL BATTERY CONFIGURATIONS WITH MICROELECTRODES ARE DESCRIBED. THESE BATTERIES SHOULD EXHIBIT VERY LOW INTERNAL CELL RESISTANCE, GREATLY REDUCED CONCENTRATION POLARIZATION EASE OF ACTIVATION IN THE RESERVE MODE AND EXTREMELY RAPID DISCHARGE. THEORETICAL CONSIDERATIONS PROVIDE THE BASIS FOR PRELIMINARY DESIGNS OF LI/SOC1(2) CELLS WITH MICROELECTRODES. AN EXPERIMENTAL PROGRAM IS DESCRIBED TO DEVELOP THE TECHNIQUES REQUIRED TO FABRICATE BENCH SCALE TEST CELLS, STUDY THEIR DISCHARGE CHARACTERISTICS IN THE MILLISECOND TIME FRAME AND MODEL THEIR BEHAVIOR. THE CONCEPT HAS WIDESPREAD GENERIC APPLICATIONS TO OTHER BATTERIES AND ELECTROCHEMICAL DEVICES.
