VERY HIGH POWER DENSITY BATTERIES FOR AIRBORNE APPLICATIONS

THE AIR FORCE NEEDS HIGH POWER DENSITY RESERVE BATTERIES FOR AIRBORNE APPLICATIONS WHICH MUST PROVIDE PULSES OF POWER AT RATES OF OVER 10,000 W/# DURING A LIFETIME OF 300 SECONDS. AN AVERAGE POWER DENSITY REQUIREMENT OF 50 WH/# MAKES THIS A CHALLENGING TASK. SMALL SILVER-ZINC BATTERIES HAVE BEEN REPORTED TO YIELD THIS LEVEL OF POWER IN SINGLE BURSTS, BUT AT ONLY HALF THE ENERGY DENSITY. THE ENCLOSED PROPOSAL DESCRIBES AN INNOVATIVE CONCEPT FOR EXTREMELY HIGH POWER DENSITY, FUNCTIONING ON PRINCIPLES NOT PREVIOUSLY USED IN ELECTROCHEMICAL POWER SYSTEMS. FEASIBILITY OF 100 WH/# HAS BEEN SHOWN, AND POWER DENSITY SIGNIFICANTLY HIGHER THAN THE REQUIRED 10,000 W/# IS ANTICIPATED FROM THIS NEW CONCEPT.
