DEVELOPMENT OF LIGHTWEIGHT QUIET POWER SOURCE

A NOVEL CONCEPT FOR A LIGHTWEIGHT QUIET POWER SOURCE FOR A COOLING BACKPACK IS PRESENTED. A DYNAMIC HIGH ENERGY FLOW BATTERY OPERATING NEAR ROOM TEMPERATURE WITH AN ELECTRICAL OUTPUT OF 300-400 WATTS IS PROPOSED THAT CAN BE READILY SHUT-DOWN AND RESTARTED. THE ATTRACTIVENESS OF THE NEW SYSTEM IS BASED ON: A) VERY HIGH ENERGY DENSITY; B) POTENTIAL BROAD RANGE OF POWER DENSITY CAPABILITIES, C) SAFETY OF THE SYSTEM AND REACTANTS (AQUEOUS ELECTROLYTE); D) LOW COST OF REACTANTS PER UNIT ENERGY GENERATED. THE PHASE I PROGRAM IS DESIGNED TO DEVELOP THE PRELIMINARY DESIGN CONCEPT AND EVALUATE THE DYNAMIC CATHODE WITH TWO VARIANTS OF THE ELECTROLYTE AND TO OBTAIN INITIAL CELL PERFORMANCE DAATA FROM A SMALL LAB CELL. A PRELIMINARY DESIGN APPROACH FOR A 360 WATT POWER SOURCE WILL BE DEFINED FOR DEVELOPMENT IN PHASE II.
