THIS STATEMENT OF WORK (SOW) IS THE RESULT OF A PROPOSAL SUBMITTED BY AMPRIUS, INC. FOR AWARD UNDER THE NASA HEADQUARTERS OFFICE OF CHIEF TECHNOLOGIST BROAD AGENCY ANNOUNCEMENT (BAA) ENTITLED UNIQUE&INNOVATIVE SPACE TECHNOLOGY. THE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION S SPACE TECHNOLOGY GAME CHANGING TECHNOLOGY (GCT) DIVISION FOCUSES ON DEVELOPING RADICALLY NEW APPROACHES TO THE AGENCY S FUTURE SPACE MISSIONS AND THE NATION S SIGNIFICANT AEROSPACE NEEDS. SUCCESSFUL PRODUCTS OF GCT WILL PROVIDE OR LEAD TO REVOLUTIONARY ADVANCES IN CAPABILITY. THE FOCUS OF THIS EFFORT IS TO DEVELOP THE CHEMISTRY THAT WILL ALLOW FOR THE MANUFACTURE OF ULTRA-HIGH CAPACITY BATTERY CELLS THAT WILL FUNCTION WITHIN THE EXTREMES THAT CHARACTERIZE A NASA MANNED SPACE MISSION. TWO OF THE MOST PRESSING REQUIREMENTS, WHEN COMBINED WITH PURE ENERGY REQUIREMENTS, ARE OPERATING TEMPERATURES AND THE ABILITY TO CYCLE 100 S OF TIMES WHILE STILL MAINTAINING THE ABILITY TO HOLD A CHARGE. THIS EFFORT WAS SELECTED FOR THE CONTRACTOR S DEMONSTRATED SUCCESS WITH SILICON NANO-WIRE (SNW) ANODE/NICKEL, COBALT, ALUMINUM (NCA) CATHODE CHEMISTRY THAT APPROACHES THE DESIRED ENERGY STORAGE ATTRIBUTES OF NASA S TECHNOLOGY ROADMAP CYCLE 2 . WHAT THIS WORK SEEKS TO ACCOMPLISH IS AN EXTENSION OF THIS TECHNOLOGY TO THE OTHER REQUIREMENTS THAT DEFINE NASA S SPACE MISSION AND WHICH TO DATE HAVE NOT BEEN SATISFIED, E.G. OPERATIONAL RANGES OF -200C TO 300C. UNDER THIS EFFORT, THE CONTRACTOR SHALL LEVERAGE THEIR PAST ADVANCES IN SNW TECHNOLOGY, WHICH HAS BEEN DEMONSTRATED TO PROVIDE HIGH ENERGY CAPACITIES AND GOOD CYCLING CHARACTERISTICS, WHILE FOCUSING THEIR PRESENT EFFORTS ON DEVELOPING A BATTERY CELL CAPABLE OF WITHSTANDING THE ENVIRONMENTAL EXTREMES THAT NASA REQUIRES, AND VIA TESTING, DEMONSTRATE A FINAL TECHNOLOGY READINESS LEVEL (TRL) 5 FOR THE COMPONENT TECHNOLOGIES. IN AGGREGATE, THIS EFFORT IS COMPRISED OF FOUR MAIN TASKS. TASK 1 REQUIRES THE CONTRACTOR TO EVALUATE BATTERY ELECTROLYTES FOR POSSIBLE USE WITH SNW ANODES UNDER THE ASSUMPTION THAT LOW TEMPERATURE OPERATION AND MULTIPLE CYCLES ARE REQUIRED. IN TASK 2, THE CONTRACTOR SHALL DEVELOP FULL CELL BATTERIES BASED UPON SNW ANODES, NCA CATHODES, AND AN ELECTROLYTE DETERMINED THROUGH COMPONENT TESTING CONDUCTED IN TASK 1. THESE CELLS SHALL BE DELIVERED TO BOTH THE NASA JET PROPULSION LABORATORY (JPL) AND NASA GLENN RESEARCH CENTER (GRC) FOR INDEPENDENT TESTING. UNDER TASK 3, THE CONTRACTOR SHALL DEVELOP A SECOND SET OF FULL CELL BATTERIES BASED ON A SNW ANODE, NICKEL, MANGANESE, COBALT (NMC) CATHODE, AND AN OPTIMIZED ELECTROLYTE. THESE CELLS SHALL ALSO BE DELIVERED TO BOTH THE JPL AND GRC FOR INDEPENDENT TESTING. FINALLY, IN TASK 4 THE CONTRACTOR SHALL PROVIDE A WHITE PAPER THAT OUTLINES POTENTIAL FUTURE RESEARCH ASSOCIATED WITH THE OPTIMIZATION OF SNW ANODES FOR LOW TEMPERATURE OPERATION BASED ON THE RESULTS OF THE RESEARCH CONDUCTED PURSUANT TO TASKS 1, 2 AND 3.
