Abstract
The Army has a requirement for rechargeable lithium-air cells and batteries for Silent Watch needs. The cells are uniquely qualified for these needs because of their higher cell voltage and specific energy density compared with other battery systems. The lightweight lithium-air battery has the potential to meet the Army"s needs, provided certain material characteristics and design features can be improved for extended lithium anode rechargeability, electrolyte stability and decreased air cathode polarization. During Phase I Giner demonstrated a design approach for the cell based on its experience with high voltage electrolytes and cathode structures used in fuel cells. During Phase II, these advances will be optimized to achieve the desired 1000 Wh/kg and 200 full charge/discharge cycles at the C/20 rate. Designs will be prepared for lightweight prototype cells and multi-cell batteries with efficient air cathodes, low internal impedance and hermetic seals to protect the lithium anode during storage and operating lifetime. Cells and batteries will be fabricated at Giner and delivered to the Army for their testing and evaluation.
