Title: Novel Electrolytes for -100?C Lithium Battery Applications
Agency: NASA
Contract: NNJ06JD72C
Award Amount: $70,000.00
 

Abstract:

NASA requires advanced high power primary lithium batteries for ultra low temperature applications. The key component that limits the performance at low temperature is the battery electrolyte. Proof-of-concept experiments have shown that Covalent's new non-aqueous electrolyte formulations greatly enhance low temperature primary battery performance while preserving its long shelf life. At temperatures as low as -100oC, our new electrolyte demonstrates superior transport properties due to minimal triple ion formation. Accelerated storage tests revealed no voltage delay indicative of a stable passive film formed on the lithium anode. When coupled with a high energy density cathode material such as carbon monofluoride (CFx), our new electrolyte formulations will enable primary lithium primary performance over a broad spectrum of ultra low temperature applications. Specifically, Li/CFx batteries incorporating the new Covalent electrolytes will deliver more than 30% of their room temperature capacity at temperatures as low as -100oC at practical discharge rates.
