Advanced Li/CFx Primary Batteries with Non-Flammable Electrolytes, Phase I

Completed Technology Project

Project Introduction

Advanced Li/CFx Primary Batteries with Non-Flammable Electrolytes, Phase I
NASA seeks to develop high specific energy primary batteries that are safe and capable of performing under a wide temperature range, for manned space missions. To meet this goal, CFX Battery Inc. proposes to develop, characterize, and establish technological feasibility of a new Li/SF-CFx based high capacity lithium primary battery that offers higher rate capability and enhanced safety than conventional Li/CFx primary systems. In Phase I of the project, CFX Battery will develop the sub-fluorinated CFx cathode materials that offer high capacity (>700 mAh/g) and rate capability. In addition, novel non-flammable electrolytes that are highly conductive and electrochemically stable at a wide temperature range will be developed to increase the safety of the Li/SF-CFx system. The technological feasibility of the sub-fluorinated CFx cathode and non-flammable electrolyte combination will be demonstrated using small coin and pouch cells. Phase II of the project will implement the developed technology in large cell formats and perform any refinement and optimization that will be needed to bring the technology to a commercially usable stage.
