Abstract

Carbon monofluoride (CFx) has been extensively used as a reliablecathode material in lithium primary batteries because of its high energy densityand long shelf life. However, the implementation of Li/ CFx batteriesin high-power applications is limited by the low power capability resulting fromthe insulative nature of CFx material. In this work, we incorporatedmulti-walled carbon nanotubes into CFx electrodes and studied theimpact on the electrochemical performances when CNTs were used as a conductiveadditive material and current collector substrate. Our work demonstrated thepromising utilization of CNTs in CFx electrodes in improving thepractical capacity and power capability of Li/ CFx batteries.
