Electrochemical discharge mechanism of fluorinated graphite used as electrode in primary lithium batteries Original Research Article

In order to better understand the low faradic yield of low temperature fluorinated graphite used as electrode in primary lithium batteries, a study of the discharge mechanism has been performed. The evolution of some physico-chemical parameters such as C–F bond nature and structure of the fluorocarbon matrix has been determined by X-ray diffraction, solid state 19F NMR and EPR as a function of the depth of discharge. The influence of residual catalytic species on electrochemical properties will be also discussed.
