  • Patent number: 9705133
    Abstract: The invention relates to the use of subfluorinated carbon nano-objects as an electrode material of primary lithium batteries, the electrode obtained by that use and a lithium battery comprising such an electrode. The subfluorinated carbon nano-objects used in the invention have a central part made of nonfluorinated carbon and a peripheral part made of fluorinated carbon of formula CFX where x represents the F/C atomic ratio, which is such that 0.25<x<1.1 and whereof the spectrum 19F MAS RMN has a single peak between ?150 and ?190 ppm/CFCl3 (outside of rotation bands). The invention applies to the field of storing and retrieving energy, in particular.
