Producing fluorinated carbon useful as a battery electrode material comprises reacting a carbon material with fluorine and hydrogen fluoride in the presence of a fluoride, and fluorinating the product with fluorine

摘要

Producing fluorinated carbon comprises reacting a vacuum-degassed carbon material with a gaseous mixture of fluorine and hydrogen fluoride in the presence of a fluoride at 15-80[deg]C, and fluorinating the product with fluorine at 400-600[deg]C. Independent claims are also included for: (1) fluorinated carbon material (I) that consists of a hybrid phase comprising covalent and semi-covalent carbon-fluorine bonds and has a defined 13C NMR spectrum; (2) electrochemical generator comprising two electrodes in contact with an electrolyte, the positive electrode comprising (I).
