Fluorinated organic chemicals: Prospects in New Electrochemical Energy Technologies

Résumé

This contribution has been partly adapted from a special lecture intended to commemorate the Nobel prize, awarded one century ago, to Henri Moissan. It, is focused on fluorinated and perfluorinated molecules and macromolecules used in electrochemical energy sources, i.e. storage and conversion of energy. The latter, which figure indisputably among New Energy Technologies, include lithium batteries and fuel cells based on polymeric membranes both of which have tremendous development potential in terms of performances, safety and cost reductions. The advantages inherent in fluorine, in particular its electron-withdrawing effect and the oxidation stability that it provides to the carbon–fluorine bond, make it an asset in the search for new organic molecular and macromolecular anions with extensive delocalization of the negative charge, usable both in lithium batteries and fuel cells. As for fluorinated and perfluorinated macromolecule backbones, they are currently the reference material in fuel cell ionomeric membranes but some of them are also good candidates for use in lithium-ion batteries. This paper, far from being exhaustive, also emphasizes the economic aspects that influence material selection and also govern the future of basic research.
