So far the most promising material to surround a carbon-anode inside a pouch, as part of a lithium battery, is Lithium difluoro(oxalato)borate, CAS 409071-16-5. A white powder soluble in a range of non-polar solvents.



This inorganic compound where a two carbon dioxides have replaced two fluorines is more effective than lithium tetrafluoroborate LiBF4 or lithiumhexafluorophosphate LiPF6 and is non-toxic and stable over a much wider range of conditions than these alternatives.

I use lithium fluoride as a flux in ceramics, a white powder costing about $34 a pound. Combining fluoride with either lithium or boron is extremely exothermic, so not even the heat of a 2,400 F ceramic kiln can liberate free fluorine gas from this bond.

Lithium borate is the basis of glass with extremely-low thermal-expansion, used in glass or ceramic cookware.
