THERMODYNAMIC JUSTIFICATION OF THE FEASIBILITY OF REGENERATION OF FLUORINE AND LITHIUM FROM LITHIUM- AND FLUORINE-CONTAINING SALTS. LITHIUM HEXAFLUOROPHOSPHATE

Using thermochemical calculations and calculations of thermodynamic equilibrium compositions of substances
in the Li–P–F–O–H and Li–P–F–O–H–C element groups, the feasibility of regenerating fluorine and lithium from
lithium hexafluorophosphate (a component of the electrolyte of lithium-ion batteries) during its interaction with
hydrogen or with methane and oxygen in combustion mode to close the production–operation–utilization cycle of
lithium-ion batteries for fluorine and lithium has been demonstrated
