摘要

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.
