Electric vehicles (EVs) and the use of Li-ion batteries have created a new demand for hydrofluoric acid (HF), and subsequently fluorspar as a source of fluorine. HF is an essential feedstock for lithium hexafluorophosphate (LiPF6) and lithium bis(fluorosulfonyl)imide (LiFSl) electrolytes and polyvinylidene fluoride (PVDF) used as binders, all important components of Li-ion batteries. In addition, HF is used in natural flake graphite processing to produce a spherical graphite material, essential for manufacturing the current anode of lithium-ion batteries. Both applications have created a compounded new demand that has been steadily growing over the last five years and is set to grow more rapidly in future.
