Of these PF 5 is rather short lived. The toxicity of HF and the derivate hydrofluoric acid is well known 22–24 while there is no toxicity data available for POF 3, which is a reactive intermediate 25 that will either react with other organic materials or with water finally generating HF. Judging from its chlorine analogy POCl 3 /HCl 24, POF 3 may even be more toxic than HF.

When electrolytes are burned (vinyl carbonate and propylene carbonate are burned), other toxic gases (mainly carbon oxides) are formed. To prevent the battery from leaking or burning, lithium-ion batteries must be handled with extreme care. If an electrolyte leaks from the lithium-ion battery, the liquid may contain hydrofluoric acid.
