Is it true that burning lithium-ion batteries release toxic gases, including hydrogen fluoride?
Yes. A peer-reviewed study measuring emissions from seven commercial lithium-ion battery types reports that burning cells generate large amounts of hydrogen fluoride, and a Swedish fire-test report likewise identifies hydrogen fluoride as the toxic gas distinguishing electric-vehicle battery fires. Other fire tests confirm toxic gas release but do not name hydrogen fluoride specifically.
