This article leaves out a lot of history of the lithium-ion batteries -- there were tons of companies using them in the late 80s and early 90s.
I ported software for testing them under various temperatures for use in down-hole horizontal drilling equipment in the late 80s. When looking up my old company when writing this post, I ran across the following list of hundreds of companies getting permission to transport them (hazardous back then too!) in 1991 from the DOT, and a 1973 technical report from the US Army on appropriate lithium ion battery testing procedures, which seems earlier than much of the research discussed in this article:
