I've been reporting on electric vehicles for over a decade now. And the one question I'm still asked about, as well as still report on, is about thermal runaway.
For those who've never heard the term, it's when a single battery cell on an electric vehicle is heated to the point of combustion and, rather than it extinguishing itself as designed, gets so hot it sets the next cell on fire. And then the next. And the next. And so on and so forth.
