Lithium-ion batteries are heat intolerant, according to a potential whistleblower familiar with their technology. "Too much heat on those things, they will go into a thermal runaway, they will explode." The informant, a former senior engineering technician of Securaplane Technologies, was fired in 2007 for repeated misconduct, but he says it was in retaliation for voicing concerns about the batteries. The NTSB acknowledges that the lithium-ion batteries in Boeing's (BA) Dreamliner experienced a thermal runaway, but insists there's no connection between the incident and the whistleblower's claims.
