787 battery blew up in ’06 lab test, burned down building
The Arizona lab fire showed the challenges facing Boeing’s strategy to safely manage that energy, prevent such a blowout and contain any less serious battery problems.

In 2006, a devastating lab fire in Arizona showed just how volatile Boeing’s 787 Dreamliner lithium-ion battery can be if its energy is not adequately contained.
A single battery connected to prototype equipment exploded, and despite a massive fire-department response the whole building burned down.
On the finished Dreamliner, however, Boeing is confident its engineers can safely harness and contain that energy.
The 787’s battery-fire protection regime aims both to make a catastrophic blowout impossible through multiple independent controls and also to compartmentalize any less serious battery meltdown, venting smoke outside until the high-temperature reaction burns itself out.
