The revolutionary electrical design of the Boeing 787 Dreamliner has led to a major problem: the lithium ion batteries used are too large and are charged too fast, allowing the batteries to approach their red zone temperature of 140°C (284°F) causing fire and/or explosion. Charged Li-ion batteries contain cobalt dioxide, a strong oxidizer like nitrate in gunpowder, and flammable lithium metal. The only thing missing is enough temperature to get the show on the road. Large batteries do not dissipate heat well, and the 65 amp-hour Boeing batteries are guilty as charged (pun intended). And I bet you're staring uneasily at your cell phone about now.
