Samsung Isn't the Only One with Lithium Ion Battery Problems. Just Ask NASA

On June 14, 2016, four researchers at the Jet Propulsion Laboratory were preparing to ship a waist-high, ape-like robot named RoboSimian off-site. They had built the bot to rescue people from dangerous situations that human rescuers can't hack. The scientists swapped one lithium-ion battery for a fresh one, then left for lunch to let the new power supply charge. Left alone in the lab, RoboSimian's battery did what such batteries famously do: went boom. Plumes of smoke vented from the robot's exposed torso, followed by a burst of flame.
