The Consumer Product Safety Commission is urging anyone who owns a Samsung Galaxy Note 7 smartphone to stop using it immediately after at least 35 reports that the phone's lithium-ion battery could explode. The FAA says airline passengers should keep them turned off while on a plane. Samsung has recalled about 2.5 million of the expensive new phones and agreed to replace every one.
Class discussion: Does this warning make you wary of Samsung phones? Can you find other cases of exploding lithium-ion batteries? What causes the batteries explode? Does it make you uneasy about using devices with lithium-ion batteries? How many electrical devices do you use that are powered by lithium-ion batteries? Airlines have banned some devices and cargoes. But could they ever ban all lithium-ion batteries from planes?
