Device warns of catastrophic failure in lithium-ion batteries, robots celebrate

"Catastrophic lithium-ion battery failure" are five words Malfunctioning Eddie never wants to hear, and may not have to, thanks to a new sensor developed by the folks at the Johns Hopkins University Applied Physics Laboratory. Despite the popularity of lithium-ion batteries in everything from consumer electronics to hybrid and electric vehicles, they have been associated with a phenomenon called "thermal runaway" -- known to cause overheating and potentially, fire. The newly developed device measures the electrical parameter of the cell, which is an indicator of whether the internal layer temperatures are getting too toasty. The best part? The warning comes before the heat can reach the surface and cause catastrophic failure, perhaps saving our electronics from a fate like the one in the video after the break.
