Electrode Separator Doubles As A Battery Safety Sensor
A new design of an insulating material that separates the electrodes in lithium-ion batteries may help prevent a rare but potentially disastrous scenario that can cause these batteries to suddenly go up in flames. A small number of burning-battery incidents, including two last year involving Boeing 787 Dreamliner airplanes, have kept lithium-ion batteries in the safety spotlight.
