'Thermal switches' dynamically moderate heat of electronic devices

Modern devices that use lithium ion batteries, like smartphones and electric cars, seem pretty robust. But try to use one in extreme heat or cold, and you'll see how susceptible they are to malfunctions and low performance due to temperature. Purdue University engineers have developed a solution: a "thermal switch" made up of compressible graphene foam, that dynamically adjusts to temperatures both inside and outside the device to maintain consistent thermal management.
