Energy storage devices, such as supercapacitors, need to work at temperatures greater than 100°C for applications in ultrahigh power electronics and electric vehicles. However, it has proved difficult to make such devices in the past. Now, a team of researchers from Korea and the US has succeeded in fabricating flexible supercapacitors that have high energy and power densities at 120°C. The new devices are as good as, if not better than, previously reported solid-state capacitors operating at much lower temperatures….
