Wide-temperature range operation supercapacitors from nanostructured activate…

a b s t r a c t Electrochemical power sources that offer high energy and power densities and, can also withstand a harsh temperature range have become extremely desirable in applications ranging from civilian portable electronic devices to militaryweapons. In this report,we demonstrated a wide temperature withstanding supercapacitor which can be operated from 100 ◦C to −40 ◦C within a…
