Combing graphene with a metal-organic framework can produce a highly-porous and conductive electrode for supercapacitors, according to the Technical University Munich (TUM), which has built a device to prove it, that can challenge some battery technologies for specific energy capacity. “The new energy storage device does not only attain an energy density of up to 73Wh/kg, ...
