The MOF-based device shows an areal capacitance that exceeds those of most carbon-based materials and capacity retention greater than 90% over 10,000 cycles, in line with commercial devices. One class of materials that far surpasses even the porosity of activated carbons is metal–organic frameworks (MOFs). —Sheberla et al.
