In article number 2001851, Jeung Ku Kang and co‐workers describe hybrid capacitors assembled by a metal‐organic frameworks‐derived anode, and a polyaniline chain networked cathode with mesoporous channels, conductive networks, and high capacity units. These hybrid capacitors achieve high energy densities (242 Wh kg −1 ) and ultrahigh power densities (28,750 W kg −1 ) allowing ultrafast charge within seconds by a photovoltaic charger, and long‐life stability over 100 000 cycles.
