In article number 1803695 , Hyung Mo Jeong, Jeung Ku Kang, and co‐workers describe high‐performance aqueous energy storage realized by porous Mn 3 O 4 positive electrodes and Fe 2 O 3 negative electrodes. Aqueous hybrid capacitors give high energy densities exceeding those of aqueous batteries and are stable over 30 000 cycles, along with ultrafast charging capability so that full cells in series can be charged within several seconds by a rapid USB charger.
