In article number 2001756, Hyung Mo Jeong, Jeung Ku Kang, and co‐workers describe high‐tap density anode and cathode structures with stratified graphene pliable pockets allowing high gravimetric energy densities (up to 206.9 Wh kg −1 ). Indeed, assembling both electrodes into the full‐cell devices outperform the energy densities of supercapacitors by ≈16 fold along with long cycle stability. In addition, they enable the ultrafast chargeable power densities exceeding those of commercial batteries by more than 100 fold.
