On page 7754, H. Wu, S. X. Dou, and co‐workers describe engineering of transition‐metal‐oxide‐based hierarchically ordered 3D porous electrodes. Assembling ultralong 1D core‐sheath MnO@N‐doped graphene scrolls with 2D N‐doped graphene ribbons results in porous MnO nanowires that are mechanically isolated by their graphene scroll confinement, but electronically wellconnected by continuous graphene ribbon conductive networks, thus enabling a stable solid‐electrolyte interface and superior lithium storage properties.
