Dual-ion batteries (DIBs) have been attracting great attention for the storage of stationary energy due to their low cost, environmental friendliness, and high working voltage. However, most reports on DIBs involve low-mass-loading electrodes (<2.5 mg), while use mass-loading (>10 mg cm-2 ), which are critical practical application, is overlooked. Herein, an integrated free-standing functional carbon positive electrode (named MSCG) with a "point-line-plane" hierarchical architecture at level ultrahigh (>50 ) developed high-energy-density DIBs. The rationally designed microstructure advanced assembly method that adopted produce well-interconnected ion/electron transport channel in MSCG electrode, confers rapid kinetic properties maintaining good mechanical properties.
