3D porous Zn-metal anodes have aroused widespread interest for Zn-ion batteries (ZIBs). Nevertheless, the notorious "top-growth" dendrites caused by intrinsic top-concentrated ions and randomly distributed electrons may ultimately trigger a cell failure. Herein, an electron/ion-flux dual-gradient Zn anode is reported dendrite-free ZIBs adopting printing technology. The 3D-printed with layer-by-layer bottom-up attenuating Ag nanoparticles (3DP-BU@Zn) establishes electron/ion fluxes, i.e., internal gradient electron flux created bottom-rich conductive nanoparticles, ion resulting from zincophilic which pump toward bottom. Meanwhile, 3D-printing-enabled hierarchical structure continuously conducting network endow unimpeded transfer diffusion among electrode, dominating bottom-preferential deposition behavior. As result, 3DP-BU@Zn symmetrical affords highly reversible plating/stripping extremely small voltage hysteresis of 17.7 mV superior lifespan over 630 h at 1 mA cm-2 mAh . 3DP-BU@Zn//VO2 full exhibits remarkable cyclic stability 500 cycles.
