Herein, a series integrated gradient Cu-based are fabricated by electrochemical growth CuO nanowire arrays on foil (CuO@Cu), where structures can be readily controlled modulating dispersities arrays. It is found that constructed sparse and dense dispersion both disadvantageous nucleation metal, consequently fast dendrite growth. In contrast, uniform appropriate dispersity enables stable bottom associated with smooth lateral deposition, affording ideal bottom-up pattern. The optimized CuO@Cu-Li electrodes exhibit highly reversible including coulombic efficiency up ≈99% after 150 cycles long-term lifespan over 1200 h. When coupling LiFePO4 cathode, coin pouch full-cells deliver outstanding rate capability. This work provides new insight design toward high-performance anodes.
