Porous copper (Cu) current collectors show promise in stabilizing Li metal anodes (LMAs). However, insufficient lithiophilicity of pure Cu and limited porosity three-dimensional (3D) porous structures led to an inefficient Li–Cu composite preparation poor electrochemical performance anodes. Herein, we propose a Cu-CuZn (DG-CCZ) host for tackle these issues. This architecture features pore size distribution lithiophilic-lithiophobic characteristics designed gradient from the inside outside anode structure. dual-gradient exhibits exceptional capillary wettability molten provides high up 66.05%. design promotes preferential deposition interior structure during battery operation, effectively inhibiting dendrite formation. Consequently, all cell systems achieve significantly improved cycling stability, including half-cells, Li–Li symmetric cells, Li-LFP full cells. When paired synergistically with double-coated LiFePO4 cathode, pouch configured multiple electrodes demonstrates impressive discharge capacity 159.3 mAh g–1 at 1C. We believe this study can inspire future 3D enhanced utilization efficiency facilitate development high-energy batteries.

Abstract Unleashing the potential of lithium‐metal anodes in practical applications is hindered by inherent stress‐related challenges arising from their limitless volume expansion, leading to mechanical failures such as electrode cracking, solid electrolyte interphase damage, and dendritic growth. Despite various protective strategies “combat” stress anodes, they fail address intrinsic issue fundamentally. Here, a unique strategy proposed that leverages generated during battery cycling via piezoelectric effect, transforming adaptive built‐in electric field accelerate lithium‐ion migration, homogenize lithium deposition, alleviate concentration. The mechanism effect modulating electro‐chemomechanical evolution further validated decoupled through finite element method simulations. Inspired this strategy, high sensitivity, fast responsive, strength adaptability polymer used demonstrate feasibility corresponding protected anode shows stability over 6000 h under current density 10 mA cm −2 extending life variety coin pouch cell systems. This work effectively tackles issues decoupling also contributes developing more stable for future research.

Discontinuous and uneven Li+ flux leads to inhomogeneous reactions, accelerating lithium (Li) dendrite growth reducing the utilization of active materials, which severely impacts performance metal batteries (LMBs). To address this challenge, we propose an effective homogeneous reaction design facilitated by all-aligned nanofibrous architecture, establishes continuous, uniform, rapid pathways throughout battery. This enhances diffusion dynamics ensures a uniform distribution current density, hence promoting Li nucleation at anode efficient insertion/extraction cathode. Moreover, architecture exhibits superior mechanical strength flexibility, maintaining structural stability during long-term cycling suppressing growth, thereby minimizing risk short circuits. As result, LMBs incorporating exhibit exceptional electrochemical performance. work provides valuable insights into reactions for high-performance LMBs.
