“…[33] The visible plastic deformation demonstrates that the 3D-Cu possesses a macroscopically ductile behavior, indicating its decent potential as an engineering material. [34] In contrast to other recently reported self-supported pure or carbon/copper-hybridized Sb anodes for SIBs, the Sb@3D-Cu electrode expresses commendable overall electrochemical capability, effectively striking a balance between specific capacity and stability even at comparatively high current densities (Figure S14, Supporting Information). When compared to the Sb@Cu electrode, the impressive performance of the Sb@3D-Cu electrode can be credited to the unique nanostructure of the 3D-Cu substrate.…”

Sodium‐ion batteries (SIBs) represent a viable substitute to lithium‐ion batteries due to their affordability and resource abundance. For SIBs, antimony (Sb) shows potential as anode material but is impeded by the high volumetric variations. Here the challenges of Sb sodium storage by introducing the nanostructured Cu substrate for enhanced Sb adhesion and morphology optimization is addressed, which is realized by fused deposition modeling (FDM) printing of Cu substrate, subsequent high‐temperature sintering, and electrodeposition of Sb. In SIBs, the Sb deposited on three dimensional (3D) printed Cu substrate performs improved cycling stability compared with that of Sb@Cu with commercial Cu foil substrate, which can be attributed to the nanostructure of the 3D‐Cu substrate. Such architecture of 3D‐Cu induces the generation of pine‐leaf‐like Sb clusters to promote stability and kinetics, and it aids the adhesion between the Sb cluster and 3D‐Cu substrate for preventing the Sb detachment and restructuring the Sb cluster to the robust porous ligament‐channel Sb framework. The morphology evolution, (de)sodiation mechanism, and gas evolution are explored by ex situ scanning electron microscope, operando X‐ray diffraction, and operando differential electrochemical mass spectrometry separately. The developed Sb@3D‐Cu anode offers a flexible pathway for constructing 3D‐printed self‐supported electrodes for SIBs.

“…11 When the inert metal substrate is a thin film, the liquid Ga-assisted alloying–dealloying strategy is also employed to design porous metal films with tunable porosity and thickness. 70 This low-temperature method allows accessibility to well-controlled nanoporous metals, offering scalability and low energy costs. 71 The resulting nanoporous metals are crucial in diverse applications, including catalysts, 72 actuators, 73 sensing/biosensing 74,75 and energy systems, 76 owing to their bi-continuous channel-ligament structure and high surface area.…”
