Dec 23, 2022 · Herein, we propose an interface material consisting of three-dimensional (3D) nanostructured Zn-Cu alloy (i.e., Zn 5 Cu), which can successfully solve the inherent interface instability...

Jul 14, 2023 · In this contribution, we demonstrate a novel 3D composite Zn anodes with ultrahigh Zn plating/stripping rates and capacities as well as superior long-term cycling life, which is constructed...

Apr 11, 2024 · In the past three years, the 3D printing technology based on novel biodegradable Zn alloys has rapidly advanced, aiming to reduce material consumption while maintaining sufficient mechanical ...

May 24, 2018 · Here we use an electrochemical deposition method to in situ form a three-dimensional (3D) zinc anode on carbon fibers (CFs). This 3D Zn@CFs framework has lower charge transfer resistance with larger electroactive areas.

Herein, a 3D Zn anode exposing Zn(002) crystal planes (3D-Zn(002) anode) is first constructed by an electrostripping method in KNO 3 solution. Experiments and theoretical calculations indicate that the priority adsorption of KNO 3 on Zn(100) and Zn(101) planes decreases the dissolution energy of Zn atoms, thereby exposing more Zn(002) planes.

Feb 7, 2024 · Herein, a lightweight 3D-Cu architecture with customizable geometries is developed to enable reversible Zn-metal cycling. The 3D-Cu is prepared by 3D-printing a crosslink-able polymer scaffold followed by Cu-metallization.

Jan 15, 2025 · Herein, a fast ion transport network enhanced 3D Zn anode prepared by 3D printing is reported to regulate the electrochemistry of Zn. 3D structure design help to explore the impact of geometric constraints on ion diffusion-nucleation behaviors, validating boundary conditions of nucleation theories, so as to achieve a dense and uniform ...

Oct 1, 2022 · In this work, 3D In@Zn@In efficiently combines the advantages of In@Zn@In trilayer structure and 3D porous framework, and shows highly stable Zn storage for over 400 h in symmetry cell and 2000 cycles in full cell coupled with Mn 2 O 3 cathode.

Nov 14, 2024 · The stable 3D Zn-MnO2 battery with a high capacity retention (84.2% over 500 cycles) is also demonstrated. Zinc powder-based anodes encounter significant challenges, including severe side-reactions and non-uniform Zn plating-stripping processes.

Jan 21, 2025 · The Zn-3D and ZnS@Zn-3D symmetric cells exhibit a stable 3D diffusion process after 28 s and 60 s 2D planar diffusion nucleation, respectively. The results show that the ultrasonic etching treatment helps to inhibit the 2D diffusion of Zn 2+ and promote the uniform nucleation of Zn 2+ .
