Microfluidic‐Assisted 3D Printing Zinc Powder Anode with 2D Conductive MOF/MXene Heterostructures for High‐Stable Zinc−Organic Battery

Advanced Materials, Год журнала: 2023, Номер 36(6)

Опубликована: Ноя. 9, 2023

Abstract Zinc powder (Zn‐P) anodes have significant advantages in terms of universality and machinability compared with Zn foil anodes. However, their rough surface, which has a high surface area, intensifies the uncontrollable growth dendrites parasitic side reactions. In this study, an anti‐corrosive Zn‐P‐based anode functional layer formed from MXene Cu‐THBQ (MXene/Cu‐THBQ) heterostructure is successfully fabricated via microfluidic‐assisted 3D printing. The unusual strong adsorption ions using MXene/Cu‐THBQ can effectively homogenize ion flux inhibit hydrogen evolution reaction (HER) during repeated process plating/stripping, thus achieving stable cycling. Consequently, symmetric cell based on Zn‐P exhibits highly reversible cycling 1800 h at 2 mA cm −2 /1 mAh . Furthermore, Zn‐organic full battery matched 4‐hydroxy‐2,2,6,6‐tetramethylpiperidine‐1‐oxyl organic cathode riveted graphene delivers capacity maintains long cycle life.

Metal–Organic Frameworks Meet MXene: New Opportunities for Electrochemical Application

Energy Material Advances, Год журнала: 2023, Номер 4

Опубликована: Янв. 1, 2023

Over the past few decades, metal–organic frameworks (MOFs) have been recognized as most attractive energy-involved materials due to their unique features, including ultrahigh specific surface area, superior porous structure, and excellent customizability. Nevertheless, pristine MOFs suffer from low electronic conductivity chemical instability, which severely hindered large-scale applications. Recently, MXene with abundant terminations high metallic suggested a valid substrate improve stability of MOFs. Importantly, MXene/MOF composites enhanced conductivity, rich chemistry, hierarchical structure facilitate rapid electron/ion transfer deliver better electrochemical properties than that original through synergistic effects. Moreover, can be designed into various derivatives desired architecture performance. Therefore, elaborate synthesis hybrids for devices are great interest. Herein, we provided state-of-the-art review on progress in terms strategies Furthermore, put forward current challenges feasible research directions future development.
