Published: Feb. 9, 2022

Abstract Although zinc metal anodes have some intrinsic advantages for aqueous ion batteries, the notorious dendrites hamper its practical applications. Herein, a charge‐enriched strategy through MXene‐based polypyrrole (MXene‐mPPy) layers is explored toward dendrite‐free Zn anode. The MXene‐mPPy composed of mesoporous PPy on both sides Ti 3 C 2 T x ‐MXene exhibit an exceptional charge enrichment ability (149 F g −1 , 5 mV s ), which beneficial not onlying terms accumulating levels, but also to homogenize dispersions electric field and flux as used artificial interface Thus, anode with ultralong cycling lifespan up 2500 h superior rate capability achieved, further applied batteries long‐term span over 3000 cycles at 10 A .

Embedding Metal–Organic Frameworks for the Design of Flexible Hybrid Supercapacitors by Electrospinning: Synthesis of Highly Graphitized Carbon Nanofibers Containing Metal Oxide Nanoparticles

Small Structures, Journal Year: 2022, Volume and Issue: 3(9)

Published: July 8, 2022

Electrospun carbonaceous fibers have emerged as promising electrode materials for application in energy storage devices. However, their relatively poor electrical conductivity (due to amorphous carbon structures) and low capacitive performance lead prospects further application. Herein, a universal synthesis of highly graphitized nanofibers, containing various metal oxide nanoparticles (e.g., Fe 2 O 3 , NiO), by the pyrolysis metal–organic framework (MOF)‐embedded electrospun is reported. The resulting nanofibers exhibit large mesopore volumes, contain quantities Faradic nanoparticles, are graphitized. also excellent mechanical flexibility, provide fast ion transfer characteristics, pseudocapacitance combined with conductivity, leading specific capacitances. Consequently, asymmetric flexible hybrid supercapacitors assembled from ‐embedded (FOCNF) NiO‐embedded (NOCNF) high density 43.1 Wh kg −1 at power 412.5 W possess flexibility (capacitance retention 94.4% 180° bending 96.2% 30° twisting) superior cycling stability. This strategy provides new MOF‐based approach design multifunctional might
