Constructing an architectural host is demonstrated to be an effective strategy for long‐life lithium metal anodes (LMAs). Herein, an integrated 3D host for stable and ultrahigh‐rate LMAs is developed by a binary highly conductive network of 2D reduced graphene oxide (rGO) and 1D carbon nanofibers (CNF) anchored with 0D ultrasmall MgZnO nanoparticles (MgZnO/CNF‐rGO). A facile net‐fishing strategy is...
The viable Li metal anodes (LMAs) are still hampered by the safety concerns resulting from fast Li dendrite growth and huge volume expansion during cycling. Herein, carbon nanofiber matrix anchored with MgZnO nanoparticles (MgZnO/CNF) is developed as a flexible triple‐gradient host for long cycling LMAs. The superlithiophilic MgZnO nanoparticles significantly increase the wettability of CNF for fast...
In article number 2001992, Ying Yang and co‐workers design a triple‐gradient host for long cycling lithium metal anodes at ultrahigh current density. In the graphic, the wizard on a magic broom and the flying wild geese guided by color winds indicate the fast movement of rectified Li‐ion flux repeatedly plated/stripped on the host represented by the castle on the clouds.
A non-woven network of porous nitrogen-doping carbon nanofibers (PNCNFs) is prepared by electrospinning of polyacrylonitrile (PAN)/polyvinylpyrrolidone (PVP), followed by stabilization and carbonization. The specific surface areas, porosity and nitrogen content of PNCNFs can be easily controlled by adjusting the content ratio of PVP to PAN. The non-woven PNCNFs based network provides abundant interface...
