Porous Carbon Nanorods Induced by Electrostatically Assembling Carbon Quantum Dots Within the Confined Hollow Space of Halloysite for Lithium‐Ion Battery Anodes

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Halloysite nanotubes (HNTs) have hollow tubular structures and oppositely charged inner outer surfaces, providing unique platforms for materials synthesis. Herein, porous carbon nanorods (CNRs) are synthesized using a vacuum liquid phase impregnation coupled with carbonization strategy, where quantum dots serve as building blocks HNTs act nanoreactors. The CNRs feature rod‐like framework high graphitization abundant oxygen‐containing functional groups, possess hierarchical structure large specific surface area (1187.9 m 2 ·g −1 ) pore volume (1.606 cm 3 ). prepared applied anode lithium‐ion batteries exhibits superior rate capability reversible capacities of 167 mAh·g at 5000 mA·g present outstanding cycle stability 593 after 1000 cycles . Density theory calculations indicate that the groups enhance Li atoms adsorption on graphene. Among these, carboxyl group provides greatest enhancement, maximum energy reaching −2.02 eV. Particularly, coupling an LiNi 1/3 Co Mn O cathode in full cell further demonstrates electrochemical performance, underscoring practical potential these CNRs. This work opens new opportunities fabrication 1D nanostructures enhanced durability storage applications.
