Nanoengineering of Ultrathin Carbon-Coated T-Nb2O5 Nanosheets for High-Performance Lithium Storage
Published on 2025-03-07 by Hualin Xiong, Changlong Du, Hongan Zhao, Lei Yu, Yongzhu Yan, Jinchuan Zhao, Gengping Wan, Liyong Wang, Guizhen Wang @MDPI
Abstract: Niobium pentoxide (Nb2O5) is a promising anode candidate for lithium-ion batteries due to its high theoretical capacity, excellent rate capability, and safe working potential. However, its inherent low conductivity limits its practical application in fast-charging scenarios. In this work, we develop an ultrathin carbon-coated two-dimensional T-Nb2O5 nanosheet composite (T-Nb2O5@UTC) through a facile solvothermal reaction and subsequent CVD acetylene decomposition. This unique design integrates a[...]
