摘要

Recently, NiMoO4 has attracted much interest because of its high theoretical capacity and redox activity as lithium-ion batteries (LIBs). However, its applications are limited by its poor cycling stability and rate performance. In this paper, NiMoO4 nanofibers (NiMoO4-NFs) were fabricated via scalable electro-spinning technique. The prepared NiMoO4-NFs were directly used as electrode materials without any current collector. Electrochemical tests demonstrated that the NiMoO4-NFs exhibited desired electrochemical performance including high reversible capacity (892.7 mA h g(-1)), superior long-term cycle stability and rate capacity (511 mA h g(-1) at 1 A g(-1) after 500 cycles). The electrochemical reaction mechanism was explored by using ex situ transmission electron microscopy. A two-phase reaction process was confirmed in the electrochemical reaction. The desired electrochemical properties made NiMoO4-NFs appropriate for the next generation of LIBs. (c) 2020 Elsevier B.V. All rights reserved.
