摘要FeS nanosheets were synthesized and used as anodes to investigate their electrochemical properties and reaction mechanism during the lithiation and delithiation processes by using in-situ transmission electron microscopy. The FeS nanosheets converted to Fe nanoparticles of 2-3 nm embedded within Li2S matrix after the first lithiation. Then the Fe and Li2S transformed into Li1.13FeS2 instead of FeS during the first delithiation. The reversible phase conversion between Fe/Li2S and Li1.13FeS2 dominated the following cycles. The nanosheets structure was well held with small volume expansion during several lithiation and delithiation cycles. (C) 2016 Elsevier B.V. All rights reserved.
