| Summary: | In order to keep up with the energy demands of this technologically evolving world, much research have gone into finding ways to improve electrochemical performance for energy storage applications such as lithium ion batteries (LIB). The synthesis of two-dimensional (2D) nanosheets which are very thin is a feasible way to improve electrochemical performance due to their larger surface area compared to their bulk material and also fast diffusion of electrons.
In this study, very thin layers of FePS3 nanosheets are obtained by an exfoliation method from its bulk crystals. The sheets are then used as an anode material for LIBs. During the testing, FePS3 exhibited great electrochemical properties with respect to its cycling performance and rate capabilities showing better results compared to its bulk counterpart. A stable discharge current of 976.4 mAhg-1 is displayed after the 50th cycle at a rate of 0.1Ag-1. |
