| Abstract |
In this research, Fe-MOF (MIL-53(Fe)) was synthesized by solvothermal and applied
as an anode of lithium-ion batteries (LIBs). Carbonaceous material from pyrolyzed bacterial
cellulose (pBC) was incorporated in the solvothermal synthesis of MIL-53(Fe) to improve its
morphology and electrochemical properties. The MIL-53(Fe) with pBC addition (MIL-53(Fe)@pBC) exhibited reduced particle size and size distribution, larger surface area and pore
volume, and modified crystal shape and interior structure. The incorporation also altered the
functional group of the dicarboxylic ligand and formed a thin carbon layer coating which
enhanced electrical conductivity significantly. The refined microstructure of the MIL-53(Fe)@pBC compared to the pure MIL-53(Fe) was proved to enhance the electrochemical
activities of the LIB cells. The specific capacity, rate capability, and cyclic performance were
boosted with pBC addition due to the increased ion diffusion kinetics in the
lithiation/delithiation process. Interestingly, the MIL-53(Fe)@pBC anode showed a peculiar
increase in the reversible capacity with LIB cycles after the initial capacity fading. The analysis
after the 100th cycle suggested that the lithiation/delithiation process was mediated by phase
transformation through the Li+ storage mechanism. This work has shown that the MIL-53(Fe)@pBC is an excellent candidate for anode materials in LIBs with high efficiency at long
life cycles. |
