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 ...
