Humic acid-based interlocked MOF: Enabling stable cycling performance at ultra-high current densities for lithium-ion batteries

Facile Preparation of Interlocked Fe2O3/MOF Composite for Boosted Rate and Cycle Performance of Lithium-Ion Batteries

“…As a kind of “star material” notable for its high porosity, metal–organic frameworks (MOFs) have been widely used as precursors for the fabrication of advanced electrode materials. − One outstanding merit of this approach lies in that the structure and compositions of the electrode materials can be rationally designed by choosing the appropriate MOF precursor. , In a typical synthesis procedure, the MOF precursor was initially in situ synthesized through the hydrothermal/solvothermal method and then thermally treated to deliver the target composite electrodes. ,,− Unfortunately, significant enhancement in electrochemical properties including cycle stability of electrodes was achieved at the expense of the organic–inorganic complex structure of the MOF precursor. ,− In consideration of the unique structure and outstanding properties of MOF, pristine MOF-based composite electrode materials are even more attractive as the synergistic effects from each component (including pristine MOF) can be boosted . Therefore, the rational design of the Fe 2 O 3 /pristine MOF composite electrode is still of profound significance.…”
