Applicability of MIL-101(Fe) as a cathode of lithium ion batteries

Abstract

MIL-101(Fe) was investigated as a cathode material of lithium ion batteries. A battery test reveals that MIL-101(Fe) shows a charge and discharge capacitance of 110 mA h g. It also showed reversible charge and discharge cycles and uptake of 0.62 Li/Fe after 100 cycles, which is the highest loading amount ever reported for the carboxylic MOFs. It also operates in the temperature range up to 350 °C and showed a good high thermal stability.

Heterogeneous Fenton-like catalysis of Fe-MOF derived magnetic carbon nanocomposites for degradation of 4-nitrophenol

“…in previous reported literatures. 35,36 Aer heat treatment at 400 C, the as-obtained Fe-C 400 exhibits that the main diffraction peaks appear in three areas between 8 to 10 , 15 to 20 and 28 to 35 , which is different with that of the bare Fe-MOF. It indicates that the phase of Fe-MOF was completely changed at 400 C because of loss of part of oxygen-containing groups.…”

Synthesis and Electric Properties of a Two‐Dimensional Metal‐Organic Framework Based on Phthalocyanine

“…Meanwhile, stable 3D nanoporous structures with redox activity have received much interest as electrode materials in lithium ion batteries (LIBs), since the porous structure facilitates the ion transportation and prevents the structural deterioration that arises from the insertion of Li ions . While there have been some reports of utilizing conductive 2D MOFs in chemical sensors and electric double layer capacitors, their utilization as LIB electrodes has remained scarce .…”

Metal-Organic Frameworks for Batteries

“…The early works are focused on a series of Fe-based MOFs with the Fe 3+ /Fe 2+ redox couple serving as electroactive sites for lithium storage. [19][20][21]89,90 The electrochemical capacities of these MOFs were not exceptional due to the limited numbers of inserted lithium ions per MOF formula, which were only $0.6 and $0.35 for MIL-53 (Fe) 19 and MIL-68 (Fe), 20 respectively. Theoretical calculations on MIL-53(Fe) revealed that, when the intercalation number was above the upper limit, further lithiation could destabilize the local environment of the metal ions, cause a dramatic loss of cohesive interaction, and finally lead to an irreversible structural destruction.…”
