Metal-organic frameworks and their derivatives as anode material in lithium-ion batteries: Recent advances towards novel configurations

Abstract

Lithium-ion batteries (LIBs) have drawn extensive research interests due to their noticeably enhanced gravimetric energy density relative to other chemical batteries. The potential utility of metal-organic frameworks (MOFs) and their derivatives has recently been recognized as highly effective anode components for LIBs because they can be tuned to select specific metal sites and/or to adjust pore sizes. In this work, their electrochemical performance as anodic materials is carefully evaluated with respect to lithium-ions storage capacity, energy/power, stability, and flexibility. Furthermore, through the coordination of the organic linker and metal center, MOFs can benefit from enhanced catalytic activities in the design of advanced LIBs. For future research for next-generation LIBs, scientific focus should be placed on the development of diverse features of MOF-based composites such as core-shell MOFs, mono/bi-metal doped MOFs, dual organic linker-based MOFs, MOFs@MOFs core shell structure, and dual organic ligands-based MOF. As such, MOF-based LIB electrode materials are expected to expand their utility with the improvement in topology and functionality in association with the dimensionality, pore size, and surface area.
