Metal‐Organic‐Framework‐Based Cathodes for Enhancing the Electrochemical Performances of Batteries: A Review

Abstract

Owing to their huge specific surface area, high porosity, abundant metal active sites, adjustable structure, and tunable pore diameters, metal-organic frameworks (MOFs) have attracted much attention from the battery scientists and technologists. MOFs have proven to be versatile precursors of cathode materials for batteries, and MOF-based cathodes have already exhibited excellent electrochemical performances. Herein, we review some recent advances in developing MOF-derived cathodes for lithium-/sodium-ion batteries, lithium-sulfur batteries, lithium-air batteries, and lithium-selenium batteries. We also describe the synthetic mechanism, characterization of MOF-derived cathodes, and the origin of the enhanced electrochemical performances. Finally, we point out some challenges and opportunities for the future development of MOF-based cathodes.

Metal–Organic Frameworks and Their Derivatives: Designing Principles and Advances toward Advanced Cathode Materials for Alkali Metal Ion Batteries

“…So far, many MOF-derived anode materials have been reported with improved electrochemical performance, while few materials were developed for cathodes, as shown in Table 2. [50] The organic ligands of MOFs can be transformed into carbon through calcination, while the metal ions can be used to construct metal-based compounds, such as metal sulfides, [51] oxides, [52] and phosphates. [53] The atomically homogenous structure promises a highly uniform distribution between the metal-based compounds and carbon, thus enhancing the rate performance and cycling stability, particularly for those electrode materials with large volume changes.…”

“…[ 63 ] Based on these benefits of MOFs, in the past two years, researchers have investigated various MOFs and their modified materials for M–S battery systems. [ 63,64 ]…”

Unveiling the physiochemical aspects of the matrix in improving sulfur-loading for room-temperature sodium–sulfur batteries

“…123 Another potential solution to entrap or confine sulfur in a microporous 3D matrix can be achieved by engineering networks derived from metal organic frameworks (MOF). [124][125][126] MOFs are a group of porous crystalline materials assembled by combining metal ions or clusters coordinated with organic linkers to form a highly ordered-porous spatial network. [127][128][129][130] Wei's group pioneered the use of microporous carbon/sulfur as a 3D matrix for the sulfur cathode.…”
