“…The electrode materials, moreover, have insulating properties and exhibit massive volumetric expansion during redox reactions, which impedes the commercialization of Li S batteries. 16,17 Metal-organic frameworks (MOFs) are structured materials assembled by the coordination of inorganic clusters or ions with organic ligands. Since the pioneering work of Yaghi et al, a wide variety of MOFs with different compositions and structures have been reported.…”

Metal-organic framework (MOF) and their derivatives have been considered a promising material in the field of energy storage and conversion systems. Their distinct properties, including high porosity, tunable composition, and structure, enable the design of materials with tailored properties for achieving high performance. Lithium sulfur (Li S) batteries have several issues that prevent their broad application, including the low conductivity of sulfur, presence of soluble intermediates, and slow redox kinetics. MOF-based materials are a synthetic platform that is well positioned to mitigate these issues. This review highlights three essential function of Li S batteries and classifies recently developed MOF-based materials with respect to these functions. The design principles identified by such function-based classification provide guidance and perspective to rationally design MOF-based materials for advanced Li S batteries.

“…High conductivity, appropriate porosity and high mechanical strength are essential for nanostructured sulfur host materials [7]. Various carbon materials, for instance microporous carbon [8], mesoporous carbon [9], hierarchical porous materials [10], carbon nanotubes [11,12] and carbon fibers [13], have been used as host materials of sulfur in Li-S batteries. However, the weak interaction between polar lithium polysulfides and non-polar porous carbon materials could still results in severe shuttle effect, e.g., the irreversible loss of lithium polysulfides from electrodes and therefore significant decay of Li-S battery over long-term cycling [14].…”

Alleviating shuttle effect is vital to improve the electrochemical performance of lithium-sulfur (Li-S) batteries. Herein a nanosheet-like porous carbon (NSPC) with unique hierarchically porous structure and excellent electrical conductivity was synthesized as a host material of cathode, and highly-dispersed, electrochemically active CeO 2 nanoparticles as well as sulfur was deposited onto NSPC subsequently through supercritical CO 2-assisted processing to fabrticate CeO 2 decorated porous carbon/sulfur (C/CeO 2 /S) composites. In testing Li-S batteries, the C/CeO 2 /S material shows an initial capacity of 1538 mAh g −1 at 0.1 C, higher than that of C/S (1194 mAh g −1). The material also exhibits excellent cycling stability (~ 729 mAh g −1 at 0.5 C after 300 cycles). The gas-like viscosity, diffusivity and surface tension of supercritical CO 2 , facilitate highly dispersed loading of CeO 2 and sulfur on porous carbon with less agglomeration and more intimate contact with carbon to achieve higher conductivity and utilization efficiency. Moreover the electrocatalytic material CeO 2 promotes and stabilizes the redox reaction of polysulfide species.

“…Oriented material designs have been deemed as one of effective strategies to address the aforementioned challenges and promote the development of advanced lithium (Li) batteries for practical application. [9][10][11][12][13][14][15] Naturally biomass materials always exist in the form of biological macromolecules or carbohydrate compounds in plant or animal cells, which endow themselves with diverse microstructures, complex compositions, and abundant functional groups. These unique physicochemical properties offer an emerging opportunity to compatible with high-energy advanced lithium batteries.…”

Biomass materials are of great interest in high‐energy rechargeable batteries due to their appealing merits of sustainability, environmental benefits, and more importantly, structural/compositional versatilities, abundant functional groups and many other unique physicochemical properties. In this perspective, we provide both overview and prospect on the contributions of biomass‐derived ecomaterials to battery component engineering including binders, separators, polymer electrolytes, electrode hosts, and functional interlayers, and so forth toward high‐stable lithium–ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and solid state lithium metal batteries. Furthermore, based on the multifunctionalities of bio‐based materials, the design protocols for battery components with desired properties are highlighted. This perspective affords fresh inspiration on the rational designs of biomass‐based materials for advanced lithium‐based batteries, as well as the sustainable development of advanced energy storage devices.
