“…Good electrical contact with sufficient conductive additives might be necessary to facilitate a smooth conversion of sulfur . A further improved redox kinetics of sulfur cathode could be realized by applying various electrocatalysts (e.g., metals,107a,b,108 metallic compounds,107c–e,109 and polar materials108,109b) in the sulfur cathode as redox mediators. These mediators possess high catalytic activity, which enable sulfur to exhibit enhanced conversion efficiency and stability .…”

that makes use of intercalation materials as the electrodes (Figure 1), applications involving electric vehicles and smart grids may require rechargeable batteries with new battery chemistries that can generate even higher energy densities for longer driving ranges and higher energy-storage capabilities. [6][7][8] Additionally, the lithiated transition-metal oxides used in commercial lithium-ion battery cathodes tend to be expensive, scarce, or toxic to the environment. Thus, it is desirable to explore new electrode materials that are naturally abundant (and therefore less expensive) as well as environmentally compatible in order to successfully enter the future battery markets. [6,[8][9][10][11] This driving force has promoted the development of batteries with conversionreaction electrodes, in which reversible electrochemical reactions take place and new chemical compounds form during the cycling of the battery. Naturally abundant materials, such as sulfur for the cathode, can be applied as electrodes. Different metallic anodes have shown great potential in coupling with sulfur cathode to generate a high energy density, including lithium metal [3,10,[12][13][14][15][16][17]31] as well as other alkali [18][19][20][21][22][23][24]31] and high-valent metals. [18,[25][26][27][28][29][30][31] As a next-generation energy-storage technology beyond lithium-ion batteries, lithium-sulfur batteries are the most promising low-cost, high-capacity energy-storage device available due to their high charge-storage capacity, low cost, and the wide availability of sulfur. [32][33][34][35] The electrochemical reactions of lithium-sulfur batteries involve reversible conversions between sulfur (S 8 ), lithium polysulfides (Li 2 S x , x = 4-8), and lithium sulfides (Li 2 S 2 and Li 2 S). [33][34][35][36] The conversions between sulfur and lithium polysulfides and lithium sulfides involve phase changes between liquid-state polysulfides and solid-state sulfur and sulfides. [35][36][37][38][39][40] Thus, the conversion reaction of lithium-sulfur battery chemistry has no restriction in maintaining the initial crystal chemistry of the electrode during electrochemical cycling. [39][40][41][42] Therefore, a full twoelectron redox reaction per sulfur atom can occur in a manner that is both reversible and stable, increasing the chargestorage capacity drastically as compared to the currently used insertion-reaction oxide cathodes. [7,[39][40][41][42] As a result, sulfur cathodes possess a high theoretical charge-storage capacity of 1672 mA h g −1 , which is the highest value among solid-state Lithium-sulfur batteries are a major focus of academic and industrial energystorage research due to their high theoretical energy density and the use of low-cost materials. The high energy density results from the conversion mechanism that lithium-sulfur cells utilize. The sulfur cathode, being naturally abundant and environmentally friendly, makes lithium-sulfur batteries a potential next-generation energy-storage technology. The current state of the rese...

“…[2,14] Chemical adsorption can facilitate the uniform distribution of S and Li 2 S on the carbonaceous materials thereby ensuring strong electrical contact, and can efficiently alleviate the dissolution of LiPSs in the cathode. [19][20][21] To further increase the adsorption sites and catalysis for LiPSs, surface-defects-engineering has also been proposed due to the enriched surface electron of the hosts, which can achieve an efficient adsorption-catalysis synergy, and is regarded as an effective method to improve the electrochemical properties of nature compounds. Catalysts such as sulfides, oxides, and heterostructures can improve the reaction kinetics to reduce the accumulation of LiPSs in the Li-S battery, which contributes to alleviating the shuttle effect.…”

Lithium‐sulfur (Li‐S) batteries are one of the most promising next‐generation energy‐storage systems. Nevertheless, the sluggish sulfur redox and shuttle effect in Li‐S batteries are the major obstacles to their commercial application. Previous investigations on adsorption for LiPSs have made great progress but cannot restrain the shuttle effect. Catalysts can enhance the reaction kinetics, and then alleviate the shuttle effect. The synergistic relationship between adsorption and catalysis has become the hotspot for research into suppressing the shuttle effect and improving battery performance. Herein, the adsorption‐catalysis synergy in Li‐S batteries is reviewed, the adsorption‐catalysis designs are divided into four categories: adsorption‐catalysis for LiPSs aggregation, polythionate or thiosulfate generation, and sulfur radical formation, as well as other adsorption‐catalysis. Then advanced strategies, future perspectives, and challenges are proposed to aim at long‐life and high‐efficiency Li‐S 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.
