“…However, the typical peak of ACNI near 1380 cm –1 (D-band) and 1560 cm –1 (G-band) gradually appeared with the increasing ACNI deposition time from 10 to 60 min (Figures j and S4). ,− Besides, the deposited ACNI shows a photoluminescence background, indicating a certain amount of hydrogen. ,, According to the NEXAFS spectrum in the carbon k -edge (Figure k), the sp 3 /(sp 3 + sp 2 ) ratio of the deposited ACNI (deposited on the Si substrate for 60 min) is about 0.53, which belongs to the hydrogenated amorphous carbon. , The XRD patterns of both the coarsened Al and ACNI/Al-15 foil exhibit no other impurity phases (Figure S5).…”

Dual-ion batteries (DIBs) are one of the promising candidates to meet the low-cost requirements of commercial applications because of their high working voltage, excellent safety, and environmental friendliness. In addition to the electrolyte, the research on DIBs mainly focuses on the electrode materials, especially the high-performance anodes. Alloy-type materials, such as Si, Sn, Al, and so forth, are promising alternative anodes owing to their large abundance, excellent conductivity, and especially high specific capacity. However, the alloy-type anodes tend to pulverize due to the excessive volume expansion during the alloying/dealloying process, along with repeated growth/fracture of the solid electrolyte interphase (SEI) layer and continuous consumption of the electrolyte. Herein, we have successfully developed an amorphous carbon nanointerface (ACNI) (<10 nm) coated on an Al anode that acts as an artificial SEI to prevent the continuous growth of the formed SEI layer and maintain its structural stability. Further, pairing this ultrathin ACNI/Al anode with the graphite cathode constructs proof-of-concept DIBs, exhibiting significantly improved performances with a specific capacity of 115 mA h g −1 and a capacity retention ratio of ∼94% after 1000 cycles.

Polysulfide dissolution and shuttling limit the capacity output and cycle life of lithium−sulfur batteries to a great extent. Separator modification using polar materials exploiting the ability to entrap polysulfides has been demonstrated as an effective approach to deal with the conundrum of polysulfide shuttling. Herein, a carbon nanotube/manganese sulfide nanocomposite is designed as a separator modifier in lithium−sulfur batteries for the first time. Furthermore, the carbon nanotube network provides a continuous network for rapid electronic conduction, imparts structural stability, and acts as a secondary barrier for polysulfides. Consequently, the cell displays an initial discharge capacity of 876 mAh g −1 at 0.5 C and sustains excellent stability with a retained capacity of 76% after 500 cycles. The self-discharge of the cell is also conspicuously reduced, maintaining a constant voltage for 100 h under open-circuit conditions. The electrochemical results represent an effective strategy to realize better performing Li−S batteries.

Lithium‐sulfur (Li−S) batteries have attracted attention in the field of energy storage due to their high energy density and theoretical capacity. However, there are still some obstacles to achieve commercial applications such as large volume expansion of sulfur, low electrical conductivity, the growth of lithium dendrites, and the polysulfide shuttle effect. Through continuous research on Li−S batteries, renewable biomass materials have been discovered by scholars and scientists due to their sustainable development, low cost, and extensive sources. The results showed that renewable biomass‐derived carbons had outstanding advantages such as high specific surface area and large pore volume, as well as inherent heteroatom doping after being applied to Li−S batteries, which had a significant effect on improving the electrochemical performance. This Review summarizes the research progress of Li−S batteries in renewable biomass materials in recent years, starting from three aspects: biomass carbon‐sulfur composite cathodes, biomass modified separators, and biomass independent flexible carbon interlayers. Firstly, the Review summarizes its physical barrier and adsorption mechanism (the effect of various porous structures), chemical reaction and adsorption mechanism, catalysis and conversion mechanism. Then, it classifies materials based on the source of renewable biomass as well as elaborating and analyzing the structures, mechanism, and performance among them. Finally, the Review summarized the shortages in this field, as well as the challenges and opportunities faced. The authors hope that this Review will have a certain reference value for the development of various biomasses for high performance Li−S batteries, and will inspire more scholars to devote themselves to the research of biomass materials for Li−S batteries.
