Sodium-ion batteries (SIBs) have caught considerable attention in last few years owing to the abundance of sodium in comparison to lithium. The commercial graphite anode is demonstrated unsuitable as an anode material for SIBs due to the larger radius of Na ions, whereas the transition metal dichalcogenides (TMDs) show great potential as anodes for SIBs because of their high achievable capacity. The sluggish kinetics, large volume expansion, and aggregation of those materials however results in severe decay of the electrochemical performance. In this work, a flower-like MoSe /C composite is synthesized with ethylenediamine and cassava starch (denoted as MoSe /C ) and designed based on these principles: 1) expand the d-spacing of (0 0 2) planes of MoSe to enhance the kinetics for the intercalation-deintercalation of Na ions and 2) embed MoSe into the carbon matrix to enhance the conductivity and restrict the volume expansion and aggregation of MoSe . As a result, MoSe /C exhibits superior cycle performance and rate capability for sodium storage. It shows durable long-life cycle capability with a reversible capacity of 360 mAh g after 350 cycles at 0.5 Ag . At the current density of 4 Ag , the reversible capacity is still maintained at 266 mAh g .

Lithium–sulfur (Li−S) batteries are one of the most promising candidates for the next generation of energy‐storage devices owing to their high theoretical energy and low cost. However, low practical energy density and poor cycling life are obstacles to the practical application of Li−S batteries. A highly conductive and lightweight poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate–carbon nanotube (PEDOT:PSS‐CNT) interlayer for Li−S batteries has been fabricated. The PEDOT:PSS‐CNT interlayer not only acts as a soft buffer to scavenge excess lithium polysulfides in the pores and restricts polysulfides from migrating to the lithium anode by chemical absorption, but also serves as an assisted “current collector” to improve the electronic conductivity for the sulfur cathode. With these synergistic contributions, pure sulfur cathode with the PEDOT:PSS‐CNT interlayer shows a high capacity (921 mA h g−1at 0.5 C; 1 C=1675 mA h g−1), enhanced cycling performance (a capacity retention of 70.9 % after 200 cycles), and good rate performance. The excellent electrochemical performance of the sulfur cathode plus the easy fabrication of such a functional interlayer bring feasible Li−S batteries for practical applications one step closer.

Meanwhile, heteroatom‐doped carbon within interlayer can also play an important role in improving sulfur electrochemical behavior as the heteroatom dopants function as active sites for polysulfide adsorption and electrocatalysis . Thanks to high‐content sulfur‐ and oxygen‐containing groups, Zhou and coworkers reported a sulfur‐doped microporous carbon (SMPC) interlayer by the carbonization of luffa sponge .…”

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.
