“…[ 29,30 ] It has also been shown that, apart from the planar graphitic layers, curved and rumpled domains are present in hard carbon systems. [ 9,38–44 ] To fully understand the effect of carbon structure on metal storage mechanisms, it is important to have an atomic scale study to bring insight into how the different isolated local carbon structures influence metal adsorption, binding, and migration, to further develop and commercialize these battery technologies.…”

Hard carbons are among the most promising materials for alkali-ion metal anodes. These materials have a highly complex structure and understanding the metal storage and migration within these structures is of utmost importance for the development of next-generation battery technologies. The effect of different carbon structural motifs on Li, Na, and K storage and diffusion are probed using density functional theory based on experimental characterizations of hard carbon samples. Two carbon structural models-the planar graphitic layer model and the cylindrical pore model-are constructed guided by small-angle X-ray scattering and transmission electron microscopy characterization. The planar graphitic layers with interlayer distance <6.5 Å are beneficial for metal storage, but do not have significant contribution to rapid metal diffusion. Fast diffusion is shown to take place in planar graphitic layers with interlayer distance >6.5 Å, when the graphitic layer separation becomes so wide that there is negligible interaction between the two graphitic layers. The cylindrical pore model, reflecting the curved morphology, does not increase metal storage, but significantly lowers the metal migration barriers. Hence, the curved carbon morphologies are shown to have great importance for battery cycling. These findings provide an atomic-scale picture of the metal storage and diffusion in these materials.

“…Commonly investigated anode materials are, e.g., hard carbons and TiO 2 , which exhibit a good overall electrochemical performance. Nevertheless, the limited gravimetric capacity of TiO 2 as well as the limited volumetric capacity of hard carbons, and the somehow high initial irreversible capacity of both materials are big challenges that need to be addressed.…”

Silicon‐based compounds are interesting candidate anode materials but show only relatively low electrochemical performances with sodium. Controversial reports are available about the electrochemical interaction between Na and silicon, which encourage to investigate the mechanism in a silicon‐based material in detail. This study reports the results of a systematic investigation of the electrochemical sodium ion storage in silicon oxycarbide (SiCO) using ex situ X‐ray photoelectron spectroscopy and magic‐angle spinning nuclear magnetic resonance spectroscopy. Comparison of pristine and hydrofluoric acid‐etched silicon oxycarbide shows that the silicon oxycarbide is active itself, but not by an alloying process. Instead, results reveal an irreversible structural change and amorphization of SiCO upon the initial sodium uptake and support the existence of reversible insertion‐based reactions in the subsequent cycles.

“…Host materials featuring highly porous structure and large surface area can allow sufficient space to encapsulate the electrode active phase and abundant active electrode/electrolyte interface for promoting reversible electrochemical conversions. Meanwhile, high porosity can enhance Li ion transport kinetics within the electrode, which should also be emphasized in the design of conductive carbon matrix . Zhong and coworkers developed a puffing process to produce porous carbon (PRC) as a sulfur cathode host derived from rice (Figure A) .…”

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.
