Abstract

Carbon-based materials are considered promising anode candidates for sodium-ion batteries. However, previous research has rarely investigated the impact of carbon's microcrystalline structure on its sodium storage. This study designed carbon materials with a unique structure, which significantly reduces the influence of variations in specific surface area, pore structure and interlayer spacing on sodium storage, making them ideal for investigating the effect of microcrystalline structure on electrochemical performance. The combination of first-principles density functional theory (DFT) calculations, electrochemical experiments, and characterizations confirms that BC-800 with the smallest L_a and the highest disorder degree, exhibits superior reversible capacity, rate performance, and long-term cycle stability.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
