The implementation of sodium-ion batteries for renewable energy storage requires the development sustainable electrode materials. Usually, these materials are produced through complex energy-intensive processes that challenging to scale and involve expensive and/or toxic reagents. In this study, hard carbon materials, some doped with iron, synthesized from sucrose using a simple, fast, cost-effective two-step eco-friendly process, investigated as anodes batteries. influence physicochemical structural material properties on reversible capacity, cycling stability, efficiency is analyzed. SC900 material, which exhibits certain graphite-like structure, though not strictly graphitic, showed best electrochemical performance, providing discharge capacities exceeding 100 mAh g-1 after 400 cycles excellent stability high coulombic efficiency. capacity increases d002 decreases, (i.e., degree order increases), optimum value ~0.3700 nm. However, further decrease in values characteristic quasi-graphitic consequence catalytic effect hinders Na+-ion storage, which, addition low activity iron oxides present, leads much lower capacities.

Bridging Structure and Performance: Decoding Sodium Storage in Hard Carbon Anodes

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

Amorphous carbon, particularly hard carbon (HC), is widely considered as the most promising anode material for sodium-ion batteries (SIBs) due to its high reversible capacity and cost-effectiveness. However, complex poorly defined structural properties of HC present challenges in understanding underlying sodium storage mechanisms. To facilitate rational design high-performance anodes, a comprehensive correlation between microstructure behavior critical. This Review critically examines interplay features capabilities, focusing on two key factors: pore structure surface functional groups. It begins by outlining fundamental mechanisms HC, followed an in-depth discussion how chemistry influence storage. Finally, strategic insights are provided manipulate these factors optimize performance. aims drive development next-generation anodes support commercialization SIBs.

State change of Na clusters in hard carbon electrodes and increased capacity for Na-ion batteries achieved by heteroatom doping

Carbon Trends, Journal Year: 2024, Volume and Issue: 16, P. 100387 - 100387

Published: July 27, 2024

Although heteroatom doping is an effective method to improve the capacity of hard carbon (HC) anodes in Na-ion batteries (NIBs), complicated structure HC leads uncertainty when understanding effects on sodium storage. This study shows phosphorus and sulfur storage using solid-state NMR prepared by carbonization resorcinol formaldehyde (RF) resin at 1100 °C. Heteroatom increased battery HC, especially plateau capacity, but interlayer distance layers did not expand considerably. 23Na revealed that facilitates formation quasi-metallic clusters, thereby contributing increase. The metallicity clusters heteroatom-doped samples was controlled amount doped-phosphorous. XPS 31P detected various sites such as phosphine oxide structure.

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(20), P. 9543 - 9550

Published: Oct. 16, 2024

Biowaste-derived carbons store large amounts of sodium as many competing reactions adsorption, intercalation, and pore filling take place. Herein, we report electron paramagnetic resonance (EPR) spectroscopy a comprehensive method to monitor the interaction with used electrodes in sodium-ion cells. It is shown that EPR can distinguish signals due intercalation cluster growth. Applying correlation between line width metallic particle dimension, clusters are quantified regarding their size. In terms EPR, discuss sodiation mechanism storage performance derived from spent coffee grounds. The smallest (below 2 nm) formed on closed-pore at potential 0.01 V, while largest (around 200 occur hydrogen-rich 0.05 V earliest. small generated around give extra capacity, occurring 0.5 0.1 ensures good cycle stability.
