Abstract Hard carbon (HC) materials are suitable anodes for sodium‐ion batteries (SIBs) but still suffer from insufficient initial Coulombic efficiency (ICE). Promoting sodium storage via the pore filling mechanism is an effective way to improve ICE, and key here regulating structures of HC. In this work, coal‐derived HC successfully engineered with abundant accessible closed nanopores by treating coal precursors a facile destructive oxidation strategy. Investigations demonstrate that strategy can not only introduce oxygen‐containing functional groups (OFGs) also decrease size graphitic microcrystals. Thus, OFGs significantly enhance crosslinking small microcrystals stimulate formation during carbonization, which eventually improves ICE promoting mechanism. The optimized exhibits so far highest (92.2%) among SIB anode materials, together considerable capacity 328.5 mAh g −1 at 90 mA retention 95.1% after 150 cycles. results provide guidelines developing high‐performance toward large‐scale application SIBs, great significance future energy systems.

High‐abundance and low‐cost anodes for sodium‐ion batteries

Carbon Neutralization, Год журнала: 2024, Номер unknown

Опубликована: Сен. 27, 2024

Abstract Nowadays, sodium‐ion batteries are considered the most promising large‐scale energy storage systems (EESs) due to low cost and wide distribution of sodium sources as well similar working principle lithium‐ion (LIBs). Therefore, screening suitable materials with high abundance, cost, excellent reliability modified different strategies based on them is key point for development (SIBs). In addition, ideal anodes elements also greatly influence SIB systems, determining application. Herein, recent advances in carbon, iron, manganese, phosphorus‐based various types, such hard iron oxides, manganese red phosphorus, highlighted. The mechanisms structure‐function properties these four types summarized analyzed detail. Considering commercial profits that EESs can bring their suitability mass electrode manufacturing, participation high‐abundance low‐cost Fe, Mn, C, P convincing encouraging.

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

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Апрель 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.
