Abstract Sodium‐ion hybrid capacitors (SIHCs) represent a promising option for cost‐effective grid‐scale energy storage due to their combination of high and power densities, as well excellent cycle stability. However, the practical application SIHCs is hindered by lack advanced anode materials that exhibit fast ion diffusion kinetics robust structures. Herein, novel design featuring nano‐sized Fe 3 O 4 developed, double‐reinforced porous carbon derived from metal‐organic frameworks (MOFs) inner core support N, P‐co‐doped polymer decomposition outer shell, resulting in pencil‐like core–shell structural composite (Fe /NPC). The nanograins abundant surface groups containing N P reduce charge/electron transfer distance provide numerous pseudocapacitive active sites, guaranteeing output superior rate capability. optimized structure interconnected framework effectively accommodate volume changes, prevent nanoparticle agglomeration, facilitate ion/electron transport, thereby ensuring integrity rapid kinetics. In testing, /NPC demonstrated cycling durability, retaining 86.6% its initial capacity after 2500 cycles sodium‐ion batteries (SIBs). Impressively, assembled SIHC achieved notable density 147.1 W h kg −1 maintained 92% 8000 cycles.

Abstract Rationally designing the electrolyte system toward improving electrochemical performance, especially rate capability, of sodium ion batteries (SIBs) is very important for accelerating their large‐scale commercialization. Herein, it shown that by refining molar ratio two ether solvents, namely dimethoxyethane (DME) and 2‐methyl tetrahydrofuran (MeTHF), a binary solvent forms solvation structure facilitates high charge/discharge hard carbon (HC) electrodes. It demonstrated boosted capability can be attributed to enhanced transportation desolvation kinetics, resulting from participation weak‐coordinating MeTHF molecule with low steric hindrance in sheath, which weakens interaction between molecules/anions through electron density regulation at bond critical points (BCPs). The thin uniform solid interphase film on HC electrodes formed such an ether‐based also beneficial performance cycling stability. results present study shed more light how engineering BCPs sheath affects promote its practical application prospect future sodium‐based battery chemistries.

Engineering Alkali Lignin Structure Modification: Enhanced Hard Carbon Electrolyte Interface Toward Practical Sodium Ion Batteries

Small, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Hard carbon (HC) exhibits great potential as a promising candidate for sodium-ion batteries owing to its inherent advantages. However, the main challenges in utilizing HC stem from low initial coulombic efficiency (ICE) and poor rate performance caused by excessive surface defects. In this study, an effective strategy of employing alkali lignin (AL) is proposed, derived pulp waste, binder create uniform inorganically enriched solid electrolyte interface. AL can modify defects through strong π-π interactions between aromatic ring HC, while ingeniously grafting abundant active ─OH ─COOH groups onto electrode surface. The force salts facilitates formation ultra-thin NaF-rich interface (SEI) layer (10 nm), thereby achieving exceptional ICE 91%. Furthermore, electrochemical activity, enables anode exhibit increasing slope capacity during cycling, compensating decay at high current densities. Consequently, when assembled into full battery configuration, excellent achieved with reversible 282 mAh g-1 even density 5A g-1.
