Abstract The bimetallic synergies effect and combined conversion/alloying mechanism endow thiospinel FeIn 2 S 4 with great potential as an anode material for sodium‐ion batteries (SIBs). However, their inconsistent synthesis, severe volumetric expansion, sluggish reaction kinetics typically lead to unsatisfactory cyclic stability rate capability. Herein, organic framework derived @N/S‐C microrods Fe vacancies is presented fast, durable, reversible sodium storage. presence of significantly modulates the d ‐band center decreases strength Fe─S bond facilitating sodiation jointly. Moreover, a thin stable solid electrolyte interface film inorganic‐rich components formed by induction.

Sustainable Carbon‐Based Catalyst Materials Derived From Lignocellulosic Biomass for Energy Storage and Conversion: Atomic Modulation and Properties Improvement

Carbon Energy, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.

Nitrogen-Doped Fullerene C₆₀ as High-Performance Anodes for Sodium-Ion Batteries: Enhanced Sodium Adsorption and Storage Capacity

The Journal of Physical Chemistry Letters, Journal Year: 2025, Volume and Issue: unknown, P. 1753 - 1759

Published: Feb. 10, 2025

As the need for sustainable energy storage grows, sodium-ion batteries (SIBs) present a promising alternative to lithium-ion due abundance and low cost of sodium. We explored electrochemical properties nitrogen-doped fullerene (C57N3) as an anode material SIBs via first-principles calculations. The results show that nitrogen doping reduces band gap C60 tunes charge distribution C60, which optimizes adsorption Na with -2.13 eV diffusion barrier only 0.105 eV, suggesting improved capacity rate performance. Eventually, theoretical calculations demonstrate sodium 332.20 mAh/g C57N3, in comparison value 223.40 C60. These findings highlight potential C57N3 future SIB applications.
