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. Combined N, co‐doped porous carbon matrix, optimal sample delivers excellent capability 381 mAh g −1 at 10 A performance (448 after 500 cycles 1 ). Furthermore, assembled full‐cells also exhibit superior electrochemical 87.5% capacity retention long‐term evaluations. This work presents promising strategy structural regulation sulfides advanced anodes SIBs.

Gas Generation in Lithium-Ion Batteries: Mechanisms, Failure Pathways, and Thermal Safety Implications

Batteries, Journal Year: 2025, Volume and Issue: 11(4), P. 152 - 152

Published: April 13, 2025

Gas evolution in lithium-ion batteries represents a pivotal yet underaddressed concern, significantly compromising long-term cyclability and safety through complex interfacial dynamics material degradation across both normal operation extreme thermal scenarios. While extensive research has focused on isolated gas generation mechanisms specific components, critical knowledge gaps persist understanding cross-component interactions the cascading failure pathways it induced. This review systematically decouples at cathodes (e.g., lattice oxygen-driven CO2/CO high-nickel layered oxides), anodes stress-triggered solvent reduction silicon composites), electrolytes (solvent decomposition), auxiliary materials (binder/separator degradation), while uniquely establishing their synergistic impacts battery stability. Distinct from prior modular analyses, we emphasize that: (1) emerging systems exhibit fundamentally different thermodynamics compared to conventional materials, exemplified by sulfide solid releasing H2S/SO2 via unique anionic redox pathways; (2) crosstalk between components creates compounding risks—retained gases induce electrolyte dry-out ion transport barriers during cycling, combustible gas–O2 mixtures accelerate runaway chain reactions. proposes three key strategies suppress generation: oxygen stabilization dopant engineering, decomposition mitigation tailored interphases (3) gas-selective adaptive separator development. Furthermore, establishes multiscale design framework spanning atomic defect control pack-level management, providing actionable guidelines for engineering. By correlating early detection metrics with patterns, work enables predictive standardized protocols, directly guiding development of reliable high-energy electric vehicles grid storage.
