Promoting Robust and Rapid Na‐Ion Storage of Molybdenum‐Based Sulfide via Rational Hetero and Hollow Structure Design

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

Abstract Molybdenum disulfide (MoS 2 ), characterized by its two‐dimensional structure and high theoretical specific capacity, is considered a prospective anode of Na‐ion battery. However, the cycling rate capabilities are hampered sluggish charge transfer kinetics poor structural stability. To overcome issues, most efforts have been focused on optimizing MoS . Nevertheless, rationally designing that can present rapid durable storage while ensuring large remains challenges. Herein, /MnS heterostructure featuring sphere‐like hollow morphology designed according to Ostwald ripening process Kirkendall effect. This construction effectively establish an interfacial built‐in electric field activated MnS , which exhibit P‐type N‐type semiconductor characteristics, respectively, thereby promoting electrochemical kinetics. Moreover, excellent stability after repeated (de)sodiation processes remarkably achieved thanks robust design, significantly achieving outstanding tolerance changes. Consequently, delivers capacity (594.8 mAh g −1 at 0.1 A superior performance (up 100 ultrastable capability (30 000 cycles with ≈81.4% retention). The work affords effective optimization tactic develop high‐performance conversion‐type electrodes for alkali‐ion batteries.

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.
