Advanced Energy Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 6, 2024

Abstract Electrodes are vital for lithium‐ion battery performance. The primary method large‐scale electrode production involves wet slurry casting methods, which encounter challenges related to solvent usage, energy consumption, and mechanical stability. Dry processed (DP) electrodes a promising alternative but struggle with rate capability properties. Here, an approach of incorporating 1 wt.% flour into DP (DP–1%F) through binder fibrillation strategy is introduced, enhances the strength, performance, cycling stability electrodes. cross‐linking protein starch in flour, along Polytetrafluoroethylene (PTFE), enable DP–1%F exhibit robust properties high flexibility. Additionally, incorporation makes primarily create large pores, reducing tortuosity, thereby endowing improved kinetic behavior. behavior suppress development irreversible phase transitions intragranular/intergranular cracks. These characteristics led superior capacity retention 80.3% after 260 cycles at 2C 4.5 V (LiNi 0.8 Co 0.1 Mn O 2 ). findings offer valuable insights high‐power, long‐life electrodes, addressing key batteries.

Carbon Neutralization, Год журнала: 2025, Номер 4(1)

Опубликована: Янв. 1, 2025

ABSTRACT In military reserve power supplies, there is an urgent need for superior secondary batteries to replace conventional primary batteries, and lithium‐ion (LIBs) emerge as one of the best choices due their exceptional performance. The life LIBs includes cycle calendar life, with spanning from years decades. Accurate prediction crucial optimizing deployment maintenance in applications. Model‐based prognostics are usually established estimate using accelerated aging methods under various storage conditions. This review firstly outlines general prognostic workflow LIBs, analyzes degradation mechanisms, summarizes influencing factors; then, we introduce models, evolving simplistic empirical models (EMs) nonempirical mechanistic (MMs) based on LIB knowledge then traditional hybrid empirical‐mechanistic (trad‐EMMs). Finally, data‐driven (DDMs) machine learning (ML) discussed limitation methods, pure knowledge‐integrated establishing a comprehensive framework assessment. To our knowledge, this paper presents first field, summarizing offering some insights into future model development directions. can facilitate researchers analysis prolongation, thereby better serving application national economic life.

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

Batteries, Год журнала: 2025, Номер 11(4), С. 152 - 152

Опубликована: Апрель 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.

Abstract Global interest in lithium–sulfur batteries as one of the most promising energy storage technologies has been sparked by their low sulfur cathode cost, high gravimetric, volumetric densities, abundant resources, and environmental friendliness. However, practical application is significantly impeded several serious issues that arise at cathode–electrolyte interface, such interface structure degradation including uneven deposition Li 2 S, unstable interphase (CEI) layer intermediate polysulfide shuttle effect. Thus, an optimized along with electrodes required for overall improvement. Herein, we comprehensively outline challenges corresponding strategies, electrolyte optimization to create a dense CEI layer, regulating S pattern, inhibiting effect regard solid–liquid–solid pathway, transformation from solid–solid pathway interface. In order spur more perceptive research hasten widespread use batteries, viewpoints on designing stable deep comprehension are also put forth.
