Advanced Functional Materials, Год журнала: 2024, Номер 34(44)

Опубликована: Май 20, 2024

Abstract In recent years, the penetration rate of lithium iron phosphate batteries in energy storage field has surged, underscoring pressing need to recycle retired LiFePO 4 (LFP) within framework low carbon and sustainable development. This review first introduces economic benefits regenerating LFP power development history LFP, establish necessity recycling. Then, entire life cycle process failure mechanism are outlined. The focus is on highlighting advantages direct recycling technology for materials. Directly materials a very promising solution. spent (S‐LFP) can not only protect environment save resources, but also directly add atoms vacancies missing repair S‐LFP At same time, simply supplementing simplifies recovery improves benefits. status various methods then reviewed terms regeneration process, principles, advantages, challenges. Additionally, it noted that currently its early stages, there challenges alternative directions

Abstract Li plating is widely known as the key factor leading to degradation and safety issues in lithium‐ion batteries (LIBs). Herein, feasibility of monitoring onset progression proposed justified graphite/LiFePO 4 pouch cell by an operando impedance‐thickness combinational technique. First, a proof‐of‐concept, real‐time thickness/impedance variations LIBs during charging at low temperature (≈0 °C) are obtained dissected. Three distinct stages corresponding different patterns observed with critical changing points charge‐transfer resistance, which match well counterpoints differential thickness/capacity curves. Post‐mortem analysis Mass Titration Scanning Microscopy also indicate that these intercalation, nucleation & nuclei growth, dendrite respectively. Thereafter, cycling protocols carried out test as‐mentioned processes this novel The results disclose extensive deposition metallic significantly intensifies loss inventory, aging or even “capacity plunge”, depict safer boundary plot about preventing occurrence “Li plating” region. This work provides new insights on behavior battery control under harsh operational conditions.

Flour‐Infused Dry Processed Electrode Enhancing Lithium‐Ion Battery Performance

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.

Quantitative Analysis of Aging and Rollover Failure Mechanisms of Lithium‐Ion Batteries at Accelerated Aging Conditions

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 5, 2025

Abstract Accurate quantification of the aging mechanisms batteries at accelerated conditions is great significance for lithium‐ion (LIBs). Here and rollover failure LiFePO 4 (LFP)/graphite different temperatures are investigated using a combination advanced techniques such as electrolyte methods, mass spectrometry titration (MST), time‐of‐flight secondary ion (TOF‐SIMS), Raman imaging. The growth, rapture, repair process solid interphase (SEI) primary mechanism leading to battery aging, its contribution increases with temperature. High temperature exacerbates decomposition (especially lithium salts), together organic SEI decomposing into more stable inorganic high temperature, resulting in thicker rich compositions. also lead spatially inhomogeneous side reactions, which may turn accelerate further degradation battery. sharp capacity decline, namely failure, primarily due depletion additive VC, shifts from VC solvents salts, rather than by increase internal resistance, plating, drying out, electrode saturation, or mechanical deformation.
