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.

Rechargeable batteries with high durability over wide temperature is needed in aerospace and submarine fields. Unfortunately, Current battery technologies suffer from limited operating temperatures due to the rapid performance decay at extreme temperatures. A major challenge for wide-temperature electrolyte design lies restricting parasitic reactions elevated while improving reaction kinetics low Here, we demonstrate a temperature-adaptive by regulating dipole-dipole interactions various simultaneously address issues both subzero This approach prevents degradation endowing it ability undergo adaptive changes as varies. Such favors form solvation structure thermal stability rising transits one that salt precipitation lower ensures stably within range of ‒60 −55 °C. opens an avenue design, highlighting significance structures. High instability sluggishness electrolytes pose significant barriers towards sodium-ion batteries. authors report

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.

Abstract Sodium‐ion batteries (SIBs) hold tremendous potential in next‐generation energy storage. However, no SIB has yet achieved simultaneous support for high voltage, rapid charging, and all‐climate adaptability due to electrolyte limitations. This study successfully constructs versatile SIBs using an optimized acetonitrile (AN)‐based electrolyte, which offers excellent high‐voltage tolerance, ionic conductivity, anion‐enriched solvation structure, a wide liquidus temperature range. The engineered solid interphase (SEI) exhibits low resistance exceptional stability, effectively supporting fast temperature‐adaptive operation, long‐term cycling stability. Consequently, this tailored combined with robust SEI, enables hard carbon (HC) anodes achieve reversible capacity of 223 mAh g −1 at rate 5 C. When paired NaNi 1/3 Fe Mn O 2 (NFM) cathode, the HC||NFM full cells operate stably cut‐off voltage 4.15 V, sustaining over 1400 cycles Furthermore, practical 3 Ah pouch cell demonstrates retaining 90.7% its after 1000 cycles, shows adaptability, maintaining 56.4% room‐temperature −60 °C 97.3% retention 350 50 °C. work provides valuable insights developing advanced electrolytes SIBs.
