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.

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.
