Electrochemical Impedance Spectroscopy‐Based Diagnosis of Cell Imbalances in Series‐Connected Battery Modules

open access: yesBatteries &Supercaps, EarlyView.
This study extends electrochemical impedance spectroscopy (EIS) to battery module level to detect state of charge (SOC) and state of health (SOH) imbalances among series‐connected cells. By comparing single‐point diagnostics with Pearson correlation and support vector machine (SVM) classification, the results demonstrate the potential of advanced ...

A New Three‐Dimensional Microstructure‐Resolved Model to Assess Mechanical Stress in Solid‐State Battery Electrodes

open access: yesBatteries &Supercaps, EarlyView.
Electrochemical–mechanical coupling in a 3D‐resolved microstructure of a solid‐state battery electrode. In all‐solid‐state batteries (ASSBs), the mechanical stress generated during electrode (de)lithiation plays a critical role in determining the cell longevity because of the induced degradation mechanisms.

Analyzing the Impact of Electrolyte Motion Induced Salt Inhomogeneity Effect on Apparent Aging: Role of Current Rates and Temperature Effects in Accelerated Cyclic Aging Tests in Li‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Lithium‐ion batteries subjected to accelerated cycling can display recoverable capacity loss unrelated to real lifetime. This study explains the origin through loss of homogeneity of lithium distribution in the anode and salt concentration in the electrolyte.

Excited‐State Proton Transfer in Push‐Pull N‐Methyl Pyridium Reversible Super‐Photoacids Ruled by Intramolecular Hydrogen‐Bond‐Like Interactions

open access: yesChemistry – A European Journal, EarlyView.
Push‐pull A+‐π‐D N‐methyl pyridinium derivatives were found to act as efficient reversible superphotoacids. Upon excitation, they undergo a fast ESPT but recombine with the released proton when the excitation is turned off. In the ortho isomers, intramolecular hydrogen‐bond‐like interactions between the hydroxyl group and the ethenic hydrogen are ...

Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Unveiling the Electrochemical Reversibility of Multielectron Redox in s‐Tetrazine Derivatives for Large‐Capacity Electrode Materials

open access: yesChemSusChem, EarlyView.
Peripheral 2‐pyridine rings delocalize charges by withdrawing electrons and, through Li‐ion coordination in the reduced state, lock the geometry of the s‐tetrazine core. This stabilization markedly enhances redox kinetics and Li‐ion diffusion, enabling electrochemically reversible two‐electron transfer of s‐tetrazine derivatives.
