Assessing Mesoscale Heterogeneities in Hard Carbon Electrodes Through Deep Learning‐Assisted FIB‐SEM Characterization, Manufacturing and Electrochemical Modeling

open access: yesAdvanced Energy Materials, EarlyView.
A combination of discrete and finite element method models for the current collector deformation and electrochemical performance analysis, respectively. The models are calibrated and validated with electrochemical and imaging data of hard carbon electrodes. These electrodes were manufactured with different parameters (slurry solid contents of 35 and 40

One‐Step Radical‐Intensified Selective Etching (RISE) Strategy for High‐Yield Synthesis of Monolayer MXene with Tailored Nanoholes

open access: yesAngewandte Chemie, EarlyView.
Radical‐intensified selective etching (RISE) delivers monolayer MXenes with >80% yield in just 3 h etching process. Controlled ·OH dosage enables one‐step access to holey MXenes with abundant nanopores or defect‐lean flakes. This mild, safe strategy couple ultrafast kinetics with structural tunability, advancing precision design of MXene architectures.

Solvent‐Induced Covalent Bond Softening Boosts Battery Voltage

open access: yesAngewandte Chemie, EarlyView.
The strong attractive interaction between the nucleophilic center of the solvent and the electrophilic region of the covalently bonded cathode fragment triggers charge transfer. This results in the electron population in the antibonding orbital of the covalent bond, leading to bond weakening and elongation, and consequently increasing the cathode ...
