Unveiling Hidden Patterns in Electrode‐Electrolyte Interphase Chemistry and Architecture Through Machine Learning‐Assisted Mass Spectrometry Analysis

Electrode-electrolyte interphases (EEIs) govern battery performance, yet the interplay between their chemical composition and spatial organization remains challenging to resolve. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) provides rich 3D chemical depth profiles of...

High-Voltage Sodium–MetalBatteries with AsymmetricFluoroalkoxylated Organoborate Anion Chemistry

Abstract The high reactivity of sodium (Na) metal restricts its compatibility to ether-based electrolytes, while the poor oxidative stability of ethers precludes their coupling to high-voltage cathodes, fundamentally limiting the operating voltage and energy density of sodium–met...
