Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

Single‐Atom Co Meets Remote Fe for a Synergistic Boost in Oxygen Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
A one‐step Coordination‐Selective Synthesis strategy enables the integration of Co‐N4 single‐atom sites with remote Fe‐based nanoparticles, optimizing electrocatalytic performance. Electrochemical tests confirm that Fe‐based nanoparticles enhance charge and mass transport, boosting reaction kinetics.

Scandium Induced Structural Disorder and Vacancy Engineering in Li3Sb – Superior Ionic Conductivity in Li3−3xScxSb

open access: yesAdvanced Energy Materials, EarlyView.
A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...

Unveiling the Impact of C60–O2 Interaction on the Performance and Characterization of Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.

Unique Na5−xSbSe Phase Enables High‐Rate Performance of Sb2Se3 Anodes in Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The (de)sodiation mechanism of Sb2Se3 is revealed through advanced operando techniques and ab initio simulations and underscores the value of complementary methods in exploring battery mechanisms. A new Na5−xSbSe phase is identified as the final sodiation product of Sb2Se3 anodes in Na‐ion batteries (NIBs), which enables the remarkably high‐rate ...
