Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.

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 ...

The Origin of Improved Performance in Boron‐Alloyed Silicon Nanoparticle‐Based Anodes for Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon‐boron alloy nanoparticles are incorporated into lithium‐ion batteries as the active anode material and enhance the battery cycle and calendar lifetime with improved interfacial chemical passivation. This passivation is afforded by the strong surface dipoles imparted on the particles from Lewis acidic surface boron.
