Tailoring Oxide/MAX Phase Nanocomposites via Low-Temperature Oxidation for Lithium-Ion Battery Anodes: Peeking Behind the Electrochemical Mechanism via In Situ Investigations. [PDF]

open access: yesAdv Sci (Weinh)
Controlled oxidation of Ti3Al0.3Sn0.7C2 produces SnO2/TiO2–MAX nanocomposites with superior electrochemical performance. The SnHigh_Ox700 sample shows optimal stability, capacity (300 mAh g−1), and reversibility (99.2%). Its unique morphology ensures efficient charge transport and stress accommodation. In situ analyses reveal reversible SnO2 conversion/
