Highly Robust Sn‐Based MAX Anodes Constructed via Ti6C Octahedral Outer Immobilization and A‐Layer Fe Inner Anchoring for Long‐Life Lithium‐Ion Batteries

Advanced Science, EarlyView.
How can Sn‐based anodes achieve high capacity and long‐life cycling? This work unlocks the potential anode structure by confining Sn in the A layer of MAX phase with Ti6C octahedra as outer immobilization and Fe as inner anchors. The introduction of Fe dramatically strengthens the Ti–Sn bond to enhance structural integrity, modulate interfacial ...

Multiscale Carbon‐Integrated Silicon Anode for Stable Cycling Under Practical Lithium‐Ion Battery Conditions

Advanced Energy Materials, EarlyView.
To overcome silicon anode instability, a hierarchical silicon/carbon composite fabricated from industrial waste via a scalable milling process is demonstrated. In‐depth post‐mortem analysis reveals how functional carbons—a CNT network and graphene shell—synergistically suppress degradation. This robust design delivers outstanding stability in practical
