Thermochemical Core-Shell Architecturing of Si-SWCNT Composites for High-Performance Li-Ion Battery Anodes. [PDF]

Adv Sci (Weinh)
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si
