Flaky sputtered silicon MWCNTs core-shell structure as a freestanding binder-free electrode for lithium-ion battery.

ABSTRACT: Core-shell silicon/multiwall carbon nanotubes are one of the most promising anode candidates for further improvement of lithium-ion batteries. Sufficient accommodation for massive volume expansion of silicon during the lithiation process and preventing pulverization and delamination with easy fabrication processes are still critical issues for practical applications. In this study, core-shell silicon/MWCNTs anode materials were synthesized using a facile and controllable PECVD technique to realize aligned MWCNTs followed by a silicon sputtering step. The use of the PECVD technique and the direct growth of multi-walled carbon nanotubes on the current collector creates a low tortuosity, flexible, and conductive scaffold, which, in addition to preventing CNT agglomeration, alleviates the pulv
