Title:
Silicon-Carbon Nanotube Coaxial Sponge as Li-Ion Anodes with High Areal Capacity

Abstract:
Highly porous, conductive Si-CNT sponge-like structures with a large areal mass loading are demonstrated as effective Li-ion battery anode materials. Nano-pore formation and growth in the Si shell has been identified as the primary failure mode of the Si-CNT sponge anode, and the formation of such nanopores can be minimized by tuning the cutoff voltages. In conjunction with experiments, a theoretical analysis was carried out to explain the pore formation mechanism. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
