摘要：

Rolling their own: Naturally rolled-up C/Si/C trilayer nanomembranes (see scheme) exhibit a high reversible capacity of about 2000 mAh g-1 at 50 mA g-1, and 100 % capacity retention at 500 mA g-1 after 300 cycles. This technique is general and could be applied to the fabrication of other battery materials that undergo large volume changes. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
