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.
