Schmidt Naturally Rolled-Up C/Si/C Trilayer Nanomembranes as Stable Anodes for Lithium-Ion Batteries with Remarkable Cycling Performance Angewandte Chemie International Edition 52
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.
