▎ 摘 要
We demonstrate a new nanohybrid anode made up of graphene supported mesoporous single crystal Si (MSC-Si/G) on Cu foam by a facile method. Such intriguing nanohybrids are not only highly stable anode materials for LIBs with a high reversible capacity of 1703 mA h g(-1) at 200 mA g(-1) as well as rapid charge and discharge capability (390 mA h g(-1) at 5000 mA g(-1)), but also show no obvious capacity fade after 160 cycles at 200 mA g(-1) or over 130 cycles at 5000 mA g(-1).
