摘要: The nature of the chemical bonding in an amorphous Si-coated carbon nanotube (Si-CNT) anode, and its evolution upon electrochemical cycling, have been investigated using comprehensive X-ray absorption spectroscopy (XANES) at Si L- K-edges, along with C O K-edges. nanolayer on CNT is found to be anchored via Si–O–C bonding. This bond weakens accompanied by generation Li2CO3 surface Si-CNT. These findings are crucial designing further improved Si–C composite anodes for lithium ion batteries.
