Abstract
The use of amorphous carbon-coated tin particles as an alternative material to ensure the dimensional integrity during Sn alloy/dealloy was highlighted. Inductively coupled plasma mass spectroscopy (ICP_MS) analysis of the Sn in the coated carbon showed that Sn wt% was 80, and the remaining 20 wt% was estimated to be carbon. It was indicated that most hydroxyl groups in glucose were removed during the hydrothermal reaction. It was found that an almost uniform amorphous carbon coating on the tin nanoparticles was prepared from aqueous glucose solutions using a hydrothermal method at 180°C, which facilitated enhanced dimensional stability during Li alloying/dealloying.
