- Abstract
This article deals with the study of the electrochemical performances and the lithium insertion-deinsertion mechanism by mean of 119Sn Mössbauer spectroscopy of NbSn2. The first discharge shows a plateau at 0.05 V vs. Li + /Li0 corresponding to a displacement reaction with the formation of Li7Sn2. A specific capacity of 487 mAh/g can be reached during this first discharge.
