- Abstract
Cobalt–tin intermetallic compounds with different particle size have been obtained and characterized by using 119Sn Mössbauer spectroscopy as a main tool. The electrochemical behavior of the Co–Sn compounds has been evaluated in lithium test cells. The Lamb–Mössbauer factors for CoSn with different crystallite sizes have been calculated. The results f nano − CoSn(300 K) = 0.19 and f coarse − CoSn(300 K) = 0.55 are obtained. Nano-CoSn exhibits larger capacity to react with lithium than coarse-CoSn.
