Mechanochemical synthesis and electrochemical properties of nanostructured electrode materials for Li ion batteries RID A-5377-2011 / Mulas, Gabriele Raimondo Celestino Ettore; Enzo, Stefano; Arca, E; Gerbaldi, C; Penazzi, N; Bodoardo, S; Hassoun, J; Panero, S.; BONATTO MINELLA, C. - In: JOURNAL OF SOLID STATE ELECTROCHEMISTRY. - ISSN 1432-8488. - 13:2(2009), pp. 239-243.

Abstract:
We focus on the synthesis by ball milling and on
the electrochemical characterization of nanocrystalline
bimetallic and composite materials to be employed as
anodes in Li ion batteries. Ni3Sn4 and Ni3Sn2 based
compounds were obtained by ball milling of three different
Ni–Sn mixtures. The properties of the resulting anodes for
Li ion batteries were evaluated as a function of composition.
Moreover, a biphasic system is presented, with CoSn2
and CoSn type structures, arising from the synthesis of the
Sn31Co28C41 composition. When cycled in a Li cell, this
material showed a high reversible specific capacity, about
450 mA h g−1, and a very good electrochemical and
structural stability, making it of interest for application
purposes.
