![عکس صفحه اول مقاله: Low temperature synthesis and characterization of nanoscale Cu6Sn5 particles as lithium anode material Low temperature synthesis and characterization of nanoscale Cu6Sn5 particles as lithium anode material](/preview/png/1292438.png)
The current article displays the possibilities of borohydride reduction method, carried out at room temperature and ambient atmospheric condition, to be a technological process for large scale production of Cu6Sn5 nanoparticles. This composition is very attractive recently via anode material in secondary lithium batteries. The content changes of prepared nanoparticles depend on the initial ratio of metal salt solutions and the concentration of complex forming agent used. One hypothesis is draw out on the basis of experimentally analyzed content of electrodes, interrupted at various potentials of the first charge cycle: 690 mV, 540 mV, 200 mV and 10 mV. Thus, the good life cycle of these nanoscale systems is a result of an intercalation of lithium occurring during phase transition from hcp to fcc of the lattice.
