Morphological study of SnSb/Graphite composites influenced by different ratio of Sn:Sb

Experimental studies have shown that Sn/graphite nanocomposites are promising anodes for next generation rechargeable Li-ion batteries, as the graphite limits the volume expansions that Sn experiences upon Li-insertion. In order to provide further mechanical stability to the Sn a fabrication methods...
