Abstract :
Alloy anodes offer the advantages of higher capacity and enhanced safety compared to graphite. One alloy that has received attention is Cu 6Sn5. A major problem with Cu6Sn5 and alloys in general is their poor capacity retention upon cycling. It was observed that a nanophase Cu6Sn5 alloy produced by a chemical method has increased cycle life compared to Cu6Sn5 alloys produced by conventional melting and mechanical alloy
