Cycling behavior of nanophase Cu/sub 6/Sn/sub 5/ anodes

摘要

Alloy anodes offer the advantages of higher capacity and enhanced safety compared to graphite. One alloy that has received attention is Cu/sub 6/Sn/sub 5/. A major problem with Cu/sub 6/Sn/sub 5/ and alloys in general is their poor capacity retention upon cycling. It was observed that a nanophase Cu/sub 6/Sn/sub 5/ alloy produced by a chemical method has increased cycle life compared to Cu/sub 6/Sn/sub 5/ alloys produced by conventional melting and mechanical alloy.
