Novel Core‐Shell Sn‐Cu Anodes for Lithium Rechargeable Batteries Prepared by a Redox‐Transmetalation Reaction

Core-shell type nanoalloys in which the Cu atoms uniformly reside as a shell around a core of Sn nanoparticles are achieved by reacting Cu(acac)2 with tin nanoparticles. The core-shell Sn@Cu nanoparticles further demonstrate significantly improved rate capability at higher C rates than Sn@C nanoparticles.
