One-pot galvanic formation of ultrathin-shell Sn/CoOx nanohollows as high performance anode materials in lithium ion batteries

The thermolysis of a heterobimetallic Sn-Co organometallic precursor resulted in the formation of hollow Sn/CoOx nanomaterials through galvanic reaction between metal species. The Sn/CoOx nanohollows with 6.1 nm diameter and similar to 1.5 nm shell thickness showed excellent lithium storage capacity of up to 857 mA h g(-1) after 30 cycles.
