Abstract

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