Abstract

A spray-pyrolysis process is introduced as an effective tool for the preparation of yolk–shell-structured materials with electrochemical properties suitable for anode materials in Li-ion batteries (LIBs). Yolk–shell-structured ZnO–Mn3O4 systems with various molar ratios of the Zn and Mn components are prepared. The yolk–shell-structured ZnO–Mn3O4 powders with a molar ratio of 1:1 of the Zn and Mn components are shown to have high capacities and good cycling performances.
