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-Mn₃O ₄ powders with a molar ratio of 1:1 of the Zn and Mn components are shown to have high capacities and good cycling performances. Powdered eggs: A spray-pyrolysis process is introduced as an effective tool for the preparation of yolk-shell-structured materials. Yolk-shell-structured ZnO-Mn ₃O₄ powders with various molar ratios of Zn and Mn were prepared (see figure), and a 1:1 ratio is shown to have the high capacities and good cycling performances that are needed for anode materials in Li-ion batteries.
