Facile synthesis of cerium oxide nanostructures for rechargeable lithium battery electrode materials

Abstract

A facile method is developed to synthesize cerium oxides with plate and brick morphologies by the thermal decomposition of nanostructured oxalate precursors. The electrochemical test of the Li-ion battery reveals that the as-synthesized CeO₂ nanostructures affect their electrochemical properties. Especially, the specific capacity of the brick-like CeO₂ nanostructured electrode is above 460 mA h g⁻¹, with good stability up to 100 charge–discharge cycles.
