Simple fabrication and electrochemical performance of porous and double-shelled macroporous CuO nanomaterials with a thin carbon layer

Abstract

In this work, different types of CuO particles with a thin carbon layer were fabricated and tested as anode materials for lithium ion batteries. The pH-responsive hydrogel microspheres are utilized as a template for morphological and structural changes of composite particles. The structure of CuO particles and a thin carbon layer have the effect to improve the electrochemical performances of the lithium ion cells.
