Transition metal oxides (TMOs, TM = Ni, Cu, Ti, Fe, etc.) have attractive features as high performance anode materials for the next generation of Lithium-Ion Batteries (LiBs), as well as promising prospects to be implemented also in rapidly expanding Sodium-Ion Batteries (NiBs), due to their higher lithium/sodium storage capabilities, enhanced safety and low cost if compared to commercial graphitic anodes.

Abstract

Transition metal oxides (TMOs, TM = Ni, Cu, Ti, Fe, etc.) have attractive features as high performance anode materials for the next generation of Lithium-Ion Batteries (LiBs), as well as promising prospects to be implemented also in rapidly expanding Sodium-Ion Batteries (NiBs), due to their higher lithium/sodium storage capabilities, enhanced safety and low cost if compared to commercial graphitic anodes. Nevertheless, their large volume expansion/contraction during Li+/Na+ ion insertion/extraction leads to the rapid destruction of the electrode and loss of inter particle contact, which often results in a strong irreversible capacity loss and poor cycling stability. As a result, their practical application is limited so far. Synthesis of TMO in various nanostructured forms represents an appealing solution. In addition, coupling the positive characteristics of nanostructured TMOs with graphene sheets (GNS) leads to enhanced material stability and greatly improved electrochemical performances. In this work, we summarize our recent results on the structural/morphological characteristics and electrochemical behavior in Li/Na-based batteries of nanostructured TMOs and hybrid 3D/2D TMO/GNS composite microspheres obtained by fast spray-drying as well as TiO2 nanotubes obtained by anodic oxidation.
