Tetragonal gallium phosphide monolayer: A promising anode material for sodium-ion batteries

We are happy to announce that Assoc. Prof. Dr. Nguyen Xuan Sang and colleagues recently published their work entitled “Tetragonal gallium phosphide monolayer: A promising anode material for sodium-ion batteries” in the Materials Today Physics (Elsevier) 

Abstract:

In this study, we systematically investigate the crystal structure, electronic properties, and mechanical behavior of the tetragonal GaP monolayer. Furthermore, we examine the adsorption characteristics of Na atoms on the GaP monolayer and evaluate its practical viability as an anode material for sodium-ion batteries. Our findings reveal that the tetragonal GaP monolayer exhibits metallic characteristics and possesses remarkable mechanical flexibility. Notably, it demonstrates anisotropic mechanical responses and a low Na-ion diffusion energy barrier of 0.23 eV. Additionally, the GaP monolayer shows a high theoretical storage capacity of 798.46 mAh/g along with a moderate working voltage, making it a promising candidate for Na-ion battery applications.
