Electrochemical performances of vitreous materials in the system Li2O–V2O5–P2O5 as electrode for lithium batteries

Glass composition 25Li2O–50V2O5–25P2O5 has been investigated as a potential material for electrode. Electrical properties as well as electrochemical performances of this glass composition have been characterized and results show a capacity less than 80 mAh g− 1 when tested in the [3–4.5 V] potential window. To the best of our knowledge, this is the first lithiated amorphous material reported as a potential positive electrode material. Glasses, due to their wide available compositions in a given system and their easy processing, pave the way to new type of electrode material.

► Electrochemical performance of glass in the system Li2O–V2O5–P2O5 is reported.
► Capacity of 80 mAh g− 1 is obtained in the [3–4.5 V] range.
► Amorphous structure of glass remains upon cycling.
