Probing how Ti- and Nb-substitution affect the stability and improve the electrochemical performance of β- and ε-LiVOPO₄

Abstract

LiVOPO4 is a promising next-generation multi-electron cathode material, boasting a theoretical capacity of 305 mAh/g, significantly higher than any commercially used Li-ion battery cathode material. However, the material still faces...

Exploring the unexpected electrochemical dynamics of lithium vanadyl phosphate electrodes in zinc battery systems

“…Furthermore, following the discharge reaction, the electrode exhibited peak splitting, indicating a deviation from the Oh symmetry. 56 The symmetry was recovered after the charging reaction, indicating the electrochemical reversibility of the β-LiVOPO 4 cathode in the zinc cell.…”
