Binary to quaternary Mo-based phosphate glasses cathodes Li-batteries: Influence of Mo substitution by Fe and Mn
Year: 2024
Type: article
Abstract: To correlate glass chemical compositions with electrochemical performances, seven Mo-phosphate glasses (with/without Fe and/or Mn) were prepared using a Design of Experiment approach and characterized (XRD, EDS, XRF). Evaluated as cathode active materials in Li-metal coin cells, their electrochemical performances were measured by galvanostatic cycling at C/50 rate. The glasses show high first discharge capacities, but energy densities (420 to 705 Wh/kg at the material level) were limited by low voltage. Significant capacities losses (≈50%) occured between the first and second discharges, affecting subsequent performances. Ternary diagrams for first cycles discharge capacities and voltage are presented.
