Unraveling the lithium loss mechanisms during the high-temperature solid-state synthesis of ternary lithium-ion cathode materials

Q: What does this research mean for the field?

Lithium loss during high-temperature solid-state synthesis of NMC cathodes is primarily driven by substrate reactions rather than Li2O evaporation, with moisture providing a secondary loss pathway via LiOH(g) formation.

Key Points

The study aims to identify the mechanisms responsible for lithium loss during the synthesis of NMC cathodes.
Investigated lithium loss mechanisms during high-temperature solid-state synthesis.
Analyzed the impact of substrate reactions and moisture in the calcination atmosphere.
Lithium loss is primarily caused by substrate reactions, not by Li2O evaporation.
Moisture in the calcination atmosphere leads to additional lithium loss through LiOH formation.

Abstract

Lithium loss during NMC cathode synthesis is dominated by substrate reactions, not Li 2 O evaporation. Moisture in the calcination atmosphere provides a secondary loss pathway via LiOH (g) formation.
