Title: Suppressing the Voltage Decay of Low-Cost P2-Type Iron Based Cathode Materials for Sodium-ion Batteries

Abstract

Rechargeable sodium-ion batteries with earth abundant Fe/Mn based cathodes are promising choice for grid-scale applications. However, the important candidate, P2-type Fe based materials suffer from server voltage decay during battery operation, which is due to the Fe 3+ migration to the neighboring tetrahedral sites. Two Fe based layered oxides Na 0.7[Cu 0.15Fe 0.3Mn 0.55]O 2 and Na 0.7[Cu 0.2Fe 0.2Mn 0.6]O 2 have been prepared. With the combination of in-situ XRD, X-ray PDF, hard and soft X-ray absorption, we demonstrate that the voltage decay in Fe based layered oxides comes from a dynamic origin. Dramatic phase transition can be triggered by higher upper voltage limit and partially irreversible Fe migration lead to voltage fade. With excess Cu doping into crystal lattice, Fe migration can be much mitigated and structural stability can therefore be maintained. Furthermore, Cu introduction brings about extra capacity via the correlation between transition metals elements and ligand oxygen, which may well compensate capacity loss from inert impurity doping. Finally, possible strategies for suppressing the detrimental voltage decay in battery cathodes can be proposed accordingly.
