Abstract
⺠Na1.8FePO4F/C composite material is prepared by a new mechanical-ceramic method. ⺠The local structure of NaxFePO4F electrodes were examined for the first time by XAS. ⺠The local changes from Na1.8FePO4F to NaFePO4F, and then to Na2FePO4F are small. ⺠Both Fe2+ and Fe3+ are in high spin configurations in NaxFePO4F electrodes. ⺠Capacity and capacity retention are improved by using NaPF6 electrolyte in EC:DEC.
