Maricite NaFePO₄/C/graphene: a novel hybrid cathode for sodium-ion batteries

For the first time we have produced maricite NaFePO4nanoparticle entwined graphene sheets capable of delivering an outstanding capacity of 142 mA h g-1after 300 cycles, corresponding to ∼98% capacity retention. This work emphasizes the importance of exploring the new structure and provides a method for the development of graphene-based cathodes.
