Exploring the structure of a highly defective fluoride ion conductor, b-KSb1-dF4-3d
Abstract: As the global demand for energy increases, the need for safe, efficient and low-cost energy storage grows. At present, Li-ion batteries dominate the rechargeable battery market but there are concerns around the abundance, cost and safety of the raw materials which means that the demand for new technologies is enormous. Fluoride ion shuttle batteries (FIBs) have the potential to offer increased capacity using earth-abundant materials but current technology has the significant disadvantage of needing to operate at high temperatures to achieve sufficiently high conductivity in the solid electrolyte. The search for room temperature fluoride ion conductors led recently to the discovery of a highly defective derivative of potassium tetrafluoroantimonate, KSbF4. The defective material exhibited greatly enhanced fluoride-ion conductivity, hovever the crystal structure appeared to have changed little, if at all (at least as observed by X-ray powder diffraction). This proposal is concerned with using neutron total scattering and reverse Monte Carlo analysis to explore the local and average structures of the stoichiometric and defective materials and determine the structural origin of the enhanced fluoride ion mobility.
