| Atomic Scale Insight into the Structure, Charge Transport and Electrochemical Properties of Olivine Phosphate Solid Solutions | Major | 2023 | The proposed research will ensure the synthesis of m-NFP and doped m-NFP mesostructured and non- toxic cathode material by modified solid state route. Judicious execution of this project, we will be able to show that the m-NFP has potential to deliver highly efficient mesostructured cathode for sodium ion batteries with high energy density. The chosen cathode material is expected to display tunable physical properties over an unusually broad range through the manipulation of the geometric and chemical characteristics of the nanostructures and the tethered networks. In addition, the present system is likely to display superior electrochemical properties, i.e. better than the other commercially used cathode material with wide electrochemical stability window. It is also predicted that from the proposed work, the factors that affect electrochemical properties based on the electronic structure, which strongly depends on the crystallite size. The electronic properties of cathode material are mainly determined by the various kinds of defect states present in the system in addition to the intrinsic crystal structure. The charge transport mechanism in the present system will be understood by undertaking frequency and temperature dependent electrical conductivity measurements. Further, detailed electrochemical characterization will be performed for its applicability in commercial application. It is believed that on the basis of obtained results, we would be able secure alternative cathode material for the currently used unsafe cathode material in sodium ion batteries. Based on the electrical and electrochemical properties of mesostructured m-NFP and doped m-NFP, we will be able to develop coin cell batteries. In addition, the proposed combined theoretical and theoretical work on advanced cathode material would lead to better understanding electronic structure and high impact journal publications/patent. | Ongoing since 01-06-2023 (1 years, 7 months, 27 days) | ||
