Abstract:
This thesis presents the work carried out on two types of nano-particle materials with the purpose of investigating their lithium ion storage properties. Several different types of morphologies of tin disul�de were grown hydrothermally, including several known and two novel morphologies. These have been extensively characterised using both electron microscopy and computational simulation, which led to a good understanding of the topology of the particles. In a further step, these were tested electrochemically in lithium ion test cells to elucidate their lithium ion storage properties. While it was possible to reversibly store a significant amount of lithium, the cells unfortunately could not yet compete with other available lithium ion cells. In addition, a hybrid material composed of lithium niobate and lithiated niobium sulfide was also investigated. For this, a lithium niobate precursor was created using either a hydrothermal synthesis or commercially available material. The synthesis route was shown to be able to produce lithium niobate, but unfortunately still contained other niobium oxide contaminants. Both were sul�dised using a novel approach and shown to exhibit layered shell growth as would be expected for lithiated niobium sulfide. Initial test cells were constructed and tested, but solid electrochemical results could not be gathered before the end of the project.
