Summary on Grant Application Form |
|
The focus of this application is on novel oxide anodes, which have recently been demonstrated to exhibit very large capacities. The work will involve both main group, especially tin, and transition metal oxides, paying particular attention to microstructure, nanostructure and the formation of amorphous structures. In particular, it is proposed to carefully study the mechanism of lithium insertion and to ascertain if the process involves naked metal in an oxide composite, or if it involves some sort of suboxide species. Solid state NMR (Li,Sn), EXAFS and Sn Mossbauer will be widely utilised during the project to investigate both co-ordination and electrical properties (i.e. electronic and ionic mobility).Various complex oxides, e.g. spinel MgSn204, ramsdellite Li2MgSn08, which should tolerate a larger degree of Li-insertion will be investigated. Tin phosphates will also be synthesised and phase equilibrium relations in the Li-insertion will be investigated. Glassy systems in the lithia:phosphate: borate system will be targeted and the extent of Sn02 solubility in these systems investigated. PbO, Bi203 and Sb203 offer similar behavior to SnOx, as do some transition metal oxide spinel systems. these will be investigated and attempts made to optimize potential and capacity by control of composition and nanostructure.
