Novel anodes for rechargeable lithium batteries


Research objectives and content
The focus of this application is on novel oxide anodes for lithium batteries, 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. Various complex oxides, eg spinel MgSn204, ramsdellite Li2MgSnO8, which should tolerate a larger degree of Li-insertion will be investigated. Tin phosphates will also be synthesised and phase equilibrium relations in the Sn:P:B:O system investigated. Glassy systems in the lithia: phosphate: borate system will be targeted and the extent of SnO2 solubility in these systems investigated. PbO, Bi203 and Sb203 offer similar behaviour to SnOx, as do some transition metal oxide spinel systems. These will be investigated and attempts made to optimise potential and capacity by control of composition and nanostructure.
Training content (objective, benefit and expected impact)
The candidate already has an excellent background in applied electrochemistry, this project will allow him to develop his expertise in solid state chemistry and solid state electrochemistry. On completion of the Fellowship the candidate will have an excellent curriculum in these technologically important areas. This will not only greatly enhance his career prospects it will also be of benefit to the European economy. Links with industry / industrial relevance (22)
The research group has strong links with companies involved in Lithium battery manufacture in Europe and with companies actively considering inward investment to set up a manufacturing capability in Europe.
