Our research group deals with the development of 4th generation Li-ion batteries (solid state batteries and Li-ion batteries with conversion-type cathodes, such as Li-S batteries) and post Li-ion (Na-ion) battery functional components. Moreover, we investigate the complex electro-chemo-mechanical ageing processes of these battery systems. We develop and investigate new-generation solid state Li-ion conductive electrolytes/composite electrolytes, and electrode active compounds. Our ultimate goal is to manufacture prototype battery cells with high energy (>400 Wh/kg) and tuneable power density performance with excellent safety attributes (non-flammable, no thermal runaway) for future mobile applications.
