New environmentally benign iron based cathode materials, tin and/or silicon anode materials, and ionic liquid electrolytes will be developed for a power optimised 200 Wh/kg Li-ion battery to be used within 5 years. The same electrode materials will also be temperature tested together with new polymer and ionic liquid electrolytes operating at temperatures between 60-150ºC in a 250 Wh/kg Li-ion battery to be used in hybridized vehicles. The long term goal is to use the ionic liquid electrolytes and the tin and/or silicon anodes to construct metal-air (e.g. lithium) batteries with capacities >600 Wh/kg that can be used 15 years from now. These ambitious goals require a broad and fundamental knowledge about material synthesis and characterisation as well as of theoretical modelling. Given the complexity of the Li-ion battery, the proposed battery concepts are necessary for a continued development of new battery materials. By combining the expertise on synthesis, characterization and full scale cell testing of nano- and bulk electrode materials at Uppsala University, the deep knowledge of polymer electrolytes, electrolyte salts and ionic liquids at Chalmers, and the modelling expertise at KTH, we are able to present a full-scale project covering all aspects of materials for Li-ion batteries. An industrial reference group (with representatives from Höganäs AB, Scania CV AB, AB Volvo, ABB, Husqvarna AB, LiFeSiZE AB, LUTAB, ETC AB) will also be linked to the project.
