SCCER Heat and Electricity Storage
In order to bring the technology forward, three fundamental research directions will be pursued with strong synergies between them, accompanied by two applied projects. Improvement of Li-ion technology towards higher power density by development of novel cathode and anode materials for lithium-ion batteriesvia nano-structuring, to increase the energy density of current lithium-ion cells by 50 %.. 100 %. An other way to increase the power densityis to increase the cell potential. This requires new materials with long term stability at increased potentials. Computational prediction based on the density function theory (DFT) will guide the experimental efforts. Cost Reduction by going beyond lithium-ion technologies: Highly exploratory research will target novel electrode materials which operate viastorage of other than lithium ions, such as sodium (Na+). This substitution of lithium ions for sodium ions, which have a higher availability andthus allow cost reduction, is one of the mid-term goals. It is targeted to achieve performance data equal to the current state of the art of lithium iontechnology.Development of manufacturing technology is a task that aims at planning, refining and realization of a pilot production line for lithium- (and sodium)ion batteries in small series. This is required to qualify new material in full cells based on reproducible assembled cells. Performance, lifetime, safety and reliability of battery systems is addressed by qualification and verification of procedures to estimate reliability and lifetime. Further, the compliance with safety regulations of electricity storage systems with batteries will be established. The Competencies of the Team are theoretical prediction of physical / chemical behavior of electrode materials, material synthesis and electrochemical characterization on lap- and application-scale, as well as analysis and optimization of production processes.
