Final Report Summary - HI-C (Novel in situ and in operando techniques for characterization of interfaces in electrochemical storage systems)

Executive Summary:
Batteries and super-capacitors are highly important elements in the development of a society based increasingly on sustainable energy. Both are complex electrochemical systems trans-porting various species through materials and across interfaces. Interface properties and dynamics are governing e.g. ionic and electronic transport, reactivity/degradation, stability, kinetic barriers and phase mobility. In the Hi-C project, new and improved techniques for in situ charac-terization on the nanoscale have been developed. These are combined with advanced modeling and computational methods to obtain a detailed understanding of electrochemical processes at an atomic and molecular level.
The fundamental knowledge obtained was used to optimize new and existing electrode materials and SEI (Solid Electrolyte Interface) formation for lithium ion batteries and supercapacitors.
The Hi-C consortium possesses together a wide variety of competences within materials synthe-sis/fabrication, advanced characterization and computational techniques. Bio-Logic Science Instruments Ltd (former Uniscan Instruments Ltd) has in the Hi-C project developed a scanning elec-trochemical microscopy cell for in situ characteri-zation of interface reactions in battery cells. VARTA Microbattery GmbH is one of the signifi¬cant battery and supercapacitor manufacturers in Europe. Haldor Topsøe A/S is a major producer of catalysts, but is expanding also into battery mate-rials.
