Abstract Many industry sectors are currently experiencing a strong demand for electrification. This applies to the automotive industry, which aims for production of hybrid and full electric vehicles to reduce carbon dioxide emissions and proceed to environmentally compatible transportation. Electrification calls for a range of system components, that need to be developed and tested. On […]


Lithium-ion batteries are well established as energy storage devices for a wide range of mobile applications from cell phones through power tools to electric vehicles. The different types of usage lead to distinct requirements concerning the battery system, resulting in customized dimensioning of the single components. For the sustainable, technically and economically efficient battery production […]


The upcoming transformation from internal combustion vehicles to electric vehicles in the private transport sector, together with the increasing demand for electricity, leads to challenges such as over-loading for the power grid. This study shows a technical and economic analysis to what extent storage systems can be an alternative to conventional grid reinforcement. The objective […]


The general interest in the implementation of renewable energies, particularly in the development of lithium-ion batteries, makes lithium a key element to be analyzed. We are working to develop a tool to determine if the isotopic effect of lithium has an impact on battery aging. For this purpose, we propose an analytical procedure for isotope […]


Energy storage materials are a topic of continued interest, particularly with regards to elucidating structure-property relationships. This includes not only exploratory work in terms of mapping complex ternary or quaternary phase diagrams but understanding material performance in assembled test cells and devices. X-ray diffraction (XRD) is one of the key analytical techniques used in these […]


Energy renewable resources can be stored in various ways. Considering electrochemical storage, Li-based batteries offer high energy densities combined with a high degree of design flexibility. In particular, batteries using Li+ as an ionic charge cariier are an emerging option to power electric vehicles. Such batteries may, however, suffer from flammable liquid electrolytes conventionally used […]


Due to the push of powertrain electrification for road transport decarbonisation purposes, an increase in demand for respective traction batteries is projected in the upcoming years. By today’s measures the battery contributes a large part to the CO2 emissions of the vehicle in the life-cycle. A consequent monitoring and reduction of these CO2 outputs are […]


Li4Ti5O12 (LTO) is considered the anode material of choice for low-cost, high-power lithium-ion batteries.[1] Advantageously, just as in the case of graphite-based electrodes, also LTO electrodes can be prepared using water-soluble, fluorine-free polymers as binder and water as the processing solvent, rendering the fabrication sustainable and cost-efficient.[2] Recently, we optimized the aqueous processing of lithium […]


Abstract Understanding degradation is critical to unlock the true potential of lithium-ion batteries. Poorly understood degradation leads to reduced energy/power density through over-engineering, and increased safety risks and failure rates. Thermal management is key to minimizing battery degradation. Yet, previous experimental results have shown the effect of different thermal management strategies on degradation is still […]
