As lithium-ion batteries age, the state-of-health (SOH) of the batteries reduces, which implies that the capacity that can be stored reduces, and simultaneously, the internal resistance increases. Before such batteries are discarded for recycling or used for a second life, the estimation of the SOH becomes very important. In this work, we investigated the applicability […]

The development of reproducible process chains for cathode sheets of solid-state batteries (SSB) is a key challenge in the further development of SSB. Contact losses between active material particles and solid electrolyte particles, high porosities and degradation processes of the solid electrolyte lead to a decrease in electrochemical performance and to faster ageing of the […]

Self-heating ignition is an important form of failure when lithium-ion batteries are not in use, such as when stored or transported. Despite being widely studied, existing studies have only focused on fresh batteries. However, it is of more practical use to understand self-heating ignition for degraded cells, regardless of how they are used. In this […]

1. Introduction Acetonitrile (AcN) is a promising organic solvent for lithium-ion battery (LIB) electrolytes from the viewpoint of fast-charging and extremely low temperature performance due to its low viscosity and high relative dielectric constant. Asahi Kasei succeeded in developing an AcN-containing electrolyte for LIBs by deriving the appropriate combination of additives that suppress the reduction […]

The economic viability of energy storage systems is essential for their adoption in commercial and industrial sectors. This poster presents findings on the profitability of peak shaving and self-consumption optimization, analyzed both individually and in combination using simulations based on real load data from 50 small- and medium-sized companies in Germany. A key innovation of […]

In view of the worldwide efforts to reduce global CO2-emissions, EVs are seen as a climate-friendly alternative to fossil-based propulsion methods. Therefore, the overall share of EVs is expected to rise even more in the nearer future. This very technology however, not only offers advantages and possibilities, but also poses a great danger int the […]

Continuum-scale battery models, such as the Doyle-Fuller-Newman model, rely on the volume averaging of the underlying microscale differential equations in order to obtain a macroscale model. However, experimental characterizations of commercial electrodes show that active material particles are not necessarily microscopic in relation to electrode thickness. In this contribution, we introduce the concept of optimal […]

Sodium-ion batteries (SIBs) are considered a more sustainable, resource saving, and cost-effective alternative to lithium-ion batteries (LIBs) as they can be designed without using critical or scarce raw materials and compounds such as cobalt, copper, lithium or graphite [1,2]. These advantages on the material level, along with the ability of using existing manufacturing equipment, have […]
