Using acoustic emission (AE) measurements enables to indirectly obtain information about degradation processes within a material. By placing a piezoelectric sensor outside a battery test cell, acoustic waves emitted from irreversible process within can be converted into a measurable voltage signal. These processes can be e. g., gas evolution or crack formation. The AE technique […]

Due to the rapidly increasing demand for lithium-ion batteries (LIB) it is crucial to lower the need of production energy per kWh of battery capacity produced. One of the most energy consuming process steps is the drying of wet-coated electrodes. Eliminating this step offers a high potential to improve carbon footprint and sustainability as well […]

This study aims to systematically examine aging mechanisms of lithium-ion cells. For this purpose, three different commercially available cylindrical cells featuring nickel-rich cathodes and graphite-based anodes are tested. Each cell type undergoes five different aging methods, encompassing calendar aging, cyclic aging, and a realistic drive cycle profile. Differential voltage analysis is employed as a non-destructive […]

Traditional lithium-ion battery state monitoring primarily relies on external measurements of current, voltage, and temperature conducted outside the individual cell and inside the battery module. Given that temperature variations such as gradients can significantly impact battery performance, ageing and pose challenges for conventional evaluation methods, localized temperature sensing presents an innovative approach to gain insights […]

A successful transformation of the automotive industry requires education/qualification of employees along the value chain. The B³ Batterie-Bildungsnetzwerk Bayern, as a “Battery Competence Trio” will make a substantial contribution through tailormade qualification concepts for employees of small and medium-sized companies (SMEs) throughout Bavaria. In B3, the consortium will develop these qualification concepts along the battery […]

The increasing demand for batteries is mainly driven by the electrification of transport. In this context, achieving high gravimetric and volumetric energy densities (ED) in batteries is particularly important. The use of solid-state batteries (SSBs) offers several advantages, such as improved ED, higher operational safety, extended shelf life, and higher C-rates. In addition, the use […]

Lithium ion batteries (LIBs) have become omnipresent in our society. The growing demand for them has led to increasing interest in more environmentally friendly ways of production. Today, the dominant process for the manufacturing of electrodes for LIBs is the solvent-based casting process. This process, however, comes with several drawbacks. The most common employed solvent […]
