Electrode cutting is a significant process step in the production of lithium ion batteries. Different cutting technologies exist to singularize electrode sheets out of electrode coils e.g. mechanical and laser cutting. The laser cutting process combines the conventional notching of the current collector and cutting out electrode sheets. This process provides a high cutting flexibility […]

The formation of Lithium ion batteries (LIBs) is one of the most important steps during battery production, which can affect the batteries lifetime, safety and quality. The initial charge/discharge cycles determine the structure and composition of the solid electrolyte interphase (SEI) and controls a time-consuming production step. Numerous studies focused on the understanding of the […]

Lithium-ion batteries are considered to be one of the most important technologies to enable a successful transition to renewable energies. Ni-rich layer oxides, with at least 80% nickel, are particularly interesting as the cathode active material (CAM) for electric vehicle applications due to their high specific capacity of around 200 mAh/g and high average potential […]

The overwhelming majority of lithium-ion batteries currently in use feature a graphite anode, which is approaching its maximum theoretical capacity. Lithium metal batteries are regarded as pivotal enablers for the forthcoming generation of lithium-ion technology, largely due to their superior energy density. Indeed, lithium (Li) metal has the lowest reduction potential (-3.04 V vs. std […]

Lithium metal batteries (LMBs) offer high theoretical capacity (3860 mAh·g⁻¹) and a low electrode potential (-3.04 V vs. SHE). However, challenges such as inhomogeneous solid electrolyte interface (SEI) formation and high surface area lithium (HSAL) growth lead to low Coulombic efficiency, rapid capacity decay, and safety concerns. To address these issues, localized high-concentration electrolytes (LHCEs) […]

To assure optimal operations of the traction battery at all times and further provide reliable prediction of the remaining range, the exact determination of the state of charge (SoC) is key. The increased incorporation of cells with lithium iron phosphate (LFP) cathodes poses critical challenges for conventional SoC estimation within the battery management unit (BMU) […]

Performance and lifetime testing of batteries requires considerable effort and expensive specialist equipment. A wide range of potentiostats and battery testers are available on the market, but there is no standardization of data exchange and data storage between them. To address this, we present Galv, a battery test database developed to manage the growing challenges […]
