Battery storage systems are becoming increasingly important for industrial companies – driven by rising energy costs, the desire for self-sufficiency and lower investment costs for storage systems. Their versatility makes storage systems profitable: In addition to peak load capping, which reduces your own electricity costs, they can provide balancing energy or exploit the volatility of […]

The performance of present generation Li-ion batteries is not sufficient to completely electrify the car fleet. This disruptive step requires new ways to identify the best materials combinations in the battery cell. Simulations can contribute estimates of the density and ion conductivity for arbitrary electrolyte formulations [1] as well as the open cell voltage (OCV) […]

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) […]
