With the decentralization of renewable energy sources, multi-energy systems (MES) integrating the electrical sector with mobility or thermal sectors are increasingly preferred for their sustainability and flexibility. However, optimizing such complex systems is challenging, requiring a balance of profitability, asset aging reduction, and sustainability. This study examines a real-life MES setup for residential buildings housing […]

A database of test vectors with simulated real-world driving was created within a pre-competitive working group, supported by Consortium for Battery Innovation (CBI). Its purpose is the validation of algorithms for performance prediction of the 12V PbA battery in vehicles for safety-relevant profiles (Safety State-of-Function, SSoF). Here, a small subset was analyzed for parameter changes […]

Water and hydrofluoric acid cause the electrolyte to decompose, and as the water content in the electrolyte increases, the SEI layer becomes thicker and rich in lithium carbonate. This affects the battery with increased battery resistance, safety problems and loss of capacity. Therefore, limit values of 20 ppm for water and 50 ppm for HF […]

The economic viability of vanadium flow batteries (VFBs) depends on maintaining optimal power output and energy capacity throughout their lifespan. A key factor in achieving this is the precise monitoring of the electrolyte-specific state of charge (SoC). This work presents a novel open-circuit-potential (OCP) cell designed for real-time, cost-effective, and reliable SoC monitoring in VFBs. […]

The quick characterization of materials plays an important role in both the development of new compounds as well as in quality control purposes. Therefore, it can be critical to be able to evaluate materials on the base level way before they have even been electrochemically tested. Electrical conductivity is the most obvious property that needs […]

Lithium plating is a safety and performance concern in lithium-ion cells. This study investigates the effects of temperature and charging current rate on lithium plating, aiming to develop an index to assess a cell’s susceptibility to plating. A quick electrical test was designed to induce lithium plating under varying conditions. For this, a constant temperature […]
