From Black Mass to Cathode Material: How Inline Concentration Measurement Makes CAM Production More Efficient
Electromobility is growing rapidly—and with it, the demand for high-performance lithium-ion batteries. To reduce dependence on Asian supply chains, Europe is currently investing heavily in establishing its own battery value chain. New production facilities for cathode active materials (CAM) are being built in countries including Germany, Finland, Poland, and Spain. However, as production capacities rise, so does the importance of stable and efficient manufacturing processes. Even minor deviations in the concentration of metal ions or solids can affect the quality of the resulting cathode material and thereby impair battery performance. Precise process monitoring is therefore becoming a crucial factor for success.
OSCAR Research Project: In-line monitoring of technical fluids under high pressure
The goal of the OSCAR research project is the development of a novel optical high-pressure sensor system capable of monitoring the condition of technical fluids directly within the process and under real operating conditions.
What Is Viscosity? Measurement Principle and Inline Viscosity Measurement in Industrial Processes
Whether in coating processes, polymer production, or food manufacturing – viscosity directly influences product quality, process stability, and energy efficiency in many industrial applications. Even small changes in viscosity can indicate formulation deviations, process disturbances, or reaction progress. Continuous monitoring of this parameter is therefore crucial in numerous production processes. Modern inline viscosity sensors make it possible to measure viscosity directly in the ongoing process and under real operating conditions. This enables real-time process monitoring and early optimization of processes.
AAC and 3D Concrete Printing – How Modern Inline Measurement Technology Optimizes Production Processes
The building materials industry is facing increasing pressure to make production processes more efficient, sustainable, and stable. Precise inline measurement methods are gaining ever-greater importance, particularly in the production of autoclaved aerated concrete (AAC) and in the field of 3D concrete printing.
How Fluid.iO sensor data creates real added value
In modern industry, automation is the engine – and data is the fuel. But data alone does not create value. Only when it is reliably, quickly, and purposefully collected and processed can it unleash its full potential.
