Quality control in a production plant shows its maximum potential in the form of inline measurements. Defects and imperfections can be detected early and directly, and waste and costs can be reduced. Nuclear Magnetic Resonance offers a wide range of applications but requires dedicated adaptation to the respective process and material conditions. A V-shaped low-field NMR sensor was developed for non-invasive inline measurements on anode slurries in a battery production plant. In battery production, inline monitoring of the quality of anode slurries is demanded, offering the possibility of predictive control of the following process steps. Methods of low-field NMR to determine flow properties were adapted to the desired application. Further, magnetic resonance imaging measurements were made to determine the flow properties of model substances and anode slurries, thus providing verification. The sensor measurements show the ability to measure the flow behavior of, amongst other fluids, anode slurries in a form suitable for inline quality control in a battery production plant.
生产工厂中的质量控制以内联测量的形式展现出其最大潜力。缺陷和瑕疵能够被早期且直接地检测到，同时浪费和成本得以降低。核磁共振有广泛的应用，但需要针对各自的工艺和材料条件进行专门适配。为一家电池生产工厂中对阳极浆料进行非侵入式内联测量，研发了一种V形低场核磁共振传感器。在电池生产中，需要对阳极浆料的质量进行内联监测，以便对后续工艺步骤进行预测性控制。用于确定流动特性的低场核磁共振方法已适配到所需应用中。此外，还进行了磁共振成像测量以确定模型物质和阳极浆料的流动特性，从而提供验证。传感器测量结果表明，该传感器能够以适合电池生产工厂内联质量控制的形式测量阳极浆料等多种流体的流动行为。
