Battery manufacturing is one of the most demanding industrial production processes of our time. Whether lithium-ion batteries for e-mobility, stationary energy storage, or industrial applications—maximum product quality, process stability, and safety are indispensable. A key factor often overlooked is professional sampling.
电池制造堪称当今最要求严格的工业生产流程之一。无论是用于电动交通工具、固定式能源存储还是工业领域的锂离子电池，确保最高的产品质量、工艺稳定性和安全性都是不可或缺的。不过，有一个关键因素常常被忽视，那就是专业的样品检测工作。

It forms the basis for reliable analyses, stable processes, and reproducible product quality—from raw material preparation to electrode production.
从原材料的准备到电极的制造，这一过程为确保分析结果的可靠性、生产工艺的稳定性以及产品质量的可重复性奠定了基础。

Why Sampling Is Critical in Battery Technology
为什么抽样在电池技术中至关重要

Battery technology involves highly sensitive, mostly powder-based materials. Even minimal deviations in particle size, chemical composition, or moisture can directly affect a cell’s performance and lifespan. At the same time, requirements for purity, traceability, and process control continue to rise.
电池技术涉及各种高度敏感的原材料，这些材料大多以粉末形式存在。哪怕颗粒大小、化学成分或含水量有微小的偏差，都可能直接影响电池的性能和使用寿命。与此同时，对材料的纯度、可追溯性以及生产过程的控制要求也不断提高。

Technically precise, automated sampling ensures that these parameters can be monitored reliably—without disrupting production or contaminating the product.
通过精确的自动化采样方式，可以确保这些参数得到可靠的监测——而不会干扰生产过程或导致产品受到污染。

Sampling Along the Entire Battery Process Chain
贯穿整个电池生产流程的采样检测

Quality-relevant monitoring begins with the raw materials used. Materials such as nickel, cobalt, lithium, or manganese compounds pass through multiple processing stages before becoming active battery materials. Further downstream, sulfates, carbonates, and hydroxides are produced and later converted into cathode and anode materials, such as graphite or cathode powders.
与质量相关的监控工作，是从所使用的原材料开始的。镍、钴、锂或锰等化合物在成为可用于制造电池的材料之前，需要经过多道加工工序。在后续的工艺中，会生成硫酸盐、碳酸盐和氢氧化物，这些物质再被转化为正极和负极材料，比如石墨或正极粉末。

Representative sampling is required at every stage to ensure compliance with defined specifications and to detect deviations early.
在每个阶段都需要进行代表性抽样，以确保符合既定的技术规范，并能及时发现任何偏差。

Technical Requirements for Modern Sampling Solutions
现代采样解决方案的技术要求

The unique properties of battery-relevant powders place high demands on sampling systems. Many materials are abrasive, extremely fine, or sensitive to oxygen and moisture. Sampling therefore must:
与电池相关的各种粉末具有独特的性质，这就对采样系统提出了很高的要求。许多这类材料具有研磨性、颗粒极其细微，或者对氧气和湿气极为敏感。因此，采样过程必须做到：

• be contamination-free, 无污染。
• reliably maintain any protective atmosphere,
  能够可靠地维持任何所需的保护性气氛。
• ensure high tightness against the environment,
  确保能够有效防止外界物质进入，保持高度的密封性。
• while remaining flexible enough to adapt to different process conditions.
  同时，还具有足够的灵活性，能够适应不同的工艺条件。

Coated, product-contacting components help prevent material interactions and increase system service life. At the same time, customer-specific adaptations enable optimal integration into existing plants.
经过特殊处理的、与产品直接接触的部件，有助于避免各种材料之间的相互作用，从而延长系统的使用寿命。同时，根据客户的具体需求进行定制，还能确保这些部件能够完美地融入现有的生产设备中。

Representative Sampling from Continuous Material Flows
连续物料流中的代表性抽样方法

In many areas of battery manufacturing, powders are transported continuously. Here, sampling directly from the drop pipe has become established. Specially designed cup samplers take defined sample volumes directly from the free-falling material stream.
在电池制造的许多环节中，粉末需要被持续不断地输送。在这种情况下，直接从输送管道中取样已成为常规做法。专门设计的采样装置能够直接从自由落下的粉末流中采集指定量的样品。

The major advantage: sampling is reproducible and does not interfere with ongoing production. By selecting different pipe diameters and variable cup geometries, the sample quantity can be precisely tailored to subsequent analytical requirements—an essential factor for reliable quality data.
其主要优点在于：取样过程具有可重复性，且不会干扰正常的生产流程。通过选择不同的管道直径和杯状结构的尺寸，可以精确控制取样量，从而满足后续分析的需要。这一点对于获得可靠的质量数据至关重要。

Sampling from Reactors and Buffer Tanks
从反应器和缓冲罐中取样
In reactors or buffer containers—such as during discontinuous process steps—targeted extraction from a defined depth is required. Screw-based sampling systems enable controlled collection even at large fill levels.
在反应器或缓冲容器中——尤其是在那些需要间歇性操作的工艺过程中——必须能够从特定深度处有针对性地提取样品。基于螺旋装置的采样系统即便在容器内物质填充量很大的情况下，也能实现精确的采样。

This type of sampling provides valuable information on material homogeneity and the progress of chemical reactions. Thanks to compact design and modular construction, such systems can be integrated flexibly and serviced easily—an important contribution to plant availability.
这种采样方式能够提供有关材料均匀性以及化学反应进展的宝贵信息。由于具有紧凑的设计和模块化结构，这类系统易于集成和保养，从而显著提升了设备的可用性。

Automation as a Key to Process Reliability
自动化是确保流程可靠性的关键所在

Today’s sampling solutions are fully integrated into plant and process control. Automated sequences, decentralized controls, and integrated sensors ensure consistently high sample quality and minimize manual intervention.
如今的采样解决方案已完全融入到工厂和工艺控制系统中。自动化的操作流程、分散式的控制方式以及集成的传感器共同确保了样品质量的稳定性，同时最大限度地减少了人工干预的需要。

Direct connection to the control system enables seamless documentation, supports traceability, and forms the basis for data-driven process optimization—a clear advantage in highly regulated production environments.
与控制系统的直接连接使得文档记录更加便捷，有助于实现追溯性。同时，这也是实现数据驱动型流程优化的基础。在监管严格的制造环境中，这一优势尤为明显。

Sampling Determines Quality and Competitiveness
抽样决定了产品的质量和竞争力。

In battery manufacturing, sampling is far more than an auxiliary analytical step. It is a central element of process management and a decisive lever for quality, safety, and efficiency. Those who rely on automated, contamination-free, application-optimized sampling solutions create the foundation for stable processes and high-quality battery materials—today and in the future.
在电池制造过程中，取样绝不仅仅是辅助性的分析步骤。它其实是流程管理中的关键环节，对确保质量、安全与效率起着决定性作用。那些采用自动化、无污染且经过优化设计的取样方案的企业，才能为打造稳定可靠的制造流程以及高品质的电池材料奠定基础——无论是现在还是未来。
