Reliable Leak Detection for Efficient Battery Cell Production
Battery Cell Production Under Pressure—Supporting Quality, Safety, and Throughput Across the Entire Battery Cell Value Chain
Battery cell manufacturing combines high energy density, strict safety requirements, and demanding throughput targets. Process stability is essential, yet even small deviations can affect yield, quality, and safety. Many manufacturers face similar challenges across the entire value chain.

Catch microscopic sealing defects and welds early. Detect leaks below conventional limits, and inspect every cell without slowing the line.
Spot electrolyte loss, gas buildup, or pressure shifts before failures surface—catching issues early, before most value is added.
Quality control that scales with line speed: automated, sensitive inspection that fits within cycle time, no manual bottlenecks.
Verify sealing integrity in-line, without sacrificing throughput.
Leak detection as a process and quality control element
Leak detection plays a central role in stabilizing battery cell production. When leaks are identified early, defective cells can be removed before downstream value is added. Process deviations become visible sooner, corrective actions can be taken faster, and quality data becomes more transparent.
Rather than acting as a final inspection step, leak detection can support process control across critical manufacturing stages.

As battery cell designs evolve and production speeds increase, manufacturers face growing challenges in detecting ever-smaller leaks without slowing down throughput. This article addresses issues such as insufficient test sensitivity after electrolyte filling, limitations of helium-based methods, and the need to test larger assemblies and new cell chemistries. It shows how higher sensitivity and faster inline testing help protect quality, yield, and future production scalability.
Micro-defects can form in battery cells during welding and handling—even after they've passed initial leak testing. The BES4000 uses electrolyte sniffing to locate these leaks directly on assembled modules and packs in under a second, enabling targeted rework instead of costly chamber retesting. Paired with the ELT series, it closes the loop from cell validation to full pack testing.
Helium background and long pump-down times are common challenges in industrial leak testing, often limiting throughput and increasing operating costs. This article addresses these issues by explaining how EcoBoost helps manufacturers maintain sensitivity even with elevated helium backgrounds, enabling faster cycle times, lower helium consumption, and higher system availability. It focuses on improving process stability without compromising measurement reliability.
Sodium-ion battery cells introduce new cost advantages, but they do not reduce the demands on quality assurance. Manufacturers face similar challenges as with lithium-ion technology, including electrolyte loss, moisture ingress, and long-term capacity degradation caused by leaks. This article explains why proven leak rate requirements and testing strategies remain essential when scaling sodium-ion cell production.
Rising helium costs and limited availability are putting pressure on leak testing operations, especially in high-volume vacuum applications. This article addresses common challenges such as maintaining measurement accuracy with lower helium concentrations, avoiding longer cycle times, and ensuring reliable calibration. It shows how manufacturers can significantly reduce helium consumption without compromising sensitivity or process stability.
After electrolyte filling, many manufacturers struggle with leak testing methods that no longer deliver reliable results. This article explains why helium bombing can miss critical leaks in liquid-filled battery cells, creating a false sense of quality and increasing the risk of late failures. It highlights the challenge of detecting electrolyte-wetted leaks and shows why alternative testing principles are required.
