WAYEAL Showcases Battery Safety Leak Testing Solutions at CIBF 2026

From May 13 to 15, 2026, the 18th China International Battery Fair (CIBF 2026) was held at Shenzhen World Exhibition and Convention Center. According to the official CIBF introduction, the exhibition was scheduled to bring together more than 3,000 exhibitors across battery materials, equipment, cell manufacturing, pack technology, and recycling.

For battery manufacturers, the message behind the exhibition was clear: new energy technology is moving quickly, but safety remains the first threshold every product must pass. WAYEAL joined the event in Hall 16, Booth 16T019, presenting lithium battery life-cycle leak testing solutions for cell manufacturing, module assembly, Pack-level sealing, and related production quality control.

Leak Testing For The Battery Safety Baseline

At the booth, WAYEAL focused on three core inspection areas: helium mass spectrometer leak detection, air tightness leak testing, and lithium battery vacuum chamber leak detection systems. These technologies help manufacturers identify small leakage paths before they become safety, reliability, or yield risks.

For high-sensitivity helium testing, the SFJ-231 mobile helium mass spectrometer leak detector was presented as a practical tool for fast response, low leak-rate detection, and background recovery when helium contamination raises the baseline. WAYEAL also highlighted the SFJ-16M modular helium leak detector, a compact platform designed for integration into automated production equipment where footprint and cycle time both matter.

From Instruments To Integrated Systems

Battery leak testing is rarely only an instrument decision. Cell covers, battery cells, modules, water-cooling plates, and Pack assemblies all have different part sizes, sealing structures, leak-rate targets, and handling requirements. That is why WAYEAL also introduced customized lithium battery vacuum chamber leak detection systems built around specific production scenarios.

Compared with traditional bubble testing or pressure decay methods, helium mass spectrometry offers high sensitivity, fast response, and non-destructive testing advantages. For battery manufacturers working with higher energy density, larger energy storage cells, and tighter Pack-level sealing requirements, these advantages can help improve confidence in sealing integrity across the full product life cycle.

WAYEAL’s air tightness testing portfolio was also part of the display. The CH600 single-channel air tightness leak detector and ZH600 series products showed how pressure-based methods can support traceable production inspection. The sixth-generation air tightness platform supports large-volume data storage and rapid data retrieval, helping production teams connect leak test results with quality records and process improvement.

Live Demonstrations And Application Conversations

During the exhibition, the live helium leak detector demonstration area attracted visitors from lithium battery manufacturing, energy storage system integration, automotive components, and testing services. WAYEAL’s technical team used on-site operation and real-time explanation to discuss practical concerns such as cycle time, leak-rate criteria, fixture design, data traceability, and customized system configuration.

Several visitor discussions centered on high-pressure sealed parts and Pack-level inspection, where sealing integrity has become a critical checkpoint for energy storage reliability. As battery technology continues to diversify across lithium-ion, sodium-ion, solid-state, and other emerging routes, leak testing remains a shared requirement: every product still depends on dependable sealing before it can safely enter service.

CIBF 2026 reinforced that battery safety is not a single test at the end of production. It is a manufacturing discipline built from precise measurement, repeatable processes, and equipment that fits the real production line. WAYEAL will continue to develop helium leak detection, air tightness testing, and vacuum chamber system solutions to help battery and new energy manufacturers find each small leak before it becomes a larger risk.
