Recognised as a leading specialist in battery leakage detection in China, HIRAYS was invited to attend. Mr. Shen, Director of HIRAYS' R&D Centre, served as the invited guest speaker and presented the company's advanced RGA (residual gas analysis) quadrupole mass spectrometry-based electrolyte leakage detection solution.

As the new national standard for power banks moves towards implementation, trace electrolyte leakage has become a key control item under CCC certification, and power bank manufacturers are required to establish 100% leakage testing capability. Conventional methods are susceptible to interference from adhesive and cleaning-agent vapours as well as cell deformation, making it difficult to identify micro-leak defects with precision and hindering manufacturers' efforts to put compliant quality inspection into practice. Addressing these industry pain points, Mr. Shen systematically compared the strengths and limitations of leakage detection methods currently available on the market, and identified quadrupole mass spectrometry as the optimal technical route for aligning with the new rules and meeting high-precision inspection requirements.

During the session, Mr. Shen also introduced HIRAYS' in-house RGA quadrupole mass spectrometry-based electrolyte leakage detection system. Developed specifically to address the new national standard for power banks and the associated CCC certification requirements, the system extends a mature electrolyte leakage detection approach proven in the traction battery sector into the CCC-regulated power bank segment. It identifies trace electrolyte leakage with high specificity while effectively eliminating interference from vapours given off by adhesives and cleaning agents, fully satisfying the stringent compliance requirements of the updated rules.

The system has now been deployed at scale across the production lines of leading consumer electronics brands and top-tier contract manufacturers in China and overseas. Validated over sustained high-volume production, it has earned broad industry recognition for its operational stability, detection accuracy and standards compatibility.

During the interactive Q&A session, participating companies raised a wide range of practical questions covering production-line deployment at scale, key points of compliance audits, equipment calibration procedures and product compatibility. Drawing on hands-on experience from multiple HIRAYS deployments, Mr. Shen offered tailored, end-to-end solutions that addressed the practical bottlenecks and pain points companies face when implementing compliant quality inspection. His responses were well received by attendees.

The training helped align the industry's understanding of compliance standards for power banks, lithium-ion batteries and related products, gave manufacturers a thorough grasp of the latest technical specifications and the mandatory CCC certification requirements, and further reinforced their primary responsibility for product quality and safety.

As a core technology provider for seal and leakage testing in lithium batteries and power banks, HIRAYS will continue to deepen its focus on electrolyte leakage detection, progressively upgrade its trace-leakage detection technology portfolio for batteries and power banks, and deliver professional compliance support to help the power bank and lithium-ion battery industries raise quality standards and upgrade their capabilities.
