Oregon (Shiyan) Amperex Technology Elevates Standards with Rigorous Packaging Stage QC for Prismatic Lithium-ion Cells

Shiyan, China – May 29, 2025 – Oregon (Shiyan) Amperex Technology, a leading innovator in advanced battery solutions, today underscored its unwavering commitment to quality by detailing its stringent quality control (QC) protocols specifically implemented during the critical packaging stage of its prismatic lithium-ion battery cell production. Recognizing that packaging integrity is paramount for safety, performance, and longevity, the company has established multi-layered inspection systems to ensure every cell meets the highest global standards before leaving the facility.

Why Packaging QC is Critical

The final packaging phase is a decisive point in the battery manufacturing process. It involves sealing the sensitive prismatic cell within its protective casing, applying essential labeling, and preparing it for shipment. Compromises at this stage – such as inadequate sealing leading to moisture ingress, physical damage from insufficient cushioning, or incorrect labeling – can have severe consequences, including reduced performance, safety hazards, or premature failure in end-user applications like electric vehicles (EVs) and energy storage systems (ESS).

Oregon (Shiyan) Amperex's Multi-Pronged Packaging QC Approach

Oregon (Shiyan) Amperex Technology has implemented a robust QC regime targeting the packaging stage:

Advanced Sealing Integrity Verification: Utilizing state-of-the-art leak detection systems (including helium leak testing where applicable) to ensure hermetic seals that prevent electrolyte leakage and moisture contamination, critical for cell lifespan and safety.

Automated Visual Inspection (AVI): High-resolution cameras and AI-powered vision systems meticulously scan every cell post-packaging. They check for:

Surface defects (dents, scratches, deformities) on the casing.

Precise alignment and application of terminals and safety vents.

Accuracy, legibility, and correct placement of all labeling and barcodes (including batch codes, QR codes, voltage, capacity, and safety certifications).

Dimensional & Weight Checks: Automated systems verify the final dimensions and weight of each packaged cell against strict tolerances, ensuring consistency and identifying any deviations that might indicate internal issues or packaging flaws.

Electrical Safety Re-Test: A final electrical safety check (e.g., insulation resistance, Hi-Pot testing) is often performed after packaging to confirm no damage occurred during the sealing and handling process.

Traceability Reinforcement: The packaging stage reinforces the company's comprehensive traceability system. Every label and code applied is meticulously linked back to the specific production batch, materials used, and QC data, enabling full traceability throughout the supply chain.

Robust Packaging Validation: The materials and design used for secondary packaging (trays, boxes) are rigorously tested to ensure they provide optimal protection against shock, vibration, compression, and environmental factors during transport and storage.

Commitment to Excellence

"Quality isn't just about the internal chemistry of our prismatic lithium-ion cells; it extends seamlessly to how we protect and present them to our customers," stated Lena, Director at Oregon (Shiyan) Amperex Technology. "Our zero-tolerance approach to defects during the packaging stage is a fundamental pillar of our brand promise. By investing in cutting-edge inspection technology and enforcing rigorous protocols at this final hurdle, we deliver cells that customers can integrate into their high-performance applications with absolute confidence in reliability and safety."

This focus on packaging-stage QC complements Oregon (Shiyan) Amperex Technology's existing stringent controls throughout raw material sourcing, electrode manufacturing, cell assembly, and formation. The company adheres to international standards, including UN38.3, IEC 62133, and relevant customer-specific requirements.
