A recent recall of over 1.2 million power banks due to fire risks has sparked widespread concern in China. The issue stemmed from metallic contaminants in lithium battery cells, which can pierce the internal separator and trigger dangerous short circuits. In response, the Civil Aviation Administration of China (CAAC) now bans power banks without 3C certification or from recalled batches on domestic flights.

According to CCTV investigations, these tiny impurities—introduced during battery manufacturing due to aging equipment—pose significant safety risks. Experts emphasize that lithium batteries are the core of power banks, and their safety determines the overall device integrity.

Ray Tech Malaysia parent company, Unicomp Technologies, a leader in X-ray inspection, offers a powerful solution. Their advanced systems can detect internal metal defects in various lithium cells, including 18650, 21700, and lithium polymer types. This non-destructive method reveals hidden flaws early, ensuring product safety and preventing recalls.

X-ray inspection is now a critical step in modern battery production, from electrode sheet preparation to final quality checks. It boosts manufacturing efficiency, reduces defect rates, and ensures only top-quality batteries reach the market.

By adopting Unicomp’s X-ray technology, battery manufacturers can strengthen product safety, protect brand reputation, and maintain a competitive edge in a market increasingly driven by quality and trust.
