June 23, 2025 – Hsinchu, Taiwan – ACE Systemtek has partnered with TeraView to introduce the battery testing solution, BTS TeraCota 3500, a cutting-edge solution that redefines battery cell inspection by offering smarter, safer, and more efficient quality control. As global demand for electric vehicles (EVs) and energy storage systems continues to rise, so do the expectations for battery performance and safety. Mr. Yong Seok (YS) Chang, Vice President of Sales for Asia at TeraView, highlighted the increasing importance of advanced inspection technologies in ensuring battery reliability. "Taiwan's deep technological expertise and collaborative culture create an environment ripe for innovation in the battery sector," said YS Chang. 

Discussing key production processes such as coating, drying, and calendaring, YS Chang emphasized the critical role of precision. "Porosity and density in electrodes directly affect battery performance and safety parameters that must be tightly controlled, so next-generation inspection technologies are essential." Traditional inspection techniques—including X-ray, beta/gamma radiation, infrared laser triangulation, and ultrasound—often face limitations in identifying internal defects, structural inconsistencies, or metallic impurities. "These methods can require physical contact, pose radiation risks, and need frequent recalibration," YS Chang added.

In contrast, the battery testing solution BTS TeraCota 3500 leveraged TeraView’s terahertz (THz) waves to deliver non-destructive, contactless inspection of electrode sheets. "Our system can measure coating thickness, basis weight, density, and conductivity using reflected THz signals—without ionizing radiation or physical contact, and with minimal calibration," YS Chang explained. "This translates into higher accuracy, improved safety, and seamless integration into modern manufacturing lines." YS Chang believes terahertz inspection is becoming indispensable for battery manufacturers striving to remain competitive. "As battery designs become more complex, detecting micro-defects and compositional anomalies that traditional methods might miss is crucial. Terahertz technology offers that critical level of visibility."

He also shared successful case studies where the battery testing solution BTS TeraCota 3500 significantly improved product quality and reduced defect rates. "Customer feedback has been overwhelmingly positive, with some clients reporting higher yields and fewer downstream quality issues," said YS Chang.

With this strategic collaboration, ACE Systemtek and TeraView are well-positioned to lead the next wave of battery manufacturing innovation. Both companies believe terahertz-based inspection technology will provide a significant competitive advantage.
