HPQ Silicon's ENDURA+ Gen4 Lithium-Ion Cells Achieve UL 1642 Safety Certification

HPQ Silicon Inc. has confirmed that its HPQ ENDURA+ Gen4 21700 lithium-ion cell platform has successfully obtained UL 1642 safety certification from an accredited independent testing laboratory. This milestone validates the cells' compliance with one of the most recognized U.S. safety standards for commercial lithium-ion cells.

The certification is a significant step in the commercialization of HPQ's silicon-anode battery technology. The UL 1642 approval supports customer qualification programs, battery pack integration, and commercial evaluations with prospective industrial partners.

The new Gen4 cell platform is certified at a capacity of 6,500 mAh, an 8.3% increase over the previously certified Gen3 platform, which has a capacity of 6,000 mAh. This performance improvement was achieved while meeting stringent safety and reliability requirements necessary for commercial deployment.

The technological advancement addresses the growing global demand for higher-energy lithium-ion batteries in applications such as mobility, energy storage, and telecommunications. Independent certification provides customers and manufacturers with increased confidence as they evaluate next-generation cell platforms for commercial use.

HPQ Silicon President and CEO Bernard Tourillon stated that independent certification is crucial for transforming advanced battery technology into a commercially viable product. He added that the certification strengthens the company's commercialization strategy by providing assurance to customers and industrial partners evaluating the technology for future applications.
