HPQ Silicon Secures UN 38.3 Certification for HPQ ENDURA+ 18650 & 21700 Cells

Executive Summary

• HPQ Silicon Inc. obtained UN 38.3 certification for its first high‑performance lithium‑ion cells (18650 – 4,000 mAh and 21700 – 6,000 mAh) in the ENDURA+ line.
• Certification validates safety and transport compliance, enabling global shipping, distribution, and industrial adoption of the cells.
• The company plans to pursue UL1642 certification for U.S. market entry and targets production capacity of up to 1.5 million cells per year through its partnership with Novacium SAS.

Key Details

• Certification: UN 38.3 granted by an accredited independent laboratory after passing all eight mandatory tests (altitude simulation, thermal cycling, vibration, shock, external short circuit, crush/impact, overcharge, forced internal short).
• Cell Specifications:
• 18650 format – 4,000 mAh, >300 Wh/kg, ~1,000 charge‑discharge cycles.
• 21700 format – 6,000 mAh, >300 Wh/kg, ~1,000 charge‑discharge cycles.
• Regulatory Impact: Certification confirms compliance with international safety and transport standards, allowing shipment by air, sea, or land worldwide.
• Commercial Strategy:
• Enables immediate shipping to customers and industrial partners in North America and internationally.
• Accelerates commercial discussions and supply agreements.
• Production Capacity: Planned scaling to up to 1.5 million cells per year via third‑party production lines with Novacium SAS.
• Next Milestone: Pursuing UL1642 certification for the U.S. market; most UL‑related tests already completed internally by Novacium’s engineering team.
• Leadership Quote: Bernard Tourillon, President & CEO, highlighted the transition from R&D to a fully compliant commercial phase and emphasized safety validation.
