HPQ Silicon and its French partner Novacium have confirmed that their lithium‑ion cells have now achieved IEC 62133 certification, marking a significant step toward wider global deployment.
The approval places the companies’ cylindrical 18650 and 21700 formats – already used across consumer electronics, industrial tools, medical devices and laboratory equipment – within the world’s most recognised safety framework for portable rechargeable batteries.
IEC 62133 is regarded as the leading international benchmark for lithium‑ion cell and pack safety, required or strongly preferred across Europe, Asia and many other regions. The standard assesses electrical, mechanical and chemical safety under both normal operation and foreseeable misuse, alongside requirements for labelling, documentation and traceability.
This latest certification completes the trio of major global safety approvals for HPQ and Novacium, following earlier UN 38.3 transport compliance and UL 1642 certification. Together, these remove key regulatory barriers and open the door to broader commercial engagement with OEMs.
“This is a critical commercial milestone for HPQ and Novacium,” said Bernard Tourillon, chairman, president and CEO of HPQ Silicon. He noted that the combined certifications allow the companies to progress from technical assessments to commercial negotiations and supply‑chain integration.
Derick Lila, HPQ’s director of communication and director of business development, added that “IEC 62133 dramatically broadens our market reach,” enabling customers to move confidently from testing to procurement.
With this approval in place, HPQ and Novacium aim to accelerate qualification programmes, expand customer discussions, and advance their strategy to scale production of high‑value, market‑ready energy storage solutions.
