HPQ Silicon Starts Production of HPQ ENDURA+ 18650 and 21700 Cells
MONTREAL, Aug. 14, 2025 (GLOBE NEWSWIRE) — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company specializing in innovation in advanced materials and critical process development, announces the start of production of the first HPQ ENDURA+ cylindrical battery cells powered by Novacium’s [1] GEN3 silicon-based anode technology.
This first batch, consisting of 18650 and 21700 cells, is scheduled for delivery to HPQ by the end of September 2025. HPQ would also like to announce the completion and availability of the first technical datasheets for these cells, developed in collaboration with the manufacturer [2]. The datasheets highlight outstanding battery cell performance and provide information on dimensions and brand design. The document is now available for prospective customers and industrial partners.
Bernard Tourillon, President and CEO of HPQ Silicon Inc, said:
We are pleased to announce this next step in the commercialization of our HPQ ENDURA+ lithium-ion battery cells,
“The completion of technical datasheets formalizes market-readiness, and I’m very proud of the journey thus far.”
HPQ ENDURA+: higher energy density, 1,000 cycles, independently validated.
The HPQ ENDURA+ 18650 (4,000 mAh) and 21700 (6,000 mAh) cells offer increased energy density and a lifespan approaching 1,000 full charge–discharge cycles, validated by independent testing [3]. This milestone represents a key step in the commercialization of our batteries, enabling their seamless integration into a broad range of high-capacity energy applications, including mobility, power tools, consumer electronics, telecommunications (civil and military), and energy storage systems.
HPQ ENDURA+ brand and Market Opportunity
This announcement builds on HPQ’s recent developments, including the launch of the HPQ ENDURA+ brand and the signing of strategic agreements to accelerate the commercialization in North America of lithium batteries incorporating GEN3 silicon-based materials. With the global lithium-ion battery market expected to grow from US$15.92 billion to US$45.6 billion by 2033 [4], HPQ is well-positioned to capitalize on this expansion through its innovations in silicon-based materials.
Mr. Tourillon, added:
We continue to receive inquiries from global potential customers and are engaging in technical discussions with leading industry players,
“This confirms the growing interest in our battery technology and HPQ ENDURA+ cells. These interactions have allowed us to refine our specifications to better meet market needs. With production now underway, we anticipate an acceleration of partnership opportunities as soon as we start delivery.”
