HPQ Silicon begins production of Endura+ battery cells

Mr. Bernard Tourillon reports HPQ SILICON STARTS PRODUCTION OF HPQ ENDURA+ 18650 AND 21700 CELLS HPQ Silicon Inc. has started production of the first HPQ Endura+ cylindrical battery cells powered by Novacium SAS's 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 data sheets for these cells, developed in collaboration with the manufacturer. The data sheets highlight outstanding battery cell performance and provide information on dimensions and brand design. The document is available for prospective customers and industrial partners. "We are pleased to announce this next step in the commercialization of our HPQ Endura+ lithium-ion-battery cells," said Bernard Tourillon, president and chief executive officer of HPQ Silicon. "The completion of technical data sheets formalizes market readiness, and I'm very proud of the journey thus far." HPQ Endura+: higher energy density, 1,000 cycles and independently validated The HPQ Endura+ 18650 (4,000 milliampere-hour) and 21700 (6,000 milliampere-hour) cells offer increased energy density and a lifespan approaching 1,000 full charge-discharge cycles, validated by independent testing. This milestone represents a key step in the commercialization of its 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 $15.92-billion (U.S.) to $45.6-billion (U.S.) by 2033, HPQ is well positioned to capitalize on this expansion through its innovations in silicon-based materials. "We continue to receive inquiries from global potential customers and are engaging in technical discussions with leading industry players," added Mr. Tourillon. "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 under way, we anticipate an acceleration of partnership opportunities as soon as we start delivery." About HPQ Silicon Inc. HPQ Silicon is a Quebec-based TSX Venture Exchange industrial issuer. HPQ is a technology company focused on innovation in advanced materials and critical process development. In partnership with world-class technology leaders PyroGenesis Inc. and Novacium -- of which HPQ is a shareholder -- the company is developing the materials and process technologies essential to achieving net-zero goals. HPQ activities are centred around the following pillars: Becoming a green, low-cost (capital expenditures and operating expenditures) manufacturer of fumed silica using the fumed silica reactor, a proprietary technology owned by HPQ Silica Polvere Inc., being developed for HSPI by PyroGenesis; Working with research and development partner Novacium to become a producer of silicon-based anode materials for battery applications; Developing innovative processes to generate and use hydrogen: Metagene, a low-carbon, chemical-based, on-demand, high-pressure autonomous hydrogen production system, is being developed by Novacium of which HPQ holds the exclusive North American (Canada, United States and Mexico) licence; Waste to energy, a new process to transform black aluminum dross into a valuable resource, is being developed by Novacium, of which HPQ holds the exclusive North American (Canada, United States and Mexico) licence; Becoming a zero-carbon-dioxide low-cost (capex and opex) producer of high-purity silicon (2N+ to 4N) using its Purevap quartz reduction reactors, a proprietary technology owned by HPQ being developed for HPQ by PyroGenesis.
