First Generation of Advance Silicon-Based Anode Material Continues Delivering Strong Performance

• 18650 batteries testing continues to deliver 14% performance improvement versus graphite benchmark batteries with minimal battery degradation rates at 125 cycles ^[1].
  

MONTREAL, April 18, 2024 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: O08), a technology company specializing in green engineering of silica and silicon-based materials is pleased to announce continued milestones achieved by its France-based affiliate, NOVACIUM SAS ("Novacium"). This announcement highlights the promising results from ongoing cycle testing of 'industry standard' 18650 industrial batteries, notably at the 125-cycle mark. Additionally, it introduces the massive market opportunity for HPQ associated with advanced silicon-based anodes material manufacturing.

“The fact that our first generation of advanced silicon-based material continues to deliver about 3,100 milliampere-hour (mAh) of battery capacity after 125 cycles ^[1] is a powerful indication of the commercial potential of the materials we are developing for Advanced Mobile Technology applications, a US$ 228.9B addressable market in 2023 ^[2],” stated Dr. Jed Kraiem Ph.D., COO of Novacium. “These results underscore our ability to produce a blend of graphite and advanced engineered silicon anode material that can be seamlessly integrated into existing anode manufacturing facilities and utilized without requiring modification by battery manufacturers worldwide, all the while significantly enhancing the battery performances.”

CONTINUING TO DELIVER 14% BATTERY CAPACITY IMPROVEMENT AT 125 CYCLES

The data from Figure 1 below demonstrate that the three industrial-type batteries, which utilize Novacium's first generation of custom-engineered silicon material blend, (blue lines), continue to achieve > 14% performance improvement over 125 cycles. These batteries exhibit a high discharge capacity of approximately 3.10 Ampere-hours (Ah) (or about 3,100 mAh), surpassing the benchmark set by three comparison batteries (red lines) which have a capacity of about 2.65 Ah. These results, confirm and extend the approximate 14% enhancement in full-battery capacity compared to 100% graphite benchmark batteries, that was observed in the previous 5, 25, 50 and 100 cycles testing.
