07:54 AM EDT, 08/21/2024 (MT Newswires) -- HPQ Silicon ( HPQFF ) , a technology company specializing in green engineering of silica and silicon-based materials, announced Wednesday the "latest significant battery milestones" achieved by its France-based affiliate, NOVACIUM SAS.

A statement noted this announcement covers the results of 50 charge-discharge cycle tests conducted to simulate real-world usage and assess the durability and longevity of the latest batch of Lithium-ion 18650 commercial batteries, made with a blend of graphite and Novacium's partially optimized GEN3 advanced silicon-based anode material.

HPQ said the 18650 GEN3-based batteries performed "remarkably well", with an overall capacity improvement of about 40% compared to a graphite benchmark. It added this performance is 25% higher than that of the previous GEN1 material and 15% higher than that of the GEN2 material, with performance degradation so minimal compared to the graphite benchmark that it falls within the margin of error.

"Producing 18650 battery cells that excel in charge-discharge cycle testing and exceed 4,000 mAh under maximum discharge conditions....further confirms our position as a top-tier producer of advanced silicon anode material," said Dr. Jed Kraiem, COO of Novacium. "Based on these results and the data we've gathered, we are confident that we can continue improving our material, and that GEN4-based 18650 batteries could exceed the 4,400 mAh mark."

HPQ edged up $0.005 to $0.345 on Tuesday.
