HPQ and Novacium Achieve 395 Wh/kg in Semi-Solid Drone Battery Pack Using GEN4 Silicon Anode Material and Announces Engagement of European Focused Investor Awareness & Digital Outreach Services Semi-solid 8S drone battery pack incorporating GEN4 silicon anode material delivers 15,900 mAh and 395 Wh/kg at the pack levelPerformance represents an estimated 23–36% improvement over selected publicly available LiPo and NMC drone battery pack benchmarks at the pack level [1]Results further support GEN4 as a format-flexible platform, now demonstrated across multiple battery architectures, including cylindrical, liquid-electrolyte, and semi-solid systems MONTREAL, April 30, 2026 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), today announced that a semi-solid electrolyte 8S drone battery pack integrating Novacium’s GEN4 silicon anode material has achieved 15,900 mAh capacity, 457 Wh total energy, and 395 Wh/kg at the pack level. The battery pack, weighing 1,160 g, was produced by a commercial subcontractor and tested under controlled conditions [2]. Conventional lithium-polymer (“LiPo”) drone battery packs typically achieve approximately 150–220 Wh/kg at the pack level, while more advanced lithium-ion and optimized drone battery systems generally range between 200–320 Wh/kg, based on publicly available data [1]. The GEN4 semi-solid configuration delivers 395 Wh/kg [3], representing an estimated 23–36% improvement over selected publicly available drone battery pack benchmarks, while maintaining a sub-1.2 kg pack mass[2]. “These results highlight GEN4’s ability to deliver consistent performance across different battery architectures,” added Dr. Jed Kraiem, COO of Novacium. “The semi-solid electrolyte environment complements the structural stability engineered into GEN4, enabling high-capacity operation.” These results further support GEN4 silicon anode material as a platform technology capable of operating across multiple battery architectures. Performance has now been demonstrated across: 21700 cylindrical cells exceeding 7,000 mAh [4],multi-configuration drone battery packs (8S2P, 8S3P, 6S3P) [5], andsemi-solid electrolyte systems, as reported in recent releases. “This new mileston...
