HPQ Silicon Inc.: 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 ...

🔋 HPQ Silicon Inc. and Novacium achieved a new milestone with a semi-solid electrolyte drone battery pack delivering 395 Wh/kg at the pack level using GEN4 silicon anode material.

⚡ The newly developed 8S battery pack holds a capacity of 15,900 mAh and contains a total energy of 457 Wh within a mass of 1,160 g.

📊 This performance represents an estimated 23-36% improvement over selected publicly available lithium-polymer and NMC drone battery benchmarks.

🛠️ The GEN4 platform is proven to be format-flexible, having successfully demonstrated operation across cylindrical cells, liquid-electrolyte systems, and semi-solid architectures.

💬 Dr. Jed Kraiem of Novacium noted that the semi-solid electrolyte environment complements the structural stability engineered into GEN4 for high-capacity operation.

🌍 HPQ Silicon CEO Bernard Tourillon confirmed that these results validate GEN4 technology as not being limited to a single format or chemistry.

🚀 The battery solutions are positioned for scaling across targeted applications including mobility, defense, and advanced electronics.

🤝 HPQ has entered into an agreement with Apaton Finance GmbH to provide investor awareness and digital outreach services in Europe.

⚖️ The engagement with European-based firm Apaton covers an initial term of six months starting April 15, 2026, for €16,000 per month in cash consideration.

📰 HPQ Silicon Inc. is a Quebec-based company listed on the TSX Venture Exchange (TSX-V: HPQ) focused on advanced materials and critical process development.

Bullish Signals
  • HPQ Silicon Inc. and Novacium have achieved a breakthrough milestone with a semi-solid drone battery pack delivering 395 Wh/kg energy density, utilizing GEN4 silicon anode material.
  • This performance represents a significant estimated 23-36% improvement over selected publicly available LiPo and NMC drone battery pack benchmarks at the pack level.
  • The battery pack achieved 15,900 mAh capacity with a total energy of 457 Wh while maintaining a lightweight sub-1.2 kg mass.
  • GEN4 silicon anode material has now been validated as a flexible platform capable of operating across multiple battery architectures, including cylindrical, liquid-electrolyte, and semi-solid systems.
  • HPQ Silicon has demonstrated consistency with 21700 cylindrical cells exceeding 7,000 mAh per cell and various multi-configuration drone battery packs (8S2P, 8S3P, 6S3P).
  • The company has secured exclusive North American commercialization rights under the HPQ ENDURA+ brand, enabling access to industrial production capabilities across multiple formats.
  • HPQ has engaged Apaton Finance GmbH to provide investor awareness and digital outreach services starting April 15, 2026, to expand visibility among European and international investors.
Risk Factors
  • The test battery pack was produced by a 'commercial subcontractor' and tested under 'controlled conditions,' raising concerns about the readiness of manufacturing processes for immediate commercial scaling without proprietary factory access.
  • Performance metrics rely on comparisons to selected publicly available benchmarks, which may not account for specific proprietary technologies or application-specific constraints relevant to HPQ's actual target markets.
  • The battery pack weighs 1,160 g yet delivers only 457 Wh of total energy, resulting in a specific energy density that must be validated against rigorous real-world operational standards before widespread adoption.
  • The engagement with European-focused investor relations firm Apaton Finance GmbH for €16,000 per month indicates ongoing cash burn efforts to increase visibility, which may strain resources if commercial revenue does not materialize quickly.
  • The company is still in the technology validation and early communication phase, having only achieved initial test results with third-party contractors rather than demonstrating sustained production yields or partnerships with major OEMs.
Full Analysis
On April 30, 2026, HPQ Silicon Inc. announced a significant technological breakthrough in collaboration with Novacium, achieving a specific energy density of 395 Wh/kg for a semi-solid electrolyte 8S drone battery pack utilizing GEN4 silicon anode material. The high-performance battery pack demonstrated a capacity of 15,900 mAh and a total energy output of 457 Wh, with a total weight of 1,160 g. This performance represents an estimated 23% to 36% improvement over selected publicly available benchmarks for conventional lithium-polymer ("LiPo") drone batteries, which typically achieve between 150 and 220 Wh/kg at the pack level, as well as advanced lithium-ion systems ranging from 200 to 320 Wh/kg. The results confirm that GEN4 serves as a format-flexible platform, having been previously validated in 21700 cylindrical cells exceeding 7,000 mAh per cell and various multi-configuration drone battery packs including 8S2P, 8S3P, and 6S3P configurations. The success of this milestone was attributed by Dr. Jed Kraiem, COO of Novacium, to the ability of GEN4 silicon anode material to deliver consistent performance across different battery architectures when paired with a semi-solid electrolyte environment that complements the material's structural stability. Bernard Tourillon, President and CEO of HPQ Silicon, emphasized that this achievement validates GEN4 as a platform technology not limited to a single format or chemistry. Through its exclusive North American commercialization rights under the HPQ ENDURA+ brand, the company now possesses access to industrial production capabilities spanning multiple battery formats and chemistries, positioning it to scale high-performance solutions for applications in mobility, defense, and advanced electronics. Further technical details regarding benchmarking methodology and comparative energy density tables are available through a technical note and accompanying blog on the Company's website. In addition to its technical achievements, HPQ Silicon Inc. announced the engagement of Apaton Finance GmbH, a European-based capital markets communications firm headquartered in Hannover, Germany, to provide investor awareness and digital outreach services. The initial agreement commenced on April 15, 2026, for a term of six months with a cash consideration of €16,000 per month. The Company stated that Apaton Finance GmbH holds no securities of HPQ Silicon Inc., characterizing the parties as operating at arm's length. This strategic partnership aims to enhance the Company's visibility among European and international investors as it transitions from technology validation to commercial execution. HPQ Silicon Inc. remains a Quebec-based issuer on the TSX Venture Exchange with ticker symbols HPQ on the TSX-V, HPQFF on the OTCQB, and O08 on the FRA exchange.
