Engineered silicon-based anode.
From engineered silicon materials to certified commercial cells
HPQ’s battery platform integrates advanced silicon-based anode materials with commercially qualified lithium-ion cell manufacturing.
Developed in partnership with Novacium SAS, GEN3 silicon anode materials are engineered for seamless integration into existing lithium-ion production lines.
These materials now power HPQ ENDURA+ 18650 and 21700 cells — marking the transition from upstream materials innovation to downstream commercial battery products.
The platform is designed for scalability, manufacturability, and near-term industrial deployment.
18650 ENDURA+ cell capacity achieved
Validated charge cycles with sustained performance
Opportunity.
Global lithium-ion demand continues to expand across electric mobility, computing, communication devices, and grid storage systems.
Silicon has long been recognized as a superior anode material due to its significantly higher theoretical capacity than graphite. However, traditional silicon solutions have struggled with swelling, degradation, and manufacturing compatibility.
Battery manufacturers require performance improvements without costly redesign of existing production infrastructure.
A scalable, industrially compatible silicon solution represents a structural opportunity within the battery value chain.
Solution.
HPQ’s proprietary semi-continuous process produces engineered silicon-based anode materials optimized for integration within existing lithium-ion manufacturing lines.
GEN3 materials have demonstrated capacity exceeding graphite benchmarks while maintaining 80% retention beyond 1,000 cycles in commercially sized cells.
HPQ ENDURA+ 18650 (4,000 mAh) and 21700 (6,000 mAh) cells have been produced and certified for commercial distribution.
Non-dilutive government funding of up to $3 million supports development of a 50 TPY continuous production system to scale silicon material output.
