Novacium’s Silicon-Anode Batteries Achieve 900+ Cycle Efficiency, Outperforming Leading 18650 Cells

Core Insights - HPQ Silicon Inc. has reported exceptional battery performance results from its partner, NOVACIUM SAS, particularly focusing on the GEN3 silicon-based anode materials used in 18650 batteries [1][2]. Battery Performance - At 900 cycles, the GEN3 silicon-based anode batteries deliver over 3,100 milliampere-hours (mAh) of capacity, retaining more than 80% of their initial capacity [2][9]. - In comparison, benchmark batteries made with high-grade artificial graphite provide about 2,400 Ampere-Hours (Ah) cumulative energy, while the GEN3 batteries achieve approximately 3,200 Ah, indicating a cumulative energy gain of over 30% [2][8]. Material Development - The results confirm NOVACIUM's capability to produce advanced silicon-based materials that integrate well with commercial battery formats, enhancing capacity and durability [3][9]. - The GEN3 batteries exhibit an average capacity of about 3,200 mAh, surpassing the graphite benchmark's 2,604 mAh by 21% [6][9]. Market Potential - The global graphite market is projected to grow from approximately 700,000 tonnes in 2021 to 4.5 million tonnes by 2030, creating an addressable market of 450,000 to 675,000 tonnes for silicon-based materials, valued between US$22.5 billion and US$33.8 billion [11][12]. - HPQ's strategy focuses on producing silicon-based materials for the 3C markets, currently valued at US$12 billion and expected to grow to US$38.3 billion by 2030 [12]. Future Developments - The next step involves establishing a pilot plant for manufacturing silicon-based materials, either independently or through partnerships with industrial players [13].
