- 18650 batteries with GEN3 silicon-based materials continue to deliver 3,734 mAh of capacity after 200 cycles [1], surpassing the MuRata high-performance US18650VTC6 battery by 25% compared to its advertised starting capacity of 3,000 mAh, and by 66% compared to its capacity at 200 cycles [2]
MONTREAL, Sept. 18, 2024 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company specializing in green engineering of silica and silicon-based materials, is pleased to update shareholders on the latest battery milestones achieved by its France-based affiliate, NOVACIUM SAS (“Novacium”).
Recent charge-discharge tests at the 200-cycle mark for Lithium-ion 18650 batteries, made with a blend of graphite and Novacium’s GEN3 silicon-based anode material, revealed a 36% capacity improvement with only 2% degradation compared to graphite benchmarks. The remaining capacity of 3,734 mAh exceeds the starting capacities of leading 18650 battery models, which range from 3,000 mAh (+25%) [2] to 3,450 mAh (+8%) [3]. After 200 cycles, the GEN3 battery outperforms top models by 25% [3] to 66% [2].
“I’m thrilled with the overall result that our GEN3 silicon-based anode material consistently outperforms commercial benchmarks under very rigorous testing protocols [4],” said Dr. Jed Kraiem, COO of Novacium. “The observed 36% capacity improvement and minimal degradation over 200 cycles underscore the material's potential to enhance energy density and extend the operational lifespan of lithium-ion batteries, positioning it as a breakthrough in battery technology.”
Enhancing Battery Performance with Silicon-Based Anode Materials
Graph 1) Average capacity, in milliampere-hours (mAh), of 100% graphite, GEN1, GEN2 & GEN3 batteries over 200 cycle testing [1] (the blue, orange, green and yellow lines).
Graph 1 illustrates the battery capacity (in mAh) of 18650 batteries made with Novacium's GEN3 (yellow line), GEN2 (green line), GEN1 (orange line), and a 100% graphite benchmark (blue line) over 200 cycles. At the 200-cycle mark, GEN3 batteries maintain an average capacity of 3,734 mAh, outperforming the graphite benchmark at 2,756 mAh. In contrast, both GEN2 at 2,694 mAh and GEN1 at 2,421 mAh perform worse than the graphite benchmark. This data indicates that GEN3 silicon-based batteries offer approximately 36% more capacity than the graphite benchmark, 54% more than GEN1, and 39% more than GEN2 after 200 cycles.
Silicon-Based Anode Materials with graphite-like degradation curb at 200 cycles
Graph 2) The blue line shows the relative capacity of 100% graphite batteries, the orange line the relative capacity of GEN1 batteries, the green line the relative capacity of GEN 2 batteries and the yellow line shows the relative capacity of GEN 3 batteries over 200 cycles [1]
Graph 2 demonstrates the minimal performance degradation for GEN3 advanced silicon material over 200 cycles, with a capacity retention of 96.2% compared to 98.6% for the graphite benchmark— a difference of 2.4%. Specifically, the absolute capacity of the GEN3 batteries (yellow line) decreased from 3,883 mAh to 3,734 mAh. In comparison, GEN2 batteries (green line) retained 79.6% of its capacity, dropping from 3,370 mAh to 2,694 mAh, while GEN1 batteries (orange line) retained only 77.0% of its capacity, decreasing from 3,145 mAh to 2,421 mAh. The graphite benchmark (blue line) showed a slight decline from 2,780 mAh to 2,756 mAh, retaining 98.6% capacity.
Graph 2 further illustrates that between 150 and 200 cycles, batteries using the graphite benchmark experienced a 0.2% degradation in capacity (from 98.8% to 98.6%), while batteries made with Novacium GEN3 materials showed a 1.6 % degradation (from 97.8% to 96.2%), a result that is comparable to graphite degradation. By comparison, batteries made with Novacium GEN2 materials experienced a 16.7% degradation (from 96.3% to 79.6%), while those made with GEN1 materials showed a 15 % degradation (from 92.5 % to 77.0%).
“I am also very excited by the fact that our partially optimized GEN3 material is able to reduce the observed degradation past 170 cycles compared to our GEN1 and GEN2 materials,” added Dr Kraiem.
“These results at 200 cycles place our silicon-based anode material technology in an enviable position, demonstrating real-world potential to significantly improve the performance of 18650 and 21700 batteries, a market expected to reach US $25 billion by 2026 [5],” said Bernard Tourillon, President and CEO of HPQ Silicon Inc. and NOVACIUM SAS. “This could position HPQ and NOVACIUM as key players in delivering next-generation energy solutions that meet both performance and sustainability targets for the industry.”
