- After 100 cycles, 18650 batteries with GEN3 silicon-based materials still outperform commercially available graphite batteries by approximately 40%, GEN1 by over 26%, and GEN2 by over 15%, all with minimal noticeable degradation [1].
MONTREAL, Sept. 03, 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 new battery milestones achieved by its France-based affiliate, NOVACIUM SAS ("Novacium").
This update highlights the positive trend observed after 100 charge-discharge cycles in the latest tests of Lithium-ion 18650 batteries, made with a blend of graphite and Novacium’s GEN3 silicon-based anode material. The charge-discharge tests [2], which simulate real-world usage to assess durability and longevity, confirm a 40% overall capacity improvement compared to the graphite benchmark.
Additionally, after 100 cycles, the battery performance is 26% higher than the previous GEN1 material and 15% higher than the GEN2 material, with minimal degradation compared to the graphite benchmark, at less than 0.5%.
“These results confirm our position as a top-tier producer of advanced silicon anode material,” said Dr. Jed Kraiem, COO of Novacium. “The ability to producing silicon-based anode material that enables 18650 battery cells to exceed 4,000 mAh under maximum discharge testing conditions, as highlighted in the July 30th, 2024, release, and achieve 40% more capacity than graphite-only Li-Ion batteries after 100 charge-discharge cycles under real-world conditions demonstrate our capabilities and expertise in the domain.”
Enhancing Battery Performance with Silicon-Based Anode Materials
Graph 1) Average capacity, in milliampere-hours (mAh), of 100% graphite, GEN1 & GEN2 batteries over 150 cycle testing [1]
(the blue, orange and green lines). Average capacity of GEN3 batteries over 100 charge-discharge cycle testing [1] (the yellow line).
Graph 1 illustrates the battery capacity, in mAh, of batteries made with Novacium GEN3 materials over the first 100 cycles, (yellow line) compared to those made with GEN2 and GEN1 materials, as well as 100% graphite benchmark batteries (green, orange and blue lines) over 150 cycles.
Using the data from Graph 1, we observe that at 100 cycles, the average capacity of three 18650 batteries made with Novacium GEN3 materials remains at a very respectable 3,838 mAh. In comparison, the average capacities are 3,332 mAh for three batteries made with Novacium GEN2 materials, 3,040 mAh for three batteries made with GEN1 materials, and 2,758 mAh for three 100% graphite benchmark batteries.
Therefore, after 100 cycles, GEN3 silicon-based batteries continues to demonstrate an overall capacity improvement of approximately 40% compared to the graphite benchmark, 26% compared to GEN1 material, and 15% compared to GEN2 material.
Silicon-Based Anode Materials with graphite-like degradation at 100 cycles
Graph 2) the blue line shows the relative capacity of 100% graphite batteries, the orange line the relative capacity of GEN1 batteries, and the green line
the relative capacity of GEN 2 batteries, over 150 cycles [1]. While the yellow line shows the relative capacity of GEN 3 batteries over 100 cycles [1].
Graph 2 shows that the performance degradation for GEN3 advanced silicon material over 100 cycles is minimal, with a retention of 98.8% compared to 99.2% for the graphite benchmark. This difference of less than 0.5% is very minimal and falls within the margin of error.
Using the results from the 100-cycle tests shown in Graph 2, we observe that the relative capacity of 18650 batteries made with Novacium GEN3 materials (yellow line) is 98.8%, decreasing from 3,883.0 mAh to 3,838.2 mAh. In comparison, the relative capacity of the batteries made with Novacium GEN2 materials (green line) is 98.3%, decreasing from 3,370.1 mAh to 3,332.4 mAh, while the relative capacity of those made with GEN1 materials (orange line) is 97.7%, decreasing from 3,145.5 mAh to 3,040.2 mAh. Finally, the relative capacity of the 18650 batteries made with 100% graphite (blue line) is 99.2%, decreasing from 2,780.0 mAh to 2,758.5 mAh.
"Our material integrates seamlessly into existing manufacturing processes, allowing manufacturers to adopt these cutting-edge batteries anode materials without the need for costly retooling or overhauls," said Bernard Tourillon, President and CEO of HPQ Silicon Inc. and NOVACIUM SAS. "These advancements not only streamline production but also accelerate the widespread adoption of high-performance silicon-based batteries, setting a new standard in the industry."
