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 has announced that its affiliate Company based in Lyon, France, NOVACIUM SAS (“Novacium”) has acquired a family of patents related to the surface treatment of carbon base materials from Dr. Alexander Zaderko.
Dr. Zaderko is a globally recognized researcher from the University of Kyiv in Ukraine with more than 20 years of experience in carbon functionalization for a wide range of applications, including energy and supercapacitors.
Silicon-based anodes have up to 10 times the energy density of a graphite-based anode, which is why Porsche, Mercedes and GM are betting on silicon-anode batteries.
While silicon-based anode materials show significant potential for batteries, they are known to suffer from significant degradation during charging and discharging cycles. To address this issue, a common approach is the application of a carbon coating. This carbon coating is widely used to mitigate some of the degradation, improving the overall performance and durability of silicon-based anodes.
In collaboration with Dr. Zaderko, Novacium’s team of researchers have adapted and validated the substantial potential of Novacium surface treatments for carbon-based materials in battery applications.
Initial tests have shown significant performance improvements in silicon-based Li-ion batteries. These results indicate that the new surface treatment has a dual effect on battery properties: it reduces degradation by improving the interface with the electrolyte, enhancing cyclability (battery lifespan), and also reduces charging time.
Moreover, initial test results with graphite anode materials alone (without silicon) suggest that the new surface treatment positively impacts the performance of graphite-based Li-ion batteries by enhancing the graphite-electrolyte interface.
“Our innovative approach aims to significantly improve the operation of lithium batteries,” commented Mr. Oleksiy NICHIPORUK, Novacium’s Chief Technical Officer (“CTO”). “We believe that the application of Novacium’s patented surface treatments has the potential to transform and enhance the performance of Li-ion batteries, benefiting not only silicon-based anode materials but the entire battery market.”
