OCSiAl, the world’s leading manufacturer of single wall carbon nanotubes, has been approved as an official supplier by Molicel, a global leader in high-performance lithium-ion battery cells.
The two companies have formed a long-term strategic partnership focused on significantly enhancing ultra-high-power lithium-ion cells. OCSiAl supplies Molicel with nanotubes to improve both anode and cathode performance, resulting in batteries with superior efficiency, fast-charge convenience, and extended cycle life compared to existing market solutions.
Last year, Molicel showcased the innovative technology and design of ultrahigh-power P50B lithium-ion battery cells, enhanced with OCSiAl’s single wall carbon nanotubes. The next-generation INR-21700-P50B power cell boasts ultra-high energy density, 260 Wh/kg, and delivers unbeatable peak power of 413 W at 45°C, along with 5C ultrafast charging capabilities. The INR-21700-P50B is designed to cater to the premium segment in various applications, holding great potential for hyper EVs, racing sports cars, eVTOLs, racing motorcycles, heavy lift drones, and more. To boost battery performance, the long-term partnership will focus its research on three-dimensional conductive networks, resilient framework electrodes, and Si-dominated anodes.
“The collaboration between Molicel’s advanced cell technology and OCSiAl’s single wall carbon nanotubes has made it possible for the INR-21700-P50B to redefine high-power cylindrical cells,” said Casey Shiue, President of Molicel. “This synergistic approach yields a superior power-to-energy ratio, a remarkable doubling of battery cycle life to 1,400 cycles at 100 W discharge, and ultralow impedance through innovative interface engineering, resulting in superior performance and efficiency, while maintaining excellent energy density and cycle life.”
OCSiAl single wall carbon nanotubes, nature’s longest and most flexible material for conductivity and reinforcement of electrodes, hold a superior position among other carbon-based additives for batteries.
“OCSiAl single wall carbon nanotubes create robust long-distance electrical networks that connect particles of active materials, forming ‘high-speed highways’ capable of withstanding high currents and remaining stable even during severe active material volume expansion over long-term cycling,” said Andrej Seniut, Head of OCSiAl Energy Projects.
OCSiAl is committed to establishing a sustainable global supply network as a cornerstone for future battery technologies. Following the launch of its nanotube synthesis and dispersion facility in Europe last year, OCSiAl continues to actively invest in production expansion across key markets to meet the rapidly growing demand for high-performance
batteries.
