Posco Holdings Accelerates Investment... Collaborates with All-Solid-State Battery Company 'Prologium'

POSCO Holdings has decided to collaborate with Taiwanese solid-state battery specialist ‘ProLogium’ to develop core materials for next-generation secondary batteries.

On the 12th, POSCO Holdings invested in ProLogium and agreed to jointly develop key materials including solid-state battery-specific cathode materials, silicon anode materials, and solid electrolytes. Based on this, they plan to establish a global supply chain with ProLogium. POSCO Holdings and ProLogium have agreed not to disclose the investment amount or shareholding ratio.

Founded in 2006, ProLogium developed solid-state batteries in 2012 and has been strengthening collaborations with global automakers and secondary battery companies. It has attracted investments from global investors and is jointly developing solid-state batteries for electric vehicles with major automakers such as Germany’s Daimler Group. It also sells solid-state batteries to small IT device manufacturers, including smartwatches.

Lee Kyung-seop, Executive Director and Head of the Secondary Battery Materials Business Promotion Group at POSCO Holdings, said, "Through cooperation with ProLogium, we will strengthen POSCO Group’s competitiveness in next-generation secondary battery materials and further expand our business portfolio." Vincent Yang, Chairman of ProLogium, said, "POSCO Group, which operates not only raw materials for secondary battery materials such as lithium, nickel, and graphite but also cathode and anode material businesses, is the most ideal partner. We expect this collaboration to accelerate the production plans for solid-state batteries and contribute to the stable supply of essential materials."

Solid-state batteries are considered next-generation batteries. They replace the liquid electrolyte between the battery’s cathode and anode with a solid electrolyte and eliminate the separator, ensuring safety and increasing energy density.

Meanwhile, POSCO Holdings has secured material development capabilities such as high-capacity cathode materials and silicon anode materials applicable to solid-state batteries. Earlier this year, it established POSCO JK Solid Solution, a solid electrolyte production corporation, to strengthen its capabilities in developing next-generation secondary battery materials.
