POSCO Group has begun construction of a solid electrolyte factory, a core material of the 'all-solid-state battery' hailed as the future of electric vehicle batteries, aiming to secure a leading position in the next-generation battery market.

On the 14th, POSCO held a groundbreaking ceremony for the factory in Yangsan-si, Gyeongsangnam-do. The ceremony was attended by Lee Kyung-seop, Head of Secondary Battery Materials Business, and Kim Tae-heung, CEO of POSCO JK Solid Solution, among others.

All-solid-state batteries are next-generation batteries that replace the liquid electrolyte and separator?two of the four main materials of lithium-ion batteries, which include cathode, anode, electrolyte, and separator?with solid-state ion-conductive materials. The market is expected to grow significantly starting from 2030. Since they do not use highly flammable liquid electrolytes, the risk of explosion is reduced, greatly enhancing safety. Additionally, the use of high-energy-density cathode and anode materials enables a revolutionary increase in electric vehicle driving range.

POSCO Group declared its transformation into a leading eco-friendly future materials company with the launch of its holding company, POSCO Holdings. The secondary battery materials business is one of the group's seven core businesses. Along with expanding cathode and anode production capacity, the group plans to develop materials for all-solid-state batteries to secure a leading position in the next-generation battery materials market.
