To mark the domestic launch of the Cadillac luxury electric vehicle ‘Lyriq,’ which extensively utilizes POSCO Group’s secondary battery materials and steel products, POSCO Group and GM hosted a joint promotional event.
On July 26, both companies displayed the ‘Lyriq’ at the POSCO Center in Gangnam, Seoul, offering test drives and purchase consultations to POSCO Group employees and nearby professionals.
The event was attended by Yoo Byeong-og, President of POSCO Future M; Seo Yu-ran, Head of POSCO’s Automotive Materials Marketing Division; Hector Villarreal, President of GM Korea; and Tommy Hosea, Vice President of GM’s Global Operations Purchasing and Supply Chain. It commemorated the launch of this electric vehicle, a product of the collaboration between POSCO Group and GM.
The Lyriq, the first model based on GM’s next-generation modular electric vehicle platform ‘Ultium,’ is also the first electric vehicle to fully integrate both anode and cathode materials from POSCO Future M. It features a battery pack comprising 12 modules, each containing battery cells made from POSCO Future M’s anode and cathode materials.
The Lyriq’s battery uses high-nickel NCMA* cathode materials, known for high energy density, enabling a driving range of up to 465 km on a full charge. POSCO Future M successfully mass-produced NCMA single-crystal cathode materials domestically for the first time in March last year. The anode material employs low-expansion natural graphite anodes, which improve high-speed charging performance, stability, and lifespan compared to conventional products. The Lyriq supports DC fast charging with up to 190 kW output, allowing approximately 120 km of range with a 10-minute charge.
The Lyriq also incorporates POSCO’s ultra-high-strength steel and electrical steel products. Its body and chassis use Giga Steel (tensile strength over 980 MPa) and ultra-high-strength steel, earning the highest safety rating of 5 stars from the National Highway Traffic Safety Administration (NHTSA) in the U.S., enhancing strength, workability, and environmental friendliness.
The drive motor features high-efficiency, non-oriented electrical steel* ‘Hyper NO,’ reducing energy loss and delivering top-tier driving performance among its peers. POSCO is the sole domestic producer of high-efficiency, non-oriented electrical steel, a material requiring advanced technology, with only a few global steelmakers, including POSCO, capable of providing stable quality.
