Solid-state batteries are widely regarded as the next frontier in EV technology, offering significant advantages over traditional lithium-ion batteries. By replacing liquid electrolytes with solid ones, these batteries promise longer range, faster charging, enhanced safety, and improved durability. SK On claims its pouch cell format, already a strength, is ideally suited for integrating solid-state technology. Park Kisoo emphasized that this design could be a “weapon” to outmaneuver Chinese firms, which currently lead in semi-solid-state batteries—a hybrid technology bridging lithium-ion and full solid-state systems. While semi-solid-state batteries, using gel-like electrolytes, are already in Chinese EVs like the MG4 and IM L6, SK On aims to leapfrog to all-solid-state solutions for greater performance.
Scaling Up in the U.S.
SK On’s ambitions are backed by a massive manufacturing footprint in the United States. The company operates two battery plants in Georgia and, through its BlueOval SK joint venture with Ford, is building three additional factories in Tennessee and Kentucky. These facilities, supported by a historic $9.6 billion loan from the U.S. Department of Energy, aim to bolster domestic EV battery production. The investment not only strengthens SK On’s supply chain for clients like Ford and Volkswagen but also supports its research into advanced technologies like immersion cooling for thermal management. This technology enhances battery efficiency for EVs, AI data centers, and energy storage systems, positioning SK On as a versatile player in the clean energy sector.
Facing Fierce Competition
China’s battery giants, such as CATL and BYD, currently hold a lead in semi-solid-state technology, with vehicles like the MG4 offering 333 miles of range at a budget-friendly price of $11,000 to $16,500. Western automakers, including Mercedes-Benz, BMW, and Stellantis, are also advancing, with prototypes like the BMW i7 and Dodge Charger Daytona testing solid-state packs. SK On’s timeline targets solid-state battery development by 2027 and mass production by 2029, a schedule that aligns with competitors like Nissan and Toyota but aims to capitalize on its pouch cell expertise. The global race is tight, with Chinese firms benefiting from lower costs and established supply chains, while SK On leverages partnerships with U.S. and European automakers to close the gap.
Broader Industry Applications
SK On’s innovations extend beyond EVs. The company is exploring applications for its battery technology in AI data centers and energy storage systems, where efficient thermal management is critical. Its immersion cooling technology, already in discussions with Ford and Hyundai, could improve performance in high-demand environments. As EV demand faces challenges with the looming end of U.S. tax credits in September 2025, Park remains optimistic, predicting a global sales rebound by late 2027 if automakers can narrow the price gap between EVs and gas-powered vehicles. SK On’s diversified approach ensures it remains competitive across multiple sectors, even as the EV market fluctuates.
Why It Matters for Consumers
For tech users and EV buyers, SK On’s push toward solid-state batteries could mean more affordable, longer-range, and safer electric vehicles by the end of the decade. A mass-market EV with a 500-mile range and rapid charging could transform road trips and daily commutes, addressing common concerns about range anxiety and charging infrastructure. However, with Chinese manufacturers already deploying semi-solid-state batteries in budget EVs, SK On’s success hinges on delivering cost-competitive solutions. For now, consumers can expect incremental improvements in lithium-ion batteries, with SK On and others enhancing energy density and charging speeds to make EVs more practical in the interim.
