South Korean battery giants face Chinese competition, eye innovation to stay ahead

Leading battery and materials manufacturers in South Korea voiced their concerns about the rising competition from Chinese rivals in the battery market. However, they also expressed confidence in maintaining their leadership positions in both high-nickel and lithium iron phosphate (LFP) battery markets.

China's influence in the rechargeable battery market is growing, particularly in the LFP battery segment, as electric vehicle manufacturers increasingly adopt these cost-effective batteries to produce more affordable vehicles.

LG Energy Solution Co.'s Chief Technology Officer, Shin Youngjoon, noted during a panel discussion at The Korea Investment Week hosted by The Korea Economic Daily that, "Excluding the Chinese market, LG Energy Solution ranks first in the global electric vehicle battery market, but the gap is narrowing very quickly." However, he added, "Nevertheless, there are enough cards to maintain our lead."

South Korean battery manufacturers are now entering the LFP battery market, which has been dominated by Chinese companies. This move is in response to growing demand. Shin explained, "If we decide to do it, there is absolutely no reason for Korea to fall behind." LG-made LFP batteries are currently under verification by an EV company for potential use in vehicles to be released in 2026.

POSCO Future M Co and EcoPro Co have plans to begin producing LFP cathodes as early as 2025. POSCO Future M CEO Kim Jun-hyung pointed out that Korean companies supplying LFP cathode materials to the US could benefit from a 27% tariff exemption under the Korea-US Free Trade Agreement, maintaining price competitiveness over Chinese products.

In the high-performance ternary battery segment, Korea continues to lead in both technology and price competitiveness. As Chinese battery companies seek to enter the European market, their demand for high nickel is increasing.

Regarding solid-state batteries, the companies did not provide specific details about their development plans but acknowledged the challenges of achieving mass production and marketability. LG aims to mass-produce semi-solid batteries from 2026 and solid-state batteries from 2030.

To improve production yields, reduce costs, and maintain product quality globally, the three companies are enhancing the role of domestic factories as "mother factories." LG Energy Solution is also considering adopting a dry process for battery production, which can reduce manufacturing costs and increase energy density compared to the wet process.

Kang Kisuk, a professor at Seoul National University, highlighted China's dominance in terms of valid patents for "next-generation lithium-ion batteries." He emphasised the importance of developing new high-nickel cathode materials, transitioning from graphite to silicon as an anode material, and eventually exploring lithium metal as an anode material, as graphite is currently dominated by the Chinese supply chain.
