At 'Interbattery 2025,' the three major domestic battery companies (LG Energy Solution, Samsung SDI, and SK On) showcased their next-generation technologies, while this year, major Chinese companies also participated, intensifying the competition. With Chinese battery manufacturers aggressively targeting the market, domestic companies are emphasizing differentiation strategies, creating a tense atmosphere.

The event, held on the 6th at COEX in Gangnam, Seoul, saw the participation of powerful Chinese battery companies BYD and EVE Energy for the first time, drawing the attention of attendees. While their booths were relatively less crowded compared to those of major domestic companies, it was observed that Chinese tourists and other visitors were consistently visiting in small groups of two or three.

Although the booths of both companies were small in scale, they prominently showcased their flagship product, LFP (Lithium Iron Phosphate) batteries, and introduced their technological capabilities. BYD displayed batteries for electric bicycles and electric motorcycles as its main exhibition items, but did not showcase batteries for electric vehicles separately.

BYD explained that its LFP batteries are known for their high stability, long lifespan, and high output. Additionally, the company highlighted its capabilities in battery cell production, BMS (Battery Management System), and pack design, stating that it provides an end-to-end solution based on a vertical integration strategy.

EVE also set up its booth near BYD's to showcase its LFP battery technology. In addition, the company displayed LMFP (Lithium Manganese Iron Phosphate) and solid-state batteries, introducing a diverse range of products.

Notably, EVE's booth was located right next to LG Chem's, creating a natural atmosphere of comparison. While the number of visitors was lower than at LG Chem's booth, EVE demonstrated its determination to accelerate its efforts in targeting the global market.

In response, domestic battery companies emphasized battery safety and technological capabilities to highlight their differentiation from Chinese competitors. LG Energy Solution presented its cylindrical 46-series batteries along with BMTS (Battery Management Total Solution). Samsung SDI showcased ultra-high output 50A cylindrical batteries and solid-state batteries to emphasize the strengths of next-generation technologies. SK On also garnered attention with its high-voltage, mid-nickel batteries, which enhanced stability and reduced costs to align with changing market trends.

On the 5th, the opening day of the exhibition, the leaders of each company gathered to express their confidence in competing with China despite the challenging industry conditions.

Kim Dong-myung, CEO of LG Energy Solution, highlighted intellectual property (IP) as a key competitive advantage in the race against Chinese competitors. He stated, "LG Energy Solution will secure a competitive edge over Chinese companies by leveraging technologies such as the 46-series battery, lithium iron phosphate (LFP) battery, and Cell-to-Pack (CTP) technology."

Meanwhile, 79 Chinese companies participated in 'Interbattery 2025.' This is a significant increase from 24 companies in 2023 and 62 companies in 2024, showing a steady upward trend in participation.
