At the 'InterBattery Awards 2026,' held as a side event of this year's 'InterBattery 2026,' new technologies that significantly enhance ultra-high energy density batteries, lithium iron phosphate (LFP), energy storage systems (ESS), and fire safety received numerous awards. Notably, this year's event saw a Chinese company win for the first time, drawing attention.
On March 3, the Korea Battery Industry Association hosted the 'InterBattery Awards 2026' ceremony at the Glad Hotel in Yeouido, Seoul, and presented awards to 12 companies with innovative technologies among the exhibitors participating in InterBattery 2026.
In the battery category, the award-winning products were LG Energy Solution’s 'JF2 DC Link 5.0 ESS for Power Grids,' SK On’s 'Prismatic On-Vent Cell,' Samsung SDI’s '700Wh/L High-Energy Prismatic Battery,' and Rumpleer’s 'Korean-Made LFP Battery.'
LG Energy Solution’s product is an ESS for power grids built with a highly chemically stable LFP-based composition and an all-in-one container structure. It was highly rated for strengthening ESS competitiveness for power infrastructure through high-performance insulation design that incorporates building energy-saving design standards.
SK On’s 'Prismatic On-Vent Cell' features an innovative structure that allows the vent position in prismatic batteries to be freely designed. It applies safety technology that releases gas in a controlled direction in the event of thermal runaway and improves battery system design flexibility.
Samsung SDI’s product is a next-generation battery that, for the first time among prismatic cells, achieves an ultra-high energy density of 700Wh/L and a maximum output of 4000W. It incorporates cutting-edge techniques such as minimizing component resistance and new material structures, as well as no thermal propagation technology.
The startup Rumpleer was highly praised for developing a domestically produced 'LFP prismatic battery' in a market dominated by large corporations, obtaining Korea’s first KC certification and presenting mass production potential.
In the materials category, the award went to EcoPro BM’s 'Supply Chain-Independent LFP Direct Synthesis Method,' LG Chem’s 'Thermal Runaway Delaying Thermoplastics,' Eco&Dream’s 'Next-Generation 90+ High-Nickel Precursor,' and Solum Advanced Materials’ 'ESAR 10-Micrometer (μm) Foil Stainless Technology.'
EcoPro BM’s technology synthesizes LFP cathode materials by directly using raw materials, excluding precursor processes that are highly dependent on China. It was highly rated for both simplifying processes and delivering higher performance than existing methods, thus achieving both supply chain stabilization and carbon reduction.
LG Chem won with a next-generation battery material that can withstand temperatures and pressures above 1,200℃ for over 10 minutes, effectively delaying flame and pressure propagation during battery thermal runaway and thereby improving system stability.
In the components category, FDC’s 'Explosion-Proof Vent for ESS' received the award. In the equipment category, Lead Intelligent Equipment’s (China) Dry Electrode Mixing and Coating System, Jarvis’s 'Ultra-Fast CT Inline Battery Inspection System,' and T-W’s 'Ultra-High-Speed Combined (Notching+Stacking) Equipment' were each recognized.
Lead Intelligent Equipment’s Dry Electrode Mixing and Coating System is a next-generation manufacturing system that implements a solvent-free dry electrode process. Through precise roll control and the industry’s first variable roll diameter uniform heating system, it enables the formation of high-quality electrodes. Compared to conventional wet processes, it reduces energy consumption and has also been recognized for its compatibility with large-scale production lines.
Yeongeun Sung, Professor at the College of Engineering at Seoul National University and chair of the InterBattery Awards 2026 judging panel, explained, "There was significant discussion within the judging panel about awarding a Chinese product, but we took into account the fact that a considerable number of Chinese companies participate in the exhibition and that domestic battery cell companies also acknowledge Lead Intelligent Equipment’s technological capabilities."
Jarvis’s Ultra-Fast CT Inline Battery Inspection System is an X-ray CT inspection device that improves both inspection speed and resolution by rotating the optical system while the battery remains stationary, capturing images of internal defects.
T-W’s equipment is an ultra-high-speed stacking machine capable of a 0.2-second cycle time per head. The structure and control system have been completely redesigned to maintain electrode position alignment and ensure quality stability even in high-speed repetitive operation environments.
'InterBattery Awards 2026,' now in its third year since launching in 2024, comprehensively evaluates and awards products and technologies of exhibiting companies for technological merit, innovation, and contribution to the industry.
This year, 42 innovative products and technologies from 25 companies were submitted, expanding the scale compared to the previous year (32 products from 24 companies). InterBattery 2026 will be held for three days at COEX Exhibition Center in Seoul starting March 11. During the exhibition, the award-winning products will be displayed at the 'InterBattery Awards Special Exhibition.'
Taeseong Park, Executive Vice Chairman of the Korea Battery Industry Association, stated, "InterBattery Awards 2026 is highly significant as it showcases innovative achievements in essential areas such as ultra-high energy density, safety technologies, ESS, self-reliance in LFP technology, and next-generation process technologies for cost innovation, all of which are crucial for the era of AI and robotics."
