JNTG Highlights Flow Battery Electrode Portfolio at IFBF 2026

JNTG presented graphite felt, carbon cloth and carbon paper electrode solutions at the International Flow Battery Forum 2026 in Budapest, expanding its flow battery offerings. The company said its growing supply business in North America and mass-production capabilities are helping it target the fast-growing long-duration energy storage market.

Why it matters: - Flow batteries are gaining attention as a safer, longer-life alternative to lithium-ion batteries for long-duration energy storage. - JNTG’s expanded electrode portfolio positions the South Korea-based carbon materials company to compete in a growing ESS market. - The company’s supply relationships with major system manufacturers in the U.S. and Canada point to commercial traction beyond hydrogen fuel cells.

What happened: - JNTG participated in the International Flow Battery Forum 2026 in Budapest, Hungary, in June 2026. - The company attended as a Gold Sponsor. - JNTG hosted an exhibition booth and delivered a technical presentation on electrode activation technology and mass production experience. - JNTG showcased graphite felt, carbon cloth and carbon paper electrode solutions for flow batteries.

The details: - JNTG built its flow battery business on carbon-based energy materials and manufacturing capabilities developed through its gas diffusion layer business for hydrogen fuel cells. - The company developed and began mass production of graphite felt electrodes for flow batteries in 2023. - JNTG said the new electrode lineup is designed to meet different flow battery system requirements. - The International Flow Battery Forum is the world’s largest conference focused on the flow battery industry. - The event brings together experts to discuss technology developments and market trends. - Flow batteries are considered a next-generation energy storage technology for energy storage systems. - Compared with lithium-ion batteries, flow batteries offer lower fire risk and longer service life. - The company said the flow battery market is expanding rapidly as global ESS demand grows. - JNTG has begun supplying flow battery electrodes to major system manufacturers in the United States and Canada. - JNTG said that business has driven significant growth over the past three years.

Between the lines: - JNTG is trying to translate fuel-cell materials expertise into a broader energy-storage business. - The IFBF appearance gave JNTG a global platform to signal both technical credibility and manufacturing scale. - The move toward multiple electrode formats suggests JNTG is targeting a wider range of system designs, not a single customer segment.

What's next: - JNTG said it will keep developing customer-oriented products. - The company said it will continue to focus on stable, high-quality mass production. - JNTG is looking for additional business opportunities with global customers and industry partners.

The bottom line: - JNTG is using IFBF 2026 to pitch itself as a scaled supplier in the emerging flow battery supply chain, not just a materials developer.
