South Korea’s battery industry is navigating a period of rapid transformation, marked by political shifts abroad and technological innovation at home. On April 12, 2026, Hungary’s parliamentary elections brought an end to Prime Minister Viktor Orban’s 16-year rule, as the opposition Tisa Party, led by Peter Marzar, secured a sweeping victory with 138 out of 199 seats. This historic political upheaval, reported by major international outlets, has sent ripples of uncertainty through the global battery supply chain—particularly for Korean manufacturers who have invested heavily in Hungary’s burgeoning battery sector.
Hungary, under Orban’s administration, had positioned itself as a premier hub for battery manufacturing in Europe. The government’s 'National Battery Industry Strategy 2030,' unveiled in 2022, offered generous subsidies and tax incentives to attract multinational battery companies. According to the Korean Financial News, this strategy dovetailed with the European Union’s Industrial Acceleration Act (IAA), which incentivizes automakers to source at least 70% of electric vehicle parts within the EU to qualify for subsidies. As a result, Korean giants like Samsung SDI, SK On, and EcoPro BM established major production bases in Hungary to strengthen their foothold in the European market.
EcoPro BM, in particular, completed a state-of-the-art cathode factory in Debrecen in November 2025. The facility boasts an annual production capacity of 54,000 tons, with plans to double that figure through future expansion. The company had counted on this site to solidify its European supply chain and meet the growing demand for battery materials in the region. "Factory production is proceeding without disruption," EcoPro BM stated on April 16, 2026, but added that it is "closely monitoring the evolving political situation."
However, the incoming administration in Hungary has signaled a starkly different approach to industrial policy. Peter Marzar and the Tisa Party have been openly critical of the previous government’s battery-friendly stance, citing concerns over environmental pollution and labor safety. Marzar’s campaign promises included a comprehensive review of existing subsidies, a re-examination of factory permits, and the establishment of new regulatory agencies focused on environmental and labor oversight. He has been particularly vocal about hazardous material handling at Samsung SDI’s Hungarian plant and has visited battery factories in Göd and Iváncsa to underscore his commitment to stricter regulation.
While Marzar and the Tisa Party have yet to comment directly on EcoPro BM’s Debrecen facility, the heightened scrutiny of major Korean battery makers has introduced a new layer of risk for these companies. As one industry insider told the Korean Financial News, "It’s only natural that overseas investments are sensitive to local government policies. The fulfillment of the new ruling party’s campaign pledges will inevitably impact the strategies and benefits for domestic battery and secondary cell material companies operating in Hungary."
Back in Seoul, Korean battery material producers are not standing still. At the Next Generation Battery Conference (NGBS) held on April 16, 2026, leading firms unveiled strategies to adapt to both shifting market dynamics and tightening global regulations. Isu Specialty Chemical announced it is on track to begin production of 150 tons per year of lithium sulfide (Li2S)—a key raw material for solid-state batteries—by June 2026. The company’s vice president, Ha Jong-wook, highlighted the advantages of their internalized supply chain and expertise in safely handling hydrogen sulfide (H2S), a toxic byproduct. "Our strength lies in our long history of safely managing hydrogen sulfide and putting it to meaningful use in our products," Ha said, as reported by SisaON.
Isu Specialty Chemical’s approach leverages byproducts from its parent company, Isu Chemical, which produces normal paraffin (NP). This integration allows the company to secure raw materials efficiently and maintain cost competitiveness. Ha noted, "In case the byproduct hydrogen sulfide is insufficient, we are also introducing processes to produce hydrogen sulfide directly." The company’s continuous production process, he added, ensures both cost advantages and consistent product quality. Looking ahead, Isu Specialty Chemical plans to expand its annual production capacity to 500 tons and is investing in research for lithium sulfide applications in lithium-sulfur cathodes, aiming to boost battery energy density.
EcoPro BM, meanwhile, is racing to diversify its product portfolio and strengthen its global supply chain. The company is expanding beyond its traditional NCA (nickel-cobalt-aluminum) cathode materials to include high voltage mid-nickel (HVM), lithium manganese rich (LMR), lithium iron phosphate (LFP), and sodium-ion batteries. "There’s a perception that EcoPro BM only makes NCA, but we’ve been preparing to broaden our lineup for three to four years," said Oh Dong-gu, executive director at EcoPro BM, during his NGBS presentation. He revealed that mass production of NCM (nickel-cobalt-manganese) cathode materials is slated to begin by the end of 2026.
The technical roadmap is ambitious. For HVM, EcoPro BM is pushing to raise battery voltage from the current 4.3-4.4V to 4.5V, aiming to lower costs and extend battery life compared to high-nickel alternatives. LMR development focuses on reducing nickel content below 40% and increasing manganese, though managing gas generation remains a challenge. Oh explained, "The key is how to control gas emissions when using more manganese. We’re improving this through in-house cell validation and collaboration with OEMs." Sodium-ion battery development is also underway, with Oh expressing confidence: "China may have commercialized it first, but our performance is on par or better, thanks to our focus on doping and coating techniques."
EcoPro BM’s Ochang plant operates a 4,000-ton pilot line for LFP cathode materials, with third-generation products already in production. Samples are being supplied to customers, and full-scale deliveries are available for those ready to adopt the new technology. Internationally, EcoPro BM is investing in a nickel refining and precursor plant in Indonesia, expected to commence operations in 2027, further reinforcing its global supply chain resilience.
In response to increasing regulatory demands in Europe and elsewhere for localized production and recycling, EcoPro BM has implemented a closed-loop recycling system in partnership with affiliates EcoPro CnG and EcoPro Innovation. Since 2020, this system has converted waste batteries and production scrap into black powder, from which lithium is extracted and processed into lithium hydroxide—eventually feeding back into cathode material production. Oh acknowledged that the early stage of electric vehicle adoption means waste battery supply remains limited, and competition from China for scrap materials is fierce. "We believe the market will grow as more cell manufacturers’ production losses become available, but for now, China is aggressively securing these resources at high prices. How we respond to this will be crucial," he said.
As the battery industry stands at a crossroads—caught between geopolitical shifts in Hungary and the relentless pace of innovation in Korea—companies like EcoPro BM and Isu Specialty Chemical are demonstrating both agility and resolve. Their efforts to diversify portfolios, secure supply chains, and adapt to new regulatory landscapes underscore the high stakes and global scale of the competition for battery supremacy.
For Korean battery makers, the coming years will demand careful navigation of both political and technological currents. The outcome will shape not only their own fortunes but also the future of electric mobility across continents.
