The joint venture of OCI and POSCO Future M completed the construction of a plant to produce high-softening-point pitch, a core material for anode materials of rechargeable batteries
The joint venture of OCI and POSCO Future M completed the construction of a plant to produce high-softening-point pitch,a core material for anode materials of rechargeable batteries.  - Joint venture P&O Chemical completed the construction of its high-softening-point pitch plant with an annual capacity of 15,000 tons in Gongju, Chungcheongnam-do on November 13.- High-softening-point pitch is essential in enhancing battery charging and discharging efficiency and boosting battery life.- This first domestic production of the material, which had been entirely imported, is expected to stabilize supply and promote technological independence. - OCI continues to focus on key materials for semiconductors and rechargeable batteries P&O Chemical, a joint venture of OCI Holdings (President Jin Sug Suh) and POSCO Future M (President Kim Jun-hyung) held a ceremony to celebrate the completion of a plant for high-softening-point pitch in Gongju-si, Chungcheongnam-do on November 13, and announced Korea’s first mass production.  The ceremony was attended by OCI President Yoo Shin Kim, POSCO Future M President Kim Jun-hyung, P&O Chemical President Jong Kook Kim, business executives, and regional representatives including Gongju-si Mayor Choe Won-cheol. The high-softening-point pitch plant was built in an area of 32,500 square meters in the Tancheon Industrial Complex, Gongju-si, Chungcheongnam-do with an investment of KRW 96.3 billion. With annual production capacity of 15,000 tons, the plant will mass produce the core material used for the anodes of batteries for the first time in Korea.  Pitch is carbon material produced by refining coal or petroleum, and the raw material of high-softening-point pitch used for anode materials is a petroleum substance. One of the characteristics of high-softening-point pitch is that it begins to soften at a higher temperature than ordinary pitches. High-softening-point pitch is a key material for battery anode materials and has a significant impact on the quality of batteries.  It is largely used as a material for coating the surface of an anode, and plays an essential role in enhancing the charging and discharging efficiency of batteries and extending battery life.  Because the domestic market for anode materials was not large, all high-softening-point pitch was imported from China and Germany. However, with the steady growth of the EV battery market, demand for high-softening-point pitch is rising rapidly.  With the new plant, P&O Chemical is expected to make significant contribution to the technological independence of rechargeable battery materials by realizing the localized production of high-softening-point pitch, a core material for anode materials. The domestic production of high-softening-point pitch would not have been possible without OCI’s solid technology that has been accumulated for decades. OCI, a major subsidiary of OCI Holdings, was the first company in the world to succeed in the commercialization of liquid pitch in 1996. OCI is Korea’s only company to produce pitch, with an annual capacity of 520,000 tons. OCI also developed high-softening-point pitch with its proprietary technology in its efforts to broaden its product portfolio from liquid pitch based on steel byproducts to high-softening-point pitch derived from petroleum substances and to expand its profit base. Meanwhile, based on its robust technology, OCI has diversified its business portfolio to include high value-added core materials for semiconductors and rechargeable batteries. Last June, OCI signed an MOU with Tokuyama Corporation of Japan to establish a joint venture to produce semiconductor-grade polysilicon with an annual capacity of 11,000 tons, and in July signed a long-term contract with Nexeon to supply special materials for the anode materials of rechargeable batteries for five years from 2025.  P&O Chemical is a joint venture established in July 2020 by OCI Holdings and POSCO Future M with the aim to strengthen competitiveness in high valued-added materials. The joint venture is currently owned by OCI Holdings (49%) and POSCO Future M (51%), respectively. OCI Holdings plans to transfer its stake in P&O Chemical to OCI through investment in kind to maximize synergy.  Prior to this high-softening-point pitch plant, P&O Chemical built a plant to produce high-purity hydrogen peroxide, a key material used in semiconductor fabrication, with an annual capacity of 50,000 tons in Gwangyang, Jeollanam-do in October 2022. P&O Chemical envisions continuously enhancing its competitive edge based on OCI’s superior technology and business expertise combined with the competitive raw materials of POSCO Future M. OCI President Yoo Shin Kim said at the ceremony, “With the successful mass production of high-softening-point pitch following high-purity hydrogen peroxide, P&O Chemical has taken a step forward as a key enterprise in high-tech materials in Korea. With OCI’s technology and stable product quality and active cooperation with POSCO Future M, we will grow P&O Chemical as one of the leading suppliers of core materials in the world.”

OCI signs a long-term agreement to supply raw material for silicon anode material for lithium-ion batteries
OCI signs a long-term agreement to supplyraw material for silicon anode material for lithium-ion batteries. - OCI will supply core raw material for silicon anode materials to Nexeon Ltd. (UK) for five years from 2025.- OCI will start commercial production from 2025 after groundbreaking this year for a plant to produce a special raw material for silicon anode materials with an annual capacity of 1,000 tons.On July 26, OCI announced that it signed a long-term agreement with Nexeon to supply a core raw material necessary to produce silicon anode materials for rechargeable batteries. Under the agreement, OCI will supply to Nexeon a special raw material (SiH4) for silicon anode materials for five years from 2025. This initial long-term supply agreement is valued at about KRW 70 billion (USD 55 million), and the size of the agreement is expected to increase as the customer expands production.The plant to produce special raw material for silicon anodes will have an annual capacity of 1,000 tons and will be built in the lot of OCI’s Gunsan Plant, which produces polysilicon for semiconductors and phosphoric acid. The construction of the plant will start this year, with commercial production slated to begin in the first half of 2025, and the production volume will be adjusted depending on the demand of Nexeon. Nexeon is a leading manufacturer of silicon anode materials for rechargeable batteries with more than 170 patents related to silicon-based anode materials. The UK company recently signed a long-term agreement to supply silicon anode materials to Panasonic, the world’s fourth largest battery cell manufacturer, and will secure production capacity under the agreement.  Demand for silicon-based anode material is rising as a next-generation battery material as it addresses the shortcomings of conventional graphite-based anode materials and offers longer driving distance with a shorter charging time. However, due to price and stability issues, few firms have succeeded in commercializing the technology. In addition, first-generation anode materials such as silicon oxide cannot replace more than 10% of graphite due to its expansion characteristic. Nexeon’s silicon-rich anode material is a second-generation battery material that overcomes the hurdles of the first-generation material using its proprietary technology to relieve the expansion of silicon anode material. It is reported that by increasing the amount of Nexeon’s second-generation anode materials incrementally when making cells, the energy density of rechargeable batteries can be enhanced by up to 50%. As a result, electric vehicles equipped with Nexeon’s silicon anode materials can have longer driving distances and shorter charging times, as well as stability. Demand for Nexeon’s second-generation silicon anode material is expected to grow rapidly, as it can replace most of the first-generation silicon materials.OCI can supply raw material for the second-generation silicon anode material directly to Nexeon’s plant through pipes, and will increase production capacity in tandem with market growth and rising customer demand. The raw material for silicon-based anode materials to be produced by OCI will be cost competitive because it is produced in the process of manufacturing polysilicon for semiconductors at the Gunsan Plant. In terms of production facilities, OCI will introduce the latest simplified manufacturing process and a one-step shutdown valve for a quick response in the event of safety problems to ensure efficiency and stability in production. Starting with this supply of raw material for silicon anode materials, OCI will actively develop raw materials for next-generation silicon anode materials and semiconductors to establish its leadership in raw materials for rechargeable batteries and semiconductors. On June 1, OCI announced that it signed an MOU to establish a joint venture with Tokuyama Corporation of Japan to produce polysilicon for semiconductors with a capacity of 11,000 tons. The company will also produce high-softening-point pitch, a coating material for anodes, with POSCO Future M from the fourth quarter this year. OCI seeks to expand the production of semiconductor materials such as phosphoric acid, hydrogen peroxide, and precursor. OCI President Yoo-Shin Kim said, “We expect to produce price-competitive quality products by maximizing the strength of OCI as a cutting-edge material supplier and the advantage of Nexeon’s advanced silicon anode material technology. OCI will continue to expand investment to sharpen its competitive edge and build leadership in the rapidly growing rechargeable battery materials market.”
