sk innovation lithium battery factory (Korea)

SK innovation was established in 1962. Its predecessor, Korea Petroleum Corporation, was the first oil refining company in South Korea. Currently, SKI is the largest petrochemical group in South Korea. The largest shareholder, SK Co., Ltd., holds 33.4%. In 2012, the company achieved sales of 68.46 billion US dollars. Its main subsidiaries include SK Energy, SK Chemicals, SK Lubricants, Incheon Petrochemical, SKME and SKM&C.

Power lithium battery technology

The positive electrode material of SKI power battery adopts NCM ternary material, the energy density of the battery cell reaches 180wh/kg, and the energy density of the battery pack is about 110Wh/Kg.

SKI has the core technology of power lithium battery separator. It is not only the third manufacturer in the world to develop lithium battery separator, but also has the low shrinkage and high heat-resistant patented technology of separator manufacturing. Electric vehicles have been put into use.

Power lithium battery customers

SK Innovation actively promotes the R&D and production of battery systems for electric vehicles, and has become the battery for Mitsubishi Fuso, Mercedes-Benz, and Hyundai-Kia Group under the German Daimler Group. supplier, and set up a joint venture with China BAIC Group to provide battery support for BAIC's new energy models.

In 2013, SK Innovation and Continental of Germany established a joint venture, SK Continental E-motion, with SK Innovation to supply batteries and Continental to supply BMS. It plans to build a 3GW-scale battery production capacity and actively explore the global electric vehicle battery market. In addition, SKI is a power lithium battery supplier for Hyundai-Kia and Daimler, but it has not yet achieved mass supply.

Layout of power lithium battery industrialization bas

SKI began to develop lithium-ion batteries in 1996, and successively built lithium-ion polymer battery production lines to produce consumer electronics batteries and power batteries.

At present, the SKI production base is mainly concentrated in South Korea, the Daejeon base is responsible for the basic development of batteries, the production line of cells and battery packs; the Cheongju and Zengping bases are responsible for the production of separators.

The SKI power battery base is located in Seosan, South Korea. Construction started in 2011 and initial production in 2012. At present, the Ruishan battery factory has production lines for electrodes, cells, and battery modules, with an annual production capacity of 800WMh electrodes and 200WMh battery cell assembly, which can supply battery packs for 10,000 pure electric vehicles. In addition, based on market demand, the factory has the ability to increase the existing capacity by 5 times to 1000 MWh in the short term. In addition, SKI also plans to increase the production capacity of the Seosan base to 3,000MWh in 2020, with the goal of providing batteries for 150,000 pure electric vehicles.

The power lithium battery industry base built in Beijing Yizhuang Economic Development Zone in 2014 will achieve a production capacity of 100,000 unit battery packs after being put into operation, forming the power lithium battery industry layout in Beijing, China and Ruishan, South Korea.

SK Innovation invested US$1.7 billion to build a new automotive power battery production plant in Georgia, USA

According to reports, the plant will be put into use in batches and is expected to be fully operational by 2025, when its annual production capacity will be able to meet the battery needs of 250,000 electric vehicles.

SK said the plant will initially supply batteries for Volkswagen electric vehicles built in Chattanooga. The plant will have a production capacity of 10 gigawatts, a measurement that represents the total electricity production from batteries expected to be produced each year.

"Volkswagen is doing business in Tennessee; Alabama is home to companies like Daimler (Mercedes-Benz parent company) and Hyundai," SK Innovation President and CEO Jun Kim said on Monday. "South Carolina The state also has facilities for Daimler, Volvo and BMW; Georgia also has Kia Motors. Further north, there are big automakers like Ford. This is where demand is concentrated.”
