Taking the lead in future energy development
SK innovation has led Korea's energy industry for the past 50 years through ceaseless innovation and technology development and has secured global technology leadership in new energy.
SK innovation has successfully applied high energy density ternary materials to lithium-ion batteries for the first time in the electric vehicle battery industry for mass production. Based on such technological capabilities, SK innovation signed supply contracts with major global automakers, Hyundai Motor Group, BAIC Group and including Daimler AG has been expanding the electric vehicle battery business.
SK innovation started the development of lithium-ion batteries for hybrid electric vehicles in 2005 and their production in 2006. In 2010, SK innovation was selected as a battery provider for Hyundai's BlueOn, Korea's first electric vehicle, and Kia's Ray. In February 2011, SK innovation was designated to supply batteries to SLS AMG E-Cell, the first electric supercar of Mercedes-AMG, the high performance automobile division of Daimler AG. As such, SK innovation has been widely recognized by major global automakers for its technological prowess.
Started developing lithium-ion batteries for electric vehicles
Started developing batteries for electric vehicles
Built the first assembly line in Seosan
SK innovation established joint ventures with BAIC Group and Beijing Electronics Holding and, since 2013, has been supplying batteries to electric taxis and private and public electric vehicles in Beijing where the demand for electric vehicles are on the rise. Since 2014, SK innovation has been a battery supplier for Soul EV, Kia's electric vehicle made for the global market. In early 2016, SK innovation won a large-scale contract to supply batteries to main models of Daimler AG, which has proven again its technology and production capabilities.
Established BESK in December
Built the second assembly line in Seosan in January
Expanded the first and second assembly lines in Seosan in July
Built the third assembly line in Seosan
Starting with the 100MW battery assembly line in SK innovation Global Technology in Daejeon, We completed a battery production system by adding a 200MW battery assembly line in Seosan, Chungcheongnam-do Province, in September 2012. In order to meet the increasing demand for electric vehicle batteries in 2014 and 2015, we expanded the assembly lines in Seosan, securing a capacity of producing batteries for 30,000 electric vehicles per year. In 2016, we set-up a new assembly line to respond to the rapidly growing customer needs. In 2017, SK Innovation will be constructing a new manufacturing building in Seosan for full-scale volume expansion.
SK innovation is fitted with the entire value chain for mid/large-sized battery production from electrodes and separators
(that are essential in batteries) to battery cells and packs.
SK innovation is producing high-quality, high-strength wet separators that are applied to lithium-ion batteries,
enabling batteries to be highly stable and heat-resistant as well as long-lasting.
High-quality Wet Separators
Applying thick ceramic coating to thin PE material to enable thinner film formation, high strength, excellent stability, and heat resistance
Heated at 160℃ for 1 hr, at which PE material shrinks and melts
Compared to prismatic and cylindrical cells, pouch battery cells allow for lighter and thinner cell fabrication, and design flexibility fit for different capacities and space requirements for different vehicle models.
SK innovation was the first in the industry to apply high energy density material to large-size lithium-ion batteries and succeed in its mass production.
SK innovation plans to reinforce relationships with current customers, including Daimler AG, BAIC Group, and Hyundai Motor Group, while seeking new business opportunities with other global automakers for further penetration into the global electric vehicle battery market.
