Last year, the company signed a deal with U.S.-based Flatiron Energy Development to supply LFP batteries for energy storage systems.Show MoreShow LessSK On said it also plans to expand its partnership with NeoVolta Power through a separate agreement later this year, under which it would provide an additional 9 GWh of LFP battery cells. NeoVolta would assemble them into battery packs using its packaging expertise.The planned partnership would bring the total volume of cooperation between the two companies to 18 GWh.SK On had set a target of securing more than 20 GWh of global energy storage system orders this year and has said it was in talks with several U.S. customers over additional supply contracts totaling more than 10 GWh.Other South Korean battery makers, including LG Energy Solution and Samsung SDI, have also been repurposing EV battery production lines to make batteries for energy storage systems as U.S. subsidies for EVs are phased out.Energy storage batteries use similar chemistry to automotive batteries and store electricity for facilities such as data centres, helping balance power demand and supply.($1 = 1,377.6700 won)Source: ReutersNewsletterWeek in ReviewSubscribe to our Chief Editor’s Week in ReviewOur chief editor shares analysis and picks of the week's biggest news every Saturday.Sign up for our newslettersGet our pick of top stories and thought-provoking articles in your inboxSubscribe hereGet the CNA appStay updated with notifications for breaking news and our best storiesDownload hereGet WhatsApp alertsJoin our channel for the top reads for the day on your preferred chat appJoin hereAlso worth readingContent is loading...Expand to read the full storyGet bite-sized news via a newcards interface.
