Ford Motor Co. will partner with LG Energy Solution Ltd. to build a new battery plant in Turkey, dropping a deal with SK On Co., as the US carmaker seeks to speed up the shift to clean cars and diversify its battery suppliers, people familiar with the matter said. Ford and LG Energy Solution plan to sign a memorandum of understanding within the coming weeks, probably in late January or early February, according to two people with knowledge of the matter who asked not to be named because the change in partners isn’t public.
