According to Autoblog, what happens is that the first Spark EV battery packs were made by a company that went bust: A123 Systems. When that happened, GM put another supplier to take care of them. It was LG Chem, which we now call LG Energy Solution.
GM told Autoblog that the stock of battery packs made by A123 Systems had run out, making the company close that part number.
