Samsung SDI said Monday that it has been seeking collaboration with multiple robotics companies looking to use its all-solid-state batteries, which are under development and set for mass production starting next year. The statement fueled speculation that Samsung SDI’s all-solid-state batteries could be used to power Hyundai Motor’s Atlas humanoid robot, given the partnership between the battery manufacturer and the carmaker. “Thanks to the application of physical artificial intelligence technology, the robotics market has grown rapidly and demand for all-solid-state batteries is increasing, considering the limited space for batteries in such devices and the need for high safety and power,” Park Jong-sun, head of Samsung SDI’s battery strategic marketing office, said at a conference call on the company’s earnings during the fourth quarter of last year. Samsung SDI’s quarterly operating loss from its battery business reached 338.5 billion won ($231 million). Despite the disappointing

Samsung SDI said Friday its U.S. arm has won a battery supply contract without disclosing details, with the deal widely believed to be related to Tesla's energy storage system (ESS) business. The Korean battery maker said details of the agreement, including the amount, counterparty and period, are being kept confidential for business reasons and that it will withhold further disclosure until January 2030. The latest regulatory filing followed a separate announcement made in November 2025, in which Samsung SDI hinted it had been in talks to supply battery products to Tesla. The earlier filing came in response to a request from the Korea Exchange to explain media reports that the company plans to supply batteries for Tesla's ESS business worth 3 trillion won ($2.08 billion). "The demand for ESS is expanding significantly due to the sharp growth in the artificial intelligence industry," an industry watcher said. "It seems Samsung SDI is securing a series of agreements by demonstrating
