People have been waiting for Samsung to bring Silicon-Carbon (Si-C) anode batteries to Galaxy phones for a couple of years now, but the company hasn’t. Even the Galaxy S26 Ultra is expected to use a conventional Li-Ion battery. The South Korean firm has now made a Silicon-Carbon battery, but it is not for phones or any mobile device.
It is for electric vehicles.
Samsung SDI, Samsung Electronics’ battery manufacturing arm, has announced an alliance with KG Mobility to jointly develop battery pack technologies for electric vehicles. It uses Samsung SDI’s 46-series cylindrical cells with high-nickel NCA cathodes and proprietary silicon carbon nanocomposite anodes.
Samsung says its new technology reduces swelling and improves the overall lifespan of the battery. Moreover, its tabless design is claimed to offer reduced internal resistance and optimized current flow, resulting in enhanced power output and fast-charging performance. The company has also enhanced the thermal management process and used advanced manufacturing processes to improve battery reliability and safety compared to previous batteries.
These new battery packs will be used in KG Mobility’s next-generation electric cars. The two firms have signed a memorandum of understanding (MoU) to work on future battery technologies.
KG Mobility is a South Korean automobile brand founded 71 years ago (1954), and it was called Dong-A Motor back then. It was later renamed SsangYong Motor Company in 1988 after it was acquired by South Korea’s SsangYong Group. Then, it was acquired by Daewoo Motors (1997), then by the Chinese manufacturer SAIC Motor, and then by India’s Mahindra & Mahindra (2010). In 2022, it was acquired by South Korea’s KG Group.
Since Samsung MX (mobile phone division) uses batteries made by Samsung SDI in some models, it is possible that it could bring silicon-carbon anode battery technology to future Galaxy phones, but we can’t say for sure when that will happen.
