Producer
Samsung SDI Co., Ltd.
Samsung SDI Co., Ltd. (Yongin, Gyeonggi-do, South Korea; KRX: 006400; ~KRW 20T revenue) is the battery manufacturing arm of the Samsung Group, producing cylindrical, prismatic, and pouch lithium-ion cells for consumer electronics (smartphones, laptops, tablets), power tools, and electric vehicles. In the consumer electronics LCO cell segment, Samsung SDI holds approximately 15-18% global market share. Samsung SDI manufactures LCO pouch cells at its Tianjin, China facility (primarily for smartphone applications) and cylindrical cells at Cheonan, South Korea. Samsung SDI is a co-supplier of Apple iPhone battery cells alongside ATL — Apple's dual-sourcing strategy for iPhones is the most sophisticated single-input procurement program in consumer electronics. Samsung SDI's EV battery business (NMC prismatic cells for BMW iX, Rivian, Stellantis) is growing faster than its consumer electronics segment.

USKokomo, Howard County, Indiana, USA · manufacturing_plant
Samsung SDI / Stellantis StarPlus Energy JV at Kokomo Indiana; two plants totaling 67 GWh capacity announced. Samsung SDI also building JV with GM in Indiana. Kokomo Indiana is an automotive manufacturing hub (Chrysler/Stellantis legacy). IRA Section 45X production credits make US cells economically competitive.
Samsung SDI Cheonan Cylindrical Cell Plant (South Korea) →
KRSouth Chungcheong · manufacturing
Samsung SDI's Cheonan, South Chungcheong Province, South Korea manufacturing facility produces cylindrical lithium-ion cells — primarily 18650 and 21700 format — for laptop computers and power tools. Consumer LCO cylindrical cells (for laptop batteries) are produced here alongside NCA/NMC cells for EV packs. Cheonan is one of Samsung SDI's two Korean cell manufacturing sites (the other is Ulsan for prismatic EV cells). Source: https://www.samsungsdi.com/about-sdi/global-network/detail.do
Samsung SDI Tianjin LCO Pouch Cell Plant (China) →
CNTianjin · manufacturing
Samsung SDI's Tianjin, China manufacturing facility produces LCO pouch cells for smartphone and consumer electronics applications. Tianjin is Samsung SDI's primary Chinese manufacturing base for consumer cell formats. The facility supplies Samsung Galaxy smartphone batteries and contributes to Samsung SDI's Apple co-supply arrangement. Samsung SDI Tianjin also produces some prismatic cells for energy storage adjacent to the consumer cell lines. Source: https://www.samsungsdi.com/about-sdi/global-network/detail.do

Did you know2024
Samsung SDI is tracked in EV battery supply chain analysis for its automotive cell business (BMW, Stellantis, Rivian), but the same cylindrical cell platform (18650, 21700) also powers the professional power tool market — Dewalt, Milwaukee Tool, and Bosch power tools depend on Samsung SDI cylindrical cells. Power tool manufacturers and EV manufacturers are competing for the same Samsung SDI cylindrical cell capacity from the same factories. A production allocation decision at Samsung SDI's Hungary Göd factory simultaneously affects European EV delivery timelines AND the availability of high-end cordless tools at Home Depot — two supply chains that analysts never model as sharing production capacity.
Samsung SDI ↗Origin2023
Samsung SDI was founded in 1970 as Samsung Sanyo Electronics, manufacturing CRT (cathode ray tube) display components for televisions. The "SDI" acronym stood for Samsung Display Industry as it expanded into flat panel display technologies in the 1990s. When LCD technology made CRTs obsolete in the 2000s, Samsung SDI pivoted its manufacturing infrastructure from display materials to lithium-ion batteries — applying similar precision chemistry expertise to a different energy storage problem. The company has been producing commercial Li-ion cells since 2000 and now makes batteries for BMW iX, Stellantis EVs, and Rivian vehicles from its factories in South Korea, Hungary, and the United States.
