SES AI (NYSE: SES) is powering a new era of electric transportation with the world’s most advanced Li-Metal battery. Backed by our proprietary AI algorithm to actively monitor battery health and safety, SES’s large-format Li-Metal cells are a lighter, longer-range, and smarter alternative to traditional Li-ion batteries. SES is the only Li-Metal battery company to enter into three major joint development agreements with the world’s largest automotive companies, General Motors, Honda, and Hyundai. Based in Boston, SES AI is led by founder and CEO, Dr. Qichao Hu.

SES Boston Global HQ

Material chemistry (human and deep-learning) R&D, electrolyte foundry, project management

SES AI’s global headquarters is in Woburn, Massachusetts, just outside Boston where SES had its origins in Lab 4-061 in the basement of building 4 at MIT. Today, SES AI’s Woburn office serves as the heartbeat of its R&D innovation in high-performance Li-Metal rechargeable batteries for EVs and eVTOLS.

SES Shanghai

Manufacturing processes, cell/module/BMS R&D, JDA

Completed in 2023, SES Shanghai Giga is a 300,000 square-foot facility located in the “auto city” Jiading, Shanghai, capable of pilot-scale production of Li-Metal batteries and critical materials, by far the largest Li-Metal facility on the planet.

SES South Korea

Urban Air Mobility initiatives, JDA, pilot plant
SES AI’s newest facility is in Chungju, South Korea. Equipped with expanded in-house manufacturing capability, the new facility further enhances SES AI’s global cell engineering capability, serving as a strong complement to SES AI’s Shanghai facility in the steady production of large-format 50Ah and 100Ah Li-Metal cells. In addition to EV, SES Korea also supports several Urban Air Mobility initiatives, which are part of South Korea’s national strategy.
