Company Description
SES AI Corporation (NYSE: SES) is a battery technology company focused on the development and manufacturing of AI‑enhanced high‑performance lithium‑metal (Li‑Metal) and lithium‑ion (Li‑ion) batteries. According to its public disclosures, SES AI positions its technology to power electric transportation on land and in the air, and to support energy storage and other battery‑intensive applications.
SES AI describes itself as the first battery company to accelerate its pace of innovation by using superintelligent AI across its business. This AI is applied to research and development, materials sourcing, cell design, engineering and manufacturing, and battery health and safety monitoring. The company states that it is an Li‑Metal battery developer and manufacturer founded in 2012 and headquartered in Boston, Massachusetts, with operations in Singapore, Shanghai, and Seoul.
Core business and technology focus
Based on its press releases, SES AI develops and manufactures Li‑Metal and Li‑ion batteries aimed at electric vehicles (EVs), drones, urban air mobility (UAM) and eVTOL aircraft, robotics, energy storage systems (ESS), and other uses that require high energy density and power. The company highlights that its batteries are supported by AI‑driven tools for materials discovery and battery management.
SES AI reports that it operates a factory in Chungju, South Korea, established in 2021 with support from South Korea’s central government, Chungcheongbuk‑do province and the City of Chungju. This facility is described as producing a 100Ah lithium‑metal battery for automotive applications and a 30Ah lithium‑metal battery for UAM applications. The Chungju plant supports manufacturing for drone applications and is referenced in the company’s plans to expand cell manufacturing capacity for drones and UAM.
Molecular Universe software platform
A distinctive element of SES AI’s business is its Molecular Universe platform, which the company describes as a software and services platform for battery material discovery. SES AI states that Molecular Universe uses AI and large molecular databases to help discover and optimize electrolyte materials for different battery chemistries and applications.
In its public communications, SES AI notes that Molecular Universe has been used with enterprise customers to discover electrolyte materials for:
- Low‑to‑medium content silicon anode Li‑ion electrolyte for EV applications
- High content silicon anode Li‑ion electrolyte for drones and robotics
- Li‑Metal electrolyte for drones and eVTOL applications
- Lithium iron phosphate (LFP) Li‑ion electrolyte for ESS applications
The company also describes versions of Molecular Universe (such as MU‑1 and MU‑1.5) as offering capabilities for literature research and solution recommendation, molecule and formulation search, and prediction of cell performance. SES AI reports that it offers Molecular Universe through subscription tiers and joint development arrangements, and that it has generated revenue from this platform.
Materials and supply chain initiatives
SES AI’s disclosures highlight efforts to connect its AI‑driven discoveries with commercial materials supply. The company has signed a term sheet to establish a joint venture with Hisun New Energy Materials Ltd. Co., a Texas‑based electrolyte contract manufacturer, to commercially supply electrolyte materials discovered by Molecular Universe. SES AI states that this proposed joint venture is intended to produce and supply these electrolytes on a commercial scale and to represent a new source of recurring revenue by supplying discovered materials to customers globally.
In addition, SES AI has announced a collaboration with Top Material, a Korea‑based advanced materials and gigafactory engineering company, to boost SES AI’s cell manufacturing capacity in Chungju for drone and UAM applications and to support compliance with applicable U.S. National Defense Authorization Act (NDAA) country‑of‑origin and supply chain requirements for its drone customers.
Energy storage systems and UZ Energy acquisition
SES AI has expanded into the energy storage systems (ESS) market through the acquisition of Shenzhen UZ Energy Co., Ltd. The company describes UZ Energy as a leader in premium ESS hardware with an existing customer base in Australia, Europe and Asia. SES AI states that, with this acquisition, it is entering the multi‑hundred GWh ESS market by integrating cells, modules, packs and AI‑enabled safety and health systems.
According to SES AI, combining UZ Energy’s ESS hardware with SES AI’s software is intended to create integrated ESS offerings that use materials and monitoring capabilities informed by Molecular Universe. The company has also referenced the potential to expand UZ Energy’s business and to integrate it into SES AI’s broader battery and software strategy.
