Solidion Technology, Inc. (NASDAQ:STI) is a developer and manufacturer of advanced solid-state battery solutions designed to meet the growing energy storage demands of electric vehicles, portable electronics, and grid-scale storage applications. Leveraging proprietary ceramic electrolyte formulations and patented manufacturing processes, the company focuses on delivering high-energy-density, long-life battery cells with enhanced safety characteristics compared to conventional lithium-ion alternatives. Solidion’s core activities encompass research and development, pilot-scale production, and licensing of its solid-state technology to strategic partners in the automotive and electronics sectors.
Founded in 2015 by Dr. Alice Chang and Dr. Mark Stevens, Solidion Technology began as a spin-out from the Massachusetts Institute of Technology’s Materials Science and Engineering department. Since its inception, the company has scaled its operations from a single R&D laboratory in Boston to a global footprint that includes engineering centers in Munich and Tokyo, as well as a pilot production facility in Seoul. Collaboration agreements with leading OEMs and specialty chemical firms have enabled Solidion to refine its electrolyte compositions, optimize electrode interfaces, and accelerate cell prototyping toward commercialization.
Solidion’s product portfolio consists of multilayer solid-state cells in cylindrical, prismatic, and pouch formats, along with modular battery packs for electric buses, consumer electronics, and backup power systems. In addition to its hardware offerings, the company provides turnkey design services, cell testing, and lifetime modelling to support customer-specific performance requirements. Solidion’s technology roadmap targets energy densities exceeding 400 watt-hours per kilogram and cycle lives beyond 2,000 full-depth-of-discharge cycles, positioning the company at the forefront of next-generation energy storage innovators.
Under the leadership of President and Chief Executive Officer Dr. Alice Chang, alongside Chief Technology Officer Dr. Mark Stevens and Chief Financial Officer Michael Ruiz, Solidion Technology continues to expand its manufacturing capacity and strategic alliances. The executive team’s combined expertise in materials science, scale-up engineering, and financial management has driven key milestones, including the completion of a $50 million Series C funding round in 2022. With ongoing investments in R&D and global partnerships, Solidion aims to achieve commercial launch of its first mass-market solid-state battery cells by 2025.
