Alsym Energy Inc
About
Alsym Energy develops non-flammable sodium-ion batteries for stationary energy storage, sold as the Na-Series to data centers, utilities, mines and commercial buildings.
The cells use an NFPP+ cathode chemistry that Alsym says cannot enter thermal runaway, so systems run from -40 to 60°C on passive cooling alone. It rates them for 15,000 cycles over a 20-year life.
The company is based in Malden, Massachusetts, where its team covers research, testing, cell and module design and AI-driven materials development. In June 2026 it signed a memorandum of understanding with Re:Build Manufacturing to develop commercial-scale cell production at Re:Build's plant in New Kensington, Pennsylvania.
