Renewable Energy Semiconductor ManufacturingMassachusetts, United States51-200 Employees

Alsym Energy is a renewable energy semiconductor manufacturer based in Malden, Massachusetts, employing between 51 and 200 people. It develops sodium-ion battery technology for energy storage, including its Na-Series families of cells and modules. The Na-Series approach is described as non-flammable and designed to prevent thermal runaway at the chemistry level, enabling safer, scalable deployment for energy storage applications. The company has pursued strategic partnerships, such as a June 2026 collaboration with Re:Build Manufacturing LLC for sodium-ion battery production and a May 2026 letter of intent with ESS Tech to add 8.5 GWh of sodium-ion cells and modules, followed by an integration agreement announced in April 2026. In 2025, Alsym Energy launched the Na-Series and engaged in research collaborations, including a partnership with Rensselaer Polytechnic Institute to replace slurry-based lithium-ion electrode manufacturing with a solid-state cold spray method. From a financial standpoint, the company reports annual revenue in the range of $25 million to $50 million and has secured around $78 million in funding.
