Alsym Energy
About
Alsym Energy is a Malden-based battery company developing non-flammable sodium-ion cells for stationary energy storage. Its flagship Na-Series cells are made from earth-abundant sodium and iron, eliminate thermal runaway and work without the active cooling that lithium iron phosphate systems need. They are built for heavy cycling and long life, handle millisecond power transients and large swings, and pair with gas turbines and renewables, making them a fit for AI data centers, utilities, commercial real estate and defense.
The company argues that lithium-ion batteries are held back by fire risk, costly heating and cooling systems and supply chains concentrated in countries of concern. Its alternative uses low-cost inputs from a supply chain of US and free-trade partners, and a wider operating temperature range lowers cooling costs. Alsym also uses a proprietary, physics-informed AI platform to discover new materials and chemistries about ten times faster than trial-and-error methods.
