Alsym Energy, a pioneer in non-flammable, high-performance sodium-ion batteries, today announced details of the proprietary physics-informed AI platform used to develop the company’s recently launched Na-Series sodium-ion batteries. By integrating fundamental physics models with AI, autonomous testing and proprietary molecular diagnostics in a closed-loop system, Alsym is accelerating the design of safer, inexpensive, commercialized batteries through all phases of the development cycle.
As global demand for electricity surges, the limitations of lithium-ion batteries have become increasingly apparent, particularly around safety and supply chain constraints. Lithium-ion chemistry presents inherent challenges, including flammability and reliance on constrained global supply chains—issues that become more acute in large-scale energy storage, where higher energy densities considerably increase fire risks, and growing demand across sectors further strains the supply chain and imperils energy sovereignty.
At the same time, the pace of innovation must accelerate because existing battery solutions are not designed to meet the cost, safety, and performance required for today’s infrastructure demands, particularly in urban areas. Permitting restrictions due to fire risks and long delays are the top concerns for energy storage system project developers.
Alsym’s physics-informed AI platform is designed to accelerate battery innovation by fundamentally improving how new chemistries are discovered, developed, and scaled:
- Uses physics-guided AI to narrow an otherwise unmanageable range of possible battery chemistries — rapidly converges on deployable, non-flammable, high-performance battery chemistries rather than exploring candidates in isolation.
- Integrates machine learning with automated, closed-loop experimentation to extract maximum actionable learning from each test, accelerating progress across materials, cell design, and operating conditions beyond traditional trial-and-error approaches.
- Applies continuous electrochemical, materials, and molecular diagnostics and feedback to understand not just how a battery performs, but why—enabling targeted optimization and robust, predictable scaling from lab to prototype to pilot and commercial production.
- Drives AI-optimized system-level end-to-end co-design of materials, cell architecture, and manufacturing processes – ensuring performance, safety, cost and manufacturability are achieved simultaneously at scale.
This innovation platform approach underpins the development of Alsym’s Na-Series and positions the company to rapidly deliver continued innovation as it scales.
The rapid development of Alsym’s Na-Series sodium-ion battery utilized a chemistry that was identified, tested, developed and built in under a year. Na-Series batteries are non-flammable while delivering high performance, affordability, and competitive energy density. By leveraging abundant, widely available materials, the technology also provides a secure and resilient supply chain advantage over conventional lithium-ion solutions.
“The energy transition cannot wait decades for a better answer for energy storage,” said Dr. Kripa Varanasi, Professor of Engineering at MIT and co-founder of Alsym Energy. “What’s required is a fundamentally faster way to turn innovation into infrastructure. The challenge is no longer just discovery – it’s deployment. By integrating physics-informed AI, deep electrochemical expertise, and system-level intelligence across cell architecture, operations and manufacturing, we’ve built a platform that enables continuous innovation and scalable deployment of safer, cost-effective battery technologies for critical infrastructure.”
Na-Series batteries surpass non-flammability tests
From the outset, Alsym set a clear objective: to develop a truly non-flammable and high-performance battery chemistry. The physics-informed AI platform enabled this goal—guiding the discovery and refinement of a system that eliminates the risk of thermal runaway.
Alsym has validated the inherent safety of its chemistry through rigorous testing. In accelerated rate calorimetry (ARC) testing, Na-Series cells were heated from room temperature to 400°C without ever going into thermal runaway. In nail penetration tests conducted on fully charged cells, no rupture, fire, or flame was observed at any point—demonstrating the system’s resistance to catastrophic failure modes that have challenged existing battery technologies. These results underscore the success of Alsym’s platform to deliver real innovation designed to solve a market problem.
“The safety of Na-Series enables deployments everywhere lithium-ion batteries can, and all the places lithium can’t,” said Mukesh Chatter, CEO of Alsym Energy. “The levelized cost of energy (LCOE) advantages are also clear: its wide operating temperature range enables substantial operating cost savings, and upfront costs are very competitive both at the cell and system level. Coupled with fast charge and discharge rates, and flexible use across short, medium and long durations, Alsym Na-Series is a fundamentally better battery for energy storage. For customers, this means lower total cost of ownership, reduced risk, simplified safety and thermal management requirements, broader deployment flexibility, and increased revenue through fast charge–discharge and optimized cycling that captures value from dynamic grid pricing.”
Alsym’s Na-Series batteries support a wide range of applications, including utilities and microgrids, data centers, commercial real estate, industrial operations, maritime environments, defense systems, and residential energy storage. The company is currently advancing its commercialization roadmap and will be shipping cells and modules to strategic partners starting in Q3 2026.
