Alsym Energy, the leader in next-generation, flameless sodium-ion batteries, revealed insights into the physics-informed AI framework that drives its newly introduced Na-Series of batteries. The fusion of physics-based modeling and artificial intelligence with autonomous testing and molecular diagnostics creates a closed loop that allows Alsym Energy to dramatically reduce the development timeline of safer and affordable energy storage products.
Addressing the Li-ion Bottleneck
In the context of rising electricity consumption across the globe, the constraints posed by today’s lithium-ion batteries have turned out to be a crucial barrier towards achieving energy independence. This problem is most pronounced in big energy storage projects, as the high energy density and flammability issues associated with Li-ion batteries limit their deployment in certain settings due to permitting concerns.
Alsym’s AI platform brings a systematic approach that addresses these challenges faced across the industry in discovering novel battery chemistries:
Physics-Informed Search: Leverages AI to search through a large number of possibilities for chemistries and fast convergence on highly performing, flame-retardant chemistries.
Closed-Loop Experimentation: Combines machine learning with robotic experimentation to get maximum value from each experiment, overcoming the limitations of conventional trial and error techniques.

Detailed Battery Diagnostics: Provides insightful analysis into battery chemistry performance to optimize the performance of the battery from bench-scale all the way to mass production.
System-Level Co-Optimization: Simultaneously optimizes material, battery design, and process to ensure performance, safety, and cost-effectiveness at scale.
“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.”
Rapid Development and Proven Safety
The Na-Series represents the first major success of this innovation platform, moving from initial concept to a validated, high-performance prototype in under 12 months. Leveraging widely available, abundant materials, the Na-Series offers a resilient supply chain alternative to lithium-ion, coupled with superior safety credentials.
In rigorous testing-including accelerated rate calorimetry (ARC) and nail penetration trials-the Na-Series cells exhibited no signs of thermal runaway, rupture, or flame, even under extreme conditions. This inherent safety removes a major barrier to widespread deployment.
“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.”
