MALDEN, Mass.–(BUSINESS WIRE)–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.

With this partnership, we believe Alsym is well-positioned to drive a more sustainable future around the world.” --- ## Alsym Energy: Protect Your Battery-Powered Tech Investments This Winter URL: https://www.alsym.com/alsym-energy-protect-your-battery-powered-tech-investments-this-winter/ Cold weather can diminish performance in expensive lithium-ion batteries and even lead to permanent damage Alsym™ Energy, a leading developer of non-lithium rechargeable battery technology, has issued a list of practical tips for consumers to protect their electric vehicles (EVs), lawn equipment, and other products that use expensive lithium-ion batteries as cold weather sets in across North America. While these devices have fewer reliability issues and are cleaner to operate than their gas-powered counterparts, sub-freezing temperatures can trigger chemical reactions inside lithium-ion batteries that reduce overall health and longevity, as well as increase the risk of battery failures and resulting fires. “Despite their increased presence in back yards and driveways, lithium-ion batteries experience reduced performance in relatively common winter conditions. In fact, storing and charging them in sub-zero temperatures may even cause damage that can lead to fires in spring and summer months,” said Alsym co-founder and CEO Mukesh Chatter. “As advocates for a new generation of non-flammable, non-toxic rechargeable battery technologies, we consider it our duty to help consumers protect their investments in expensive current-generation lithium-ion devices as well as help minimize potential risks to life and property.” Alsym’s five lithium-ion battery tips for consumers this winter: Park EVs in garages to prevent exposure to the lowest temperatures. While lithium-ion batteries can discharge at temperatures as low as -5 F / -20 C, performance is significantly reduced below 32 F / 0 C. Charging them in sub-freezing conditions can even result in permanent damage and increased risk of failure. Unless the manufacturer has advised against doing so due to a known safety issue or recall, parking your EV inside during winter is the easiest way to protect your investment and ensure peak performance. Allow cold EV batteries to warm up before using them. Before driving in cold weather, EV owners should warm their car’s interior to the battery’s optimum temperature. You can do this while plugged in to avoid draining the battery. This process is often referred to as “preheating” your vehicle, most cars can do this autonomously or on a pre-set schedule. Batteries discharge the most energy when they’re in their ideal temperature range, which means you’ll get more miles out of each charge. Preheating is also important for battery life, as cold weather puts extra strain on the battery. If you repeatedly drive with a cold battery, you should expect reduced performance in all conditions. Store batteries for lawn equipment inside if possible and top them off regularly. Like EVs, lithium-ion batteries used in electric leaf blowers, lawn mowers and power tools can also be damaged by cold temperatures. But unlike EVs, most of these devices use removeable batteries that can be safely stored indoors—as long as they’re not neglected. Lithium-ion batteries can be damaged if fully discharged for more than a short time, and a good rule of thumb is to recharge them when they get below 25% capacity. If you can’t take a battery inside, monitor its state of charge every 1-2 weeks. While new lithium-ion batteries only lose 3% – 5% of charge per month under ideal operating conditions, that rate increases as the mercury drops—especially for older batteries. If you own battery-powered devices that can’t go inside and don’t see use in the winter, set a reminder to top them up regularly. Disconnect chargers after the charging cycle is complete. It’s not always possible to spot a battery with internal damage, and risk of failure and fire is always highest when batteries are charging. Most rechargeable batteries should be disconnected as soon as possible after reaching a full charge to avoid a potential overcharging situation. As always, reference the manual that came with your EV, lawn equipment or other battery-powered products and follow the recommendations provided. --- ## Alsym Energy Announces Industry’s First High-Performance, Non-Flammable Battery Storage Option Suitable for Warm Climates URL: https://www.alsym.com/alsym-energy-announces-industrys-first-high-performance-non-flammable-battery-storage-option-suitable-for-warm-climates/ Announcement comes ahead of CEO’s scheduled talk at the FII7 conference in Riyadh Alsym™ Energy, a leading developer of non-lithium rechargeable battery technology, announced that it has successfully developed the industry’s first high-performance, non-flammable battery storage technology suitable for warmer climates. Climates with abundant sun or wind are ideally suited to renewable energy production. This presents a generational opportunity to bring new, diverse industries to the Middle East; however, expensive, fire-prone battery technologies are serious impediments to ambitious plans for rapid growth. With system-level capacities like lithium-ion and the ability to operate at elevated temperatures common to the region, Alsym batteries are safe to use in any environment. Alsym batteries also cost less than lithium-ion and require less cooling equipment, significantly increasing system efficiency and lowering both acquisition and operating costs. “The Alsym team has developed an entirely new battery technology that’s ideally suited to the needs of a rapidly changing climate. This is the kind of innovative thinking that will help accelerate the pace of global decarbonization,” said Alsym advisor Dr. Peter H. Diamandis, Founder and Executive Chairman of the XPRIZE Foundation. “Low-cost renewable energy, paired with non-flammable storage, will substantially help countries around the world reduce greenhouse gas emissions and spur new interest from power-intensive industries such as automotive, aerospace, green hydrogen, chemicals, and metals.” “When it comes to lithium-ion batteries, the level of fire risk increases as the mercury rises,” said Alsym CEO & Co-Founder Mukesh Chatter. “Recent battery storage fires in Australia, France, and the United States have required evacuations and shelter-in-place orders, and some cities are considering significant restrictions and even bans. We need to be looking beyond lithium-ion if we’re going to safely and responsibly deploy the amount of battery storage necessary to make a full transition to renewables.” The announcement comes as Mr. Chatter prepares to deliver remarks at the 7th Edition of the Future Investment Initiative Institute’s upcoming flagship conference in Riyadh, Saudi Arabia (FII7). Mr. Chatter, whose presentation is entitled “Renaissance in Renewables: Fact or Fiction,” will deliver his remarks on Day 1 of FII7, at 3 p.m. on October 24, on the Open Stage. First organized in 2017 by the FII Institute, a global nonprofit foundation with an investment arm that seeks to turn ideas into real-world solutions, the FII7 conference will be held October 24-26 in Riyadh, Saudi Arabia.

Establishing the Inter-Agency Fire Safety Working Group reflects the state’s promise to the protection and well-being of its citizens. The recent fires at energy storage facilities in New York, including one on a public school campus, have underscored the importance of vigilance in this rapidly evolving industry. Governor Hochul’s decisive action in forming the Inter-Agency Fire Safety Working Group highlights her commitment to immediate safety inspections and the long-term establishment of best practices. “New York has long been a leader when it comes to battery energy storage policy, and the formation of this new working group proves that the state is committed to ensuring that public safety comes first,” says Alsym CEO and Co-Founder Mukesh Chatter. “In light of recent developments, we encourage the Inter-Agency Fire Safety Working Group to also dedicate time to exploring safer, non-lithium battery options that can be sited in urbanized areas without putting citizens at unnecessary risk.” A member of the New York Battery and Energy Storage Technology Consortium, Alsym Energy fully supports these efforts and stands ready to support state agencies, first responders, and local leaders as they work to ensure the safety and reliable operation of energy storage systems across the state. --- ## Alsym Energy: Lithium-Ion Batteries Pose Dangers for Hospitals URL: https://www.alsym.com/alsym-energy-lithium-ion-batteries-pose-dangers-for-hospitals/ Energy innovator warns against potential safety and health impacts after 80 are evacuated and 3 injured in Florida hospital battery failure Alsym™ Energy, a developer of next-generation rechargeable batteries, echoes the concerns of hospital administrators after lithium-ion batteries went into thermal runaway and released hydrogen gas at Johns Hopkins All Children’s Outpatient Care in Tampa, FL. Following the hospitalization of three employees and evacuation of the facility, 18 fire rescue units, 24 hazmat technicians, and the Hillsborough County bomb squad were called in to inspect and remove the batteries. “A children’s hospital should be one of the safest places in the world for a child, but instead more than 80 people were evacuated and three hospital employees experienced respiratory distress after 30 lithium-ion batteries in an MRI lab released hazardous gases,” says Mukesh Chatter, President, CEO and Co-Founder of Alsym Energy. “Thankfully hospital staff noticed a burning smell and reacted quickly to contact first responders and evacuate patients. But how many other hospitals have similar batteries waiting to fail? Three injuries is three too many, and our kids and medical professionals deserve better than this.” Not only did the damaged batteries continue to release hydrogen into the hospital after evacuation, first responders had considerable difficulty removing the batteries from their storage compartment due to swelling. Two of the 100-pound batteries were visibly ruptured, which could have led to a fire or explosion had a spark or other ignition source been introduced nearby. “Medical devices like MRI scanners need batteries to help regulate the flow of electricity and prevent damage in the event of an outage, but what good is a battery in a hospital if it has the potential to actually create additional health and safety risks?” Chatter continued. “We need new, safer, battery chemistries to help ensure our hospitals never have to be evacuated due to hazardous gases or fires.” --- ## As California Fire Season Ramps Up, Lithium-Ion Grid Storage Batteries Could Complicate Disaster Response URL: https://www.alsym.com/as-california-fire-season-ramps-up-lithium-ion-grid-storage-batteries-could-complicate-disaster-response/ Grid storage fire risks are making alternative battery chemistries critical, warns tech innovator WOBURN, Mass.–(BUSINESS WIRE)–Alsym™ Energy, a developer of next-generation rechargeable batteries, is raising awareness of the dangers of using lithium-ion (Li-ion) batteries in grid storage facilities, especially in California and other areas that are prone to wildfires. As California enters its peak fire season, highly flammable and toxic Li-ion batteries may be vulnerable to catching fire or failing due to elevated ambient temperatures, creating additional instability in the power grid as climate change causes increasingly devastating wildfires. Grid storage fires are especially dangerous in California, where wildfires are on the rise. When a single battery storage container at the Moss Landing Elkhorn Battery Energy Storage Facility in CA caught fire in October 2022, it took two fire crews with four engines nine hours to extinguish the blaze, with several first responders staying on-site overnight in case of re-ignition. While the response was manageable in that instance, a fire at a battery storage facility during a wildfire could divert significant first-responder resources away from the larger disaster. “As more states adopt renewable power sources, storage becomes increasingly vital to grid stability. But most storage facilities use lithium-ion batteries, which can catch fire or generate toxic gasses if they get too hot,” says Alsym CEO Mukesh Chatter. “Not only do burning Li-ion batteries release harmful chemicals into the air and soil, losing storage capacity has the potential to significantly disrupt fragile power grids and complicate disaster response—a major issue for hospitals, communications systems, and other infrastructure that may have limited backup capacity.” The growing popularity of lithium-ion home storage systems could further complicate fire responses. While local utilities require a 100-foot firebreak around substations, the same does not apply to residences in wooded areas. During a wildfire, batteries located in garages or attached to exterior walls may catch fire when exposed to flames or high temperatures, creating a dangerous situation for residents and first responders alike. “Clean energy initiatives put more focus on renewables, requiring more storage to manage intermittent supply,” says Dr. Kripa Varanasi, Alsym Co-Founder and Professor of Mechanical Engineering at MIT. “When it comes to wildfires, burning lithium-ion batteries would make a bad situation worse. We need new inherently non-flammable battery chemistries that do not contain toxic materials to serve our energy needs without endangering our environment, our homes, and our lives.” --- ## Alsym Energy: Fires in Warwick, NY Highlight Dangers of Lithium-Ion Storage in Urban Centers URL: https://www.alsym.com/alsym-energy-fires-in-warwick-ny-highlight-dangers-of-lithium-ion-storage-in-urban-centers/ Energy tech innovator joins city officials in urging communities to re-evaluate safety protocols, zoning, and permit requirements for lithium-ion storage systems near schools, parks, and other high-density areas WOBURN, Mass., July 12, 2023 – Alsym™ Energy, a developer of next-generation rechargeable batteries, joined the Warwick, New York, Village Board in questioning the circumstances that led to two concurrent fires at Convergent Energy battery storage facilities, one of which is located on a public school campus. While the fires did not lead to any injuries thanks to the rapid response of the Warwick Fire Department, this incident only highlights the dangers of the lithium-ion batteries, which are both flammable and prone to releasing toxic chemicals in a fire. “The two lithium-ion battery fires in Warwick, NY are indicative of several critical issues facing the energy storage sector,” says Mukesh Chatter, CEO of Alsym Energy. “Even though battery companies claim that the lower-energy lithium iron phosphate (LFP) batteries used in both installations are safer than higher energy options, these incidents show that they can still catch fire and threaten the health and safety of people living and working nearby. A flammable battery technology, combined with insufficient first responder training and a puzzling choice of site, could have been a recipe for disaster. Luckily school was not in session and no one was hurt, but if the fire on the school campus had happened a month earlier, the situation could have been much different. “We agree with Town Supervisor Michael Sweeton that municipalities should take more time to evaluate safety protocols specific to lithium-ion storage systems, and would also encourage communities to reevaluate zoning and permitting requirements to prevent these facilities from being sited near schools, parks, and other places where large numbers of people congregate. We also find Fire Chief Contaxis’s statement that he received minimal training on these systems to be concerning, and suggest that local leaders take time to learn about newer non-flammable, non-lithium storage options that can serve similar needs with a lower risk factor.” About Alsym Energy Alsym Energy has developed an innovative low-cost, high-performance rechargeable battery chemistry that’s free of lithium and cobalt, and ideal for applications such as stationary storage, maritime shipping, and electric vehicles.
