Massachusetts-based battery maker, Alsym Energy, has introduced its latest Na-Series sodium-ion battery for stationary energy storage applications. 

The company lists enhanced safety, cost-effectiveness, and a wide operating temperature range compared to lithium-based counterparts, while maintaining an equitable energy density, as the primary attributes of this product. 

Unlike lithium-ion-based electrolytes, which use lithium salts (like lithium hexafluorophosphate or LiPF₆) in highly flammable organic carbonate solvents, the sodium-ion alternative consists of less reactive and thermally more stable sodium salts. This attribute makes the company’s Na-Series batteries ‘non-flammable’ during cell overheating or getting damaged, compared to standard lithium-ion-based peers. Unlike the latter, which use toxic heavy metals, including cobalt and nickel, it uses non-toxic and easier to recycle iron, manganese, or vanadium-based compounds. Therefore, the company characterizes its battery as a ‘non-toxic’ product that is safer and easier to recycle. The company states that the abundance and lower cost of sodium (Na) minerals make the batteries’ auxiliary system simpler, thereby reducing a storage project’s CapEx and OpEx and lowering the levelized cost of storage (LCOS).  

In addition to the above-mentioned advantages, the company emphasizes fast charging and discharging capabilities, making the platform suitable for energy storage applications in data centers, industrial operations, oil and gas, and defense installations. These use cases demand multiple daily charging and discharging cycles.  

The company states that the domestically manufactured battery supports system integrators and original equipment manufacturers (OEMs) with improved supply chain security by sourcing materials from non-FEOC entities. The enactment of Foreign Entity of Concern (FEOC) under the One Big Beautiful Bill Act (OBBBA) restricts tax credits under the Inflation Reduction Act (IRA) for Chinese investment in US-based energy storage projects. 

The company has not shared the commercialization details for this product; however, it is collaborating with strategic partners and inviting new stakeholders to support its advancement.
