TECHNOLOGY
Built for Energy Storage
Battery storage is critical for electrification and a stable, flexible electric grid. But concerns about safety and unpredictable supply chains continue to limit widespread deployment.
Alsym’s answer is the Na-Series: A sodium-ion battery engineered to meet the specific needs of energy storage. We build cells and modules for OEMs/integrators to use in their energy storage systems. The resulting solutions are non-flammable, high-performance, affordable, and built for the demanding requirements of energy storage.
Why Alsym
Na-Series?
Alsym’s Na-Series NFPP sodium-ion batteries offer a scalable, cost-effective, and non-flammable solution, offering a host of widely applicable benefits:
Safety Profile
Our unique chemistry formulation completely erases the risk of fires and toxic gases. This enables energy storage deployments in settings where fire concerns restrict lithium-ion deployments.
Cycle Life
Na-Series batteries are built to handle deep discharge, with up to 10,000 cycles or 20 year service life. Robust hard carbon and stable electrodes reduce the range of mechanisms causing degradation in Li-ion batteries.
Resource Abundance
Sodium is a resource more widely distributed than lithium and 1000x more abundant according to estimates, making it the optimal choice for long-term supply security.
0% State of Charge
Na-Series batteries use aluminum current collectors that don’t face the same dissolution issues as the copper used in lithium-ion. Can be shipped or stored completely empty without damage, simplifying logistics.
Fast Charge and Discharge
Unlike lithium, the Na-Series can charge and discharge up to 2C and 4C, respectively, without shortening system service life. This gives operators a highly flexible energy asset to meet changing demands over the life of the system.
Wide Operating Temperature Range
Performs reliably across a significantly wider temperature range than Li-ion, making it the more robust choice for systems intended for hot, cold or exotic climates without the need for intensive battery management and HVAC.
Alsym Na-Series
The Alsym Sodium-ion is based on a proprietary chemistry that is high-performance, non-flammable, and affordable and is manufactured with a US and US allies supply chain.
