The Problems We Help You Solve
Flammability Drives Up Costs and Kills Deals
Lithium-ion fire risk adds OEM safety costs and pushes thousands in compliance expenses onto customers—assuming flammability concerns don’t stop the project outright.
Installations Are Slower, Riskier, and Harder to Scale
Hazmat shipping costs, fire code placement restrictions, and safety protocols create logistics headaches and slow installation timelines.
Performance Drops in Harsh Weather
Summer heatwaves and winter freezes degrade usable battery capacity when it’s needed most to offset rising energy bills. Derated performance leads to warranty claims, customer dissatisfaction, and costly field service calls when systems underperform during peak demand periods.
The Benefits of Alsym Na-Series
Safe, Simple Energy Storage for Every Home
Alsym’s Na-Series battery cells help OEMs/Integrators provide better energy storage solutions for residential.
Easier Sales with Non-Flammable Chemistry
Alsym’s non-flammable chemistry reduces permitting hurdles, avoids fire-rated enclosures, and eases insurer concerns—cutting hidden costs and making energy storage a simpler choice for customers.
Faster and Simpler to Deploy
Alsym batteries can be shipped at 0% state-of-charge and do not need thermal management add-ons. These features reduce installer risk and streamline installation from delivery to commissioning.
Consistent Capacity in All Seasons
Designed to perform thousands of cycles without thermal constraints, sodium-ion batteries maintain high usable capacity year-round—maximizing solar usage, backup coverage, and long-term homeowner value.
Typical Use Cases for Residential
Backup Power
Provide reliable backup power when primary systems fail, with the ability to fully discharge to 0% state of charge without degradation. Safe, fire-free operation supports long runtimes for critical loads.
Solar Self-Use
Store excess onsite solar energy for later use during peak demand or when renewable generation is low. Alsym batteries cycle daily without degrading and maintain >95% round-trip efficiency year-round, giving customers best-in-class return on their investment.
Peak Shaving
Store low-cost electricity during off-peak hours and discharge during peak times to cut utility bills. Or, send energy back to the grid with unlimited 2C/4C charge/discharge cycles to take full advantage of consumer demand response programs.
A Better Solution for our Energy Future
Alsym’s Na-Series battery platform is designed to go where lithium-ion can’t—safely, affordably, and at scale. From city rooftops to off-grid communities, we’re building storage that fits the future.
