Sodium-First Infrastructure

Not a lithium adaptation.
A platform engineered sodium-first.

ALF5ESS containerised system deployed near critical infrastructure Chemical Integrity
01 — Chemical Sovereignty

Zero Thermal Runaway.
Total Infrastructure Confidence.

Powered by ALIFE AIR's proprietary Sodium-Ion cell architecture, the ALF GridVault™ Na Series eliminates thermal runaway risk not as a mitigation — but as an intrinsic property of sodium chemistry itself. Deploy with absolute confidence adjacent to critical infrastructure, urban grid assets, and high-value industrial environments.

  • Sodium chemistry: thermal runaway is structurally impossible at the cell level
  • Cleared for deployment adjacent to sensitive and critical infrastructure
  • Integrated automated clean-agent fire suppression as standard
ALF5ESS operating in extreme arctic and desert environments Climate Resilient
02 — Climate-Invariant Performance

Any Climate.
Full-Rated Performance.

Engineered to perform where conventional lithium systems derate and fail. Across freezing mountain installations and scorching arid deployments, the ALF GridVault™ Na Series maintains full-rated output throughout a -20°C to 60°C operating range — supported by industrial air cooling and an IP54-rated, C3-treated enclosure built for the harshest environments on Earth.

  • -20°C to 60°C operational range — no derating, no thermal degradation
  • IP54-rated enclosure with full C3 industrial anti-corrosion treatment
  • Standard industrial air cooling — high-performance liquid cooling available
Large-scale solar farm integrated with ALF5ESS grid energy storage Lithium-Free Sovereignty
03 — Supply-Chain Sovereignty

No Lithium.
No Exposure.

The ALF GridVault™ Na Series carries zero exposure to lithium, cobalt, or nickel — the three commodities driving instability across the conventional storage supply chain. Built on earth-abundant sodium, the platform delivers 10,000+ cycles across 15–20 years of daily operation with a stable, predictable cost structure engineered for institutional financial planning and infrastructure-grade procurement.

  • Zero exposure: no lithium, no cobalt, no nickel in the supply chain
  • Earth-abundant sodium — geopolitically neutral and globally accessible
  • Stable, predictable long-term cost architecture for institutional finance
