Altech Batteries (ASX:ATC) has marked its sodium-nickel-chloride battery technology as ‘intrinsically safe’, after completing a full-suite of safety self-destruction validation tests.
The results confirm what long-term field deployments have already indicated, that the technologies are safe and thermally robust, and chemically contained, even when exposed to conditions far beyond those specified under international certification standards.
Across all scenarios – cell fire and module fire exposure, ten metre drop test, module rod penetration test, module impact, saltwater exposure, overcharge and bull impact tests – the cells and modules showed chemical stability and mechanical resilience.
Altech says there were no explosions, no rupture of the cell casing, and no leakage or release of internal materials. The cells remained structurally intact throughout the test.
Managing Director Iggy Tan says as global energy-storage installations increase near population centres and critical infrastructure, regulators and customers are demanding non-flammable chemistries.
“We are proud to demonstrate that our sodium-nickel-chloride batteries can endure conditions well beyond certification limits while maintaining integrity and performance,” Tan says.
“This gives confidence to partners, insurers, and end-users that sodium-nickel-chloride systems deliver not only long cycle life and temperature tolerance but also unmatched safety.”
Altech’s CERENERGY batteries, also known as sodium-nickel-chloride batteries, have been developed over the last eight years and have revolutionised previous technology, allowing higher energy capacity and lower production costs.
