Altech Batteries (ASX:ATC) has reported destruction testing of its sodium-nickel-chloride (SNC) batteries showed zero fire events when deliberately trying to trigger thermal runaway, a feat that was also pulled off without risk of explosion.

“Full mechanical and chemical stability” is what Altech described its SNC batteries demonstrating during the testing, which, all cards in order, works to prove the general idea behind the competitor SNC format (as opposed to lithium) – that lithium-ion batteries, particularly ‘big batteries’ used in energy storage, are obscenely hard to put out if they catch fire.
Introduction to water (either fresh or saltwater) produced the ‘non-violent’ release of steam, and in what is perhaps the crowning achievement, the company reported SNC battery cells were intact even after being exposed to a gasoline fire for 30 minutes.
(Technicians even shot at the SNC modules with a gun, producing ‘brief smoke.’ Must be a fun job.)
“Across all scenarios — including direct fire exposure, rod penetration, over-charge, ballistic impact, drop test, impact test and submersion — the SNC cells and modules demonstrated exceptional chemical stability and mechanical resilience,” Altech wrote of its testwork.
“No explosions, thermal runaways, or uncontrolled reactions were recorded in any test. The results confirm what long-term field deployments have already indicated: SNC batteries are intrinsically safe, thermally robust, and chemically contained, even when exposed to conditions [more extreme than standards account for].”
ATC last traded at 3.6cps.
