Charged EVs | Altech demonstrates security of sodium-nickel-chloride batteries underneath harmful check situations

Strong-state battery developer Altech Batteries has accomplished a full suite of security self-destruction validation assessments on its sodium-nickel-chloride (SNC) battery expertise, which it just lately started promoting.

The assessments had been designed to simulate essentially the most extreme discipline hazards that may happen throughout storage, transport or operation. Throughout all of the situations, which included direct fireplace publicity, rod penetration, over-charge, ballistic influence, drop check, influence check and submersion, the SNC cells and modules demonstrated chemical stability and mechanical resilience. No explosions, thermal runaways or uncontrolled reactions had been recorded within the assessments, Altech mentioned.

The SNC cells remained sealed and intact after being uncovered to an 850° C gasoline fireplace for half-hour, whereas rod penetration and water publicity produced solely innocent steam. The flames had been extinguished inside one minute. A drop of 10 meters onto a metal pole, simulating an influence at roughly 30 mph and crash at 48 km/h triggered minor dents, with out leakage or rupture. Immersion for two.5 hours in 3.5% saltwater didn’t trigger any exterior response or voltage loss, whereas an over-charge at 145% nominal voltage for one hour produced no venting, swelling or warmth era. Bullet impacts solely triggered temporary smoke, whereas the construction and voltage remained secure.

“These impartial abuse assessments verify what long-term discipline information has been telling us for years—our sodium-nickel-chloride expertise batteries produced by associate firm AMPower, are exceptionally protected,” mentioned Altech Managing Director Iggy Tan. “Even underneath direct fireplace, influence or over-voltage, the cells stay sealed and secure. This degree of intrinsic security is a significant differentiator for Altech. Our SNC batteries can endure situations nicely past certification limits whereas sustaining integrity and efficiency.”
