SNC Batteries Achieve 0.6-1.5% Failure Rate Versus Lithium’s 3-5% Industry Average

Proven Longevity in Tough Conditions

Altech Batteries Limited has released compelling field data confirming the exceptional durability of Sodium-Nickel-Chloride (SNC) batteries, manufactured by its partner AMPower. Operating for over 15 years in South Africa’s telecom and industrial UPS sectors, these batteries have demonstrated failure rates as low as 0.6%, a stark contrast to the 3-5% failure rates typical of lithium-ion batteries.

The SNC batteries have endured extreme temperatures exceeding 50°C, frequent power interruptions, and remote deployment without the need for maintenance or electrolyte replacement. This track record underscores their suitability for critical infrastructure applications where reliability is paramount.

Why SNC Outperforms Traditional Chemistries

The secret to SNC’s longevity lies in its solid-state ceramic construction and sealed design. Unlike lithium-ion or lead-acid batteries, SNC batteries contain no flammable electrolytes or venting gases, eliminating common failure modes such as dendrite formation, electrolyte degradation, and corrosion. Their beta-alumina ceramic electrolyte enables stable ion transport even if minor cracks develop, maintaining conductivity and preventing sudden failure.

This robust chemistry allows SNC batteries to operate safely at elevated temperatures (~270°C) and maintain capacity over 15-20 years, often surpassing the lifespan of competing technologies. Additionally, SNC batteries require no active cooling or ventilation, significantly lowering operational complexity and costs.

Strategic Implications for Altech

Altech’s Managing Director, Iggy Tan, highlighted that these findings validate the company’s strategic focus on SNC technology, particularly for European pipeline and hydrogen infrastructure projects. The technology’s fireproof and explosion-proof characteristics make it ideal for hazardous environments, including ATEX zones and remote industrial sites.

Moreover, the partnership with AMPower, a subsidiary of the major Chinese battery manufacturer Chilwee Group, positions Altech to scale production and distribution across Australia, Europe, and the United States. This collaboration leverages AMPower’s established manufacturing capabilities and Altech’s proprietary technology developments, including the CERENERGY solid-state battery and Silumina Anodes for EV applications.

Cost and Environmental Advantages

The SNC battery’s minimal maintenance requirements and long service life translate into a lower total cost of ownership compared to lithium-ion and lead-acid batteries. Additionally, SNC batteries avoid the use of critical metals such as lithium, cobalt, and copper, mitigating supply chain risks and environmental concerns associated with mining and disposal.

With zero hydrogen emissions and full recyclability, SNC technology aligns well with increasing regulatory and market demands for sustainable energy storage solutions.
