World's First Sodium-Ion Electric Haul Truck Enters Commercial Operation in China

World's First Sodium-Ion Battery Electric Haul Truck Deployed in Chinese Mine

Chinese equipment manufacturer Tonly Heavy Industry, in collaboration with Hina Battery, has successfully deployed the world's first sodium-ion battery electric haul truck at the Tangshan Sanyou limestone mines. The K120E model features a 676 kWh 'Haixing' battery pack, achieving an energy density of 165 Wh/kg and an impressive operational lifespan of over 8,000 cycles.

Strategic Advantages for Heavy-Duty Mining and Logistics

This deployment highlights sodium-ion technology's distinct benefits for industrial applications:

• Superior Cold-Weather Performance: Designed for northern China's extreme cold (as low as -20°C), sodium-ion batteries maintain efficiency where diesel engines struggle to start, and lithium-ion range deteriorates.
• Enhanced Safety & Cost-Effectiveness: Offers improved thermal stability (fire safety) compared to lithium-ion and utilizes geopolitically stable, lower-cost raw materials, reducing supply chain vulnerabilities.
• Rapid Charging & Longevity: Supports ultra-fast charging (0-100% in minutes) and a massive cycle life, significantly reducing downtime in continuous mining operations.

Implications for B2B Buyers and Industrial Fleets

This commercial validation positions sodium-ion as a viable, strategic alternative to lithium-ion for heavy commercial vehicles. For B2B buyers in mining, port logistics, and construction, this means:

• Lower Total Cost of Ownership (TCO): Reduced upfront material costs and longer battery life lower per-ton operational expenses.
• Operational Reliability: Consistent performance in harsh environments improves fleet uptime and worker safety (reducing cold-related risks and diesel exhaust exposure).
• New Supply Chain Avenues: Diversifies battery sourcing, mitigating reliance on traditional lithium supply chains.

This initiative, part of a broader 800-unit autonomous truck delivery to Xinjiang Hanxiang, underscores a major industry shift towards sustainable, all-weather, and autonomous heavy equipment.
