AMPower Leads The Release Of China's First National Standards For High-Temperature Sodium-Based Batteries - News

Recently, two national standards led and drafted by Zhejiang AMPower Co., Ltd.-"High-Temperature Batteries – Part 1: General Requirements" (GB/T 46735.1-2025) and "High-Temperature Batteries – Part 3: Sodium-Based Batteries – Performance Requirements and Test Methods" (GB/T 46735.3-2025)-have been officially approved and published. Both standards will come into force on May 1, 2026.

This milestone marks a new phase of standardization and regulatory development for China's sodium-based battery industry. The release of these standards fills a long-standing gap in the domestic high-temperature sodium battery sector and further demonstrates AMPower 's technological leadership in the field of sodium-nickel (salt) batteries.

High-Temperature Batteries – Part 1: General Requirements

As a foundational and universal standard, this document specifies key technical requirements for high-temperature batteries with a rated voltage not exceeding 1500 V and a minimum internal operating temperature above 100°C. It defines terminology, design principles, environmental adaptability, test methods, marking, transportation, and maintenance requirements. The standard has been optimized to align with China's technical conditions while referencing relevant international norms, providing a unified technical benchmark for the research, development, and manufacturing of high-temperature batteries.

High-Temperature Batteries – Part 3: Sodium-Based Batteries – Performance Requirements and Test Methods

This standard focuses specifically on sodium-based batteries, including sodium–sulfur and sodium–nickel chloride batteries. It clearly defines critical performance indicators such as energy efficiency, cycle life, and thermal stability under high-temperature operating conditions, along with standardized test methods. By adopting advanced international standards with necessary localization, it ensures both global alignment and practical applicability, offering precise criteria for quality control of sodium battery products.

The establishment of national standards relies on deep technical expertise and practical industry experience. As a key drafting organization, AMPower has been deeply engaged in the high-temperature battery sector for many years and maintains a leading technological position in the industry. The company has passed multiple provincial-level new product evaluations and is also the first company in China to obtain UL 9540A cell-level certification.
