GB/T 46735.3-2025 High-temperature secondary batteries—Part 3:Sodium-based batteries—Performance requirements and tests
Basic Information
Scope
This document specifies the performance requirements and test methods for sodium-based high-temperature batteries used in mobile and/or stationary applications with a rated voltage not exceeding 1,500 V.
Sodium-based batteries include sodium-sulfur batteries and sodium-nickel chloride batteries. Both are high-temperature batteries and use sodium-conductive solid electrolytes. For more information on sodium-based battery technology, chemical composition, and structure, see Appendix A.
This document applies to sodium-based high-temperature batteries used in mobile and/or stationary applications with a rated voltage not exceeding 1,500 V.
This document does not apply to aviation batteries covered by IEC 60952 (all parts) and electric road vehicle propulsion batteries covered by IEC 61982 (all parts).
Note: High-temperature batteries are electrochemical systems with a minimum operating temperature of over 100°C within the individual battery cells.
