Abstract:

[Objective] This paper focuses on the study and interpretation of IEC TS 62565-5-3:2025, with the objective of facilitating its practical implementation and promoting the large-scale production and commercial adoption of silicon nanosized anode materials. [Methods] A systematic analysis and detailed interpretation of the standard are conducted. The study explicitly lists 31 key control characteristics—encompassing physical, chemical, electrochemical, and structural aspects—along with their corresponding test methods. Furthermore, a maturity matrix is employed to assess and summarize the standardization readiness of existing test methods for each key characteristic. [Results] IEC TS 62565-5-3:2025 represents the first comprehensive framework establishing key control characteristics and measurement methods for silicon nanosized anode materials in lithium-ion batteries. This paper clearly identifies and organizes all 31 indicators and associated test standards, providing an essential technical foundation for material production and quality control. The maturity matrix offers a clear visual representation of the current standardization status of test methods for each characteristic. [Conclusion] This paper demonstrates that IEC TS 62565-5-3:2025 lays a crucial foundation for the standardized development of silicon nanosized anode materials. Based on the analysis, this paper provides constructive recommendations for future standardization efforts aimed at further advancing and refining the framework for these materials, thereby supporting continued technological progress and industrial development in the field.
