Standards Development

Scope

This document specifies the technical requirements, test methods, and performance evaluation indicators of inorganic heat-resistant coatings used in electrochemical energy storage battery systems, and is suitable for thermal runaway protection of coatings in battery cells, modules, and system-level applications.

Note: This document does not specify the types of battery systems or substrates suitable for heatresistant coatings, nor does it define detailed requirements for coating appearance or application methods. Instead, it defines the core performance metrics essential for ensuring safety and functionality under operational conditions.

Purpose

The safe operation of electrochemical energy storage systems depends heavily on the thermal management performance of their coatings. Currently, performance requirements for such coatings vary significantly across manufacturers and regions, leading to inconsistencies in safety, reliability, and international trade. The rapid expansion of the battery energy storage market further intensifies the need for harmonization, underscoring an urgent need for standardized specifications for heat-resistant coatings. These coatings play a critical role in mitigating thermal runaway risks, which can propagate across battery cells and cause catastrophic failures. Inorganic thermal insulation coatings, in particular, have demonstrated superior safety performance compared to organic alternatives. This document aims to enhance the safety, reliability, and interoperability of electrochemical energy storage systems by providing a unified framework, benefiting manufacturers, suppliers, and end-users worldwide. Through the establishment of consistent and internationally recognized benchmarks, standardized testing methods and performance criteria will reduce technical barriers to trade and promote innovation in coating technologies for the energy storage sector.
