Ningbo Shengrun Participates in Drafting, Contributing to a New Benchmark for Battery Safety

On May 25, 2026, my country's first national standard for the thermal protection performance of thermal insulation sheets for power batteries, GB/T 47613-2026 "Test Methods for Thermal Protection Performance of Thermal Insulation Sheets," was officially released and will be implemented on December 1, 2026. As a participating drafting unit, Ningbo Shengrun was deeply involved in the entire standard development process, using its professional strength to help the industry achieve standardized and high-end development.

I. National Standard Release: Filling an Industry Gap, Building a Solid Foundation for Battery Safety

With the rapid growth of the new energy vehicle and energy storage industries, the thermal safety of power batteries has become a core issue for the high-quality development of the industry. As a key material for passive safety in battery packs, thermal insulation sheets can effectively block heat transfer between cells, buffer impacts, and inhibit the spread of thermal runaway, serving as an important barrier to protect the safety of battery systems.

Previously, the industry lacked a unified, real-world-like method for evaluating thermal protection, making product performance difficult to compare and resulting in inconsistent quality, thus hindering industry upgrades. This newly released national standard, for the first time, adopts the cold-plate compression method to realistically simulate the extreme scenario of rapid temperature rise and pressure transfer on hot surfaces during thermal runaway. The test is scientific, repeatable, and cost-effective, covering all scenarios from R&D screening to mass production acceptance, establishing an authoritative evaluation benchmark for the industry.

II. Shengrun's Responsibility: Leading with Standards, Safeguarding Safety with Technology

Ningbo Shengrun New Materials, an innovative enterprise specializing in the R&D, production, and application of aerogel insulation materials, has deep roots in the new energy thermal protection field. With its mature material system, stable mass production capabilities, and stringent quality control system, it was selected as a drafting unit for this national standard, working alongside leading industry companies and research institutions to promote its implementation.

During the drafting process, Ningbo Shengrun, drawing on its experience in the mass application of power battery thermal insulation sheets and aerogel thermal insulation components, offered numerous constructive suggestions regarding key aspects such as testing conditions, performance indicators, and data repeatability. These suggestions helped make the standard more aligned with industry realities and more practical, showcasing the company's technological expertise and industry responsibility in the field of thermal protection materials.

III. Standard Empowerment: Opening a New Track for Thermal Protection Materials

The release and upcoming implementation of this standard have profound significance:

★ Unified Evaluation Benchmark: Providing authoritative basis for enterprise R&D, factory inspection, quality acceptance, and market transactions, thus regulating market order.

★ Breaking Application Boundaries: Breaking the traditional application limitations of thermal insulation materials, pioneering a national standard for thermal protection insulation materials, and promoting the standardization of thermal insulation materials into high-end fields such as new energy and energy storage.

★ Supporting Industrial Upgrading: Guiding enterprises to focus on technological innovation and quality improvement, accelerating the popularization of high-performance, high-safety thermal insulation materials, and supporting the safe, green, and high-quality development of the new energy industry.

IV. Shengrun New Materials: Continuous Deep Cultivation, Safeguarding Safety at Every Degree

As a participating enterprise in the drafting of national standards, Ningbo Shengrun will take this standard release as an opportunity to continuously increase R&D investment, optimize the performance of core products such as aerogel insulation sheets and power battery insulation components, strictly adhere to national standard requirements, and provide customers with safer, more efficient, and more reliable thermal protection solutions.

In the future, Ningbo Shengrun will continue to uphold technological innovation, deeply participate in the construction of industry standards, and work hand in hand with industry chain partners to jointly build a new energy safety defense line, contributing to the high-quality development of my country's power battery and energy storage industry!
