Developed under the auspices of the Standardization Committee of China International Association for Promotion of Science and Technology, Zonergy was invited to lead the drafting, and the standard officially took effect in June 2026. The standard extends normative requirements for sodium-ion technology from the cell level to complete energy storage systems. It covers application scenarios including microgrids, PV-integrated applications, backup power supply and off-grid power supply, and sets differentiated requirements for commercial and industrial (C&I) and residential scenarios. It specifies detailed performance metrics for sodium-ion energy storage systems across different scenarios, including capacity deviation, charge-discharge efficiency, cycle life, environmental adaptability and safety protection. Corresponding test methods and inspection rules are also defined, providing a normative basis for the design, manufacturing, performance assessment, safe operation, maintenance and management of sodium-ion energy storage products.
The issuance and implementation of this standard will help advance sodium-ion battery technology from cell R&D toward system integration and end-use applications, raise the standardization level of sodium-ion energy storage products, and enable deeper integration of sodium-ion technology with commercial & industrial storage, residential storage and distributed PV-storage systems. It delivers a standard basis and normative guidance for the industrialization and large-scale adoption of sodium-ion batteries.
▲ Plaque
Leading the drafting of this group standard and receiving the corresponding certificate and plaque is not only recognition of Zonergy’s active contribution to industry standardization, but also solid evidence of its commitment to integrating technological innovation with industrial practice. Zonergy will continue to deepen R&D on core sodium-ion battery technologies, take an active part in building the industry standard system, accelerate the commercialization of technological innovations, and expand the practical deployment of sodium-ion products across diverse scenarios. The Company will support the sodium-ion battery industry in advancing toward standardized, large-scale and high-quality growth, and contribute more of its strength to the new energy sector.
