Recently, according to publicly available information from the National Intellectual Property Administration, ZheJiang VASTSIB Technology Co., Ltd. (hereinafter referred to as "our company"), in collaboration with TianJin VASTSIB Technology R&D Co., Ltd. and JiangSu VASTSIB Technology Co., Ltd., successfully filed a patent application titled "Thermal Management System for Sodium-Ion Energy Storage Devices and Energy Storage Stations" (Publication No.: CN120341439A). The patent application was filed in June 2025, marking an important breakthrough for our company in the core technological field of sodium-ion energy storage.

　　As the core leading enterprise behind this patent application, our company has been deeply engaged in the R&D and industrial implementation of sodium-ion battery technologies for many years. Since our establishment in Jiaxing City in 2022, with a registered capital of 22.8 million RMB as our foundation, we have focused on other key manufacturing sectors. Thanks to continuous R&D investment and technological innovation, we have accumulated a total of 17 patent filings. Additionally, we have participated in seven bidding projects, secured one trademark registration, and obtained two administrative licenses, thereby establishing a comprehensive R&D system and a robust market operational network. Furthermore, we have actively expanded our industrial ecosystem by making external investments in four enterprises, creating a diversified industrial landscape that covers R&D, production, and application—thus laying a solid foundation for this cross-regional technology collaboration.

　　The patent for the thermal management system jointly applied for this time represents an important achievement of our company’s integration of industrial-chain resources and collaborative innovation. This system innovatively adopts a dual-dimensional heat-exchange design—combining “above-ground” and “underground” approaches. By incorporating above-ground heat exchangers and temperature sensors within the sodium-ion energy storage device, coupled with multiple underground heat exchangers and corresponding temperature sensors dispersed beneath the ground, the system achieves precise temperature control of the energy storage unit. Meanwhile, through the intelligent interconnection of piping systems and control units, the system can dynamically adjust heat-exchange efficiency based on real-time temperature data, offering core advantages such as energy efficiency, high performance, low cost, and compact size. The implementation of this technology will effectively address the thermal management challenges encountered during the operation of sodium-ion energy storage devices, significantly enhancing the stability and service life of these systems and providing crucial technical support for the large-scale adoption and commercial application of sodium-ion energy storage solutions.

　　Among the affiliated companies involved in this collaboration, TianJin VASTSIB Technology R&D Co., Ltd. (established in 2024 with a registered capital of 9.5 million RMB) focuses on technology promotion and application services, accumulating a total of 8 patent filings and participating in 4 bidding projects, providing professional technical support for patent R&D. JiangSu VASTSIB Technology Co., Ltd. (established in 2024 with a registered capital of 30 million RMB) is deeply engaged in the manufacturing of electrical machinery and equipment, and leveraging its two patented technologies, it has developed unique advantages in the production and manufacturing of energy storage devices. The three companies are carrying out in-depth collaboration based on industrial complementarity, achieving technological synergy across R&D, manufacturing, and application stages, thereby highlighting the industry ecosystem aggregation effect led by our company.

　　In the future, our company will continue to take technological innovation as the core driving force, further deepen collaborative partnerships with affiliated enterprises, and accelerate the industrialization and commercialization of this patented technology. At the same time, we will increase R&D investment in the field of sodium-ion energy storage, continuously break through key technological bottlenecks, and contribute more “VASTSIB power” to the high-quality development of China’s new-energy storage industry!
