Zhongguancun Intelligent Electric Power Industry and Technology Alliance (EPTC) AC/DC Power Supply System Specialized Committee Visited Chaowei AMPower for an In-depth Investigation of Sodium Salt Battery Technology Achievements

On the morning of May 9, 2025, the inaugural meeting of the AC/DC Power Supply System Professional Committee of Zhongguancun Intelligent Electric Power Industry and Technology Alliance (EPTC) and the Seminar on Innovative Storage Battery Technology was successfully held in Changxing, Zhejiang Province. Representatives from national research institutes, power system enterprises and energy storage industry gathered together to carry out in-depth exchanges around the development trend of power system and the cutting-edge technology of storage battery, and to jointly promote the green and low-carbon transformation of power system.

Sodium salt battery technology unveiled to crack the transmission and distribution network pain points

In the seminar on innovative storage battery technology, Yu Zhenjiang, Deputy General Manager of Chaowei AMPower, took "Application of Sodium Salt Battery in Power Transmission and Distribution Networks" as the theme, and systematically explained the technological breakthroughs of sodium salt batteries in the areas of high safety, long life, and wide-temperature range operation, etc. He pointed out that the current power system is facing the challenge of fluctuation caused by the high proportion of new energy access. He pointed out that the current power system is facing the volatility challenge brought by the high proportion of new energy access, and the safe, economic and sustainable energy storage technology needs to be developed urgently. He pointed out through empirical data that the sodium salt battery developed by the company can be stably charged and discharged under the environment of -40℃ to 65℃, with a cycle life of more than 6,000 times, and with intrinsic safety characteristics, perfectly adapted to the scenarios of substation standby power, microgrid frequency regulation, etc." Through modularized design, sodium salt battery can flexibly match the energy storage demand from kilowatt to hundred megawatt level, and the full life cycle cost is 40% lower than traditional lead-acid batteries.

Field visit hardcore strength Comprehensive display of technical heritage

After the meeting, EPTC expert group visited Zhejiang AMPower Co., Ltd. to conduct in-depth research and communication on the development of sodium salt battery technology. The senior management of the company received them warmly and accompanied them throughout the visit.

During the visit, the experts first walked into the sodium salt battery showroom. Mr. Yu, the general manager of the company, played a number of safety test videos of sodium salt batteries on site, including fire, short circuit, pinprick, extrusion and other harsh test scenarios, which fully demonstrated their excellent safety performance and environmental adaptability. In addition, Mr. Yu also highlighted various product models of sodium salt battery and modular UPS system, which is applied in key scenarios such as industrial power supply and data center with the advantages of flexible expansion, intelligent management and high energy efficiency, reflecting the company's technological precipitation and market layout in the field of intelligent power supply system, and introduced the results of the application of sodium salt batteries in a number of domestic and international energy storage demonstration projects, which gained the high degree of attention of the guests. The company also introduced the application results of sodium salt battery in many energy storage demonstration projects at home and abroad, which gained high attention from guests.

During the visit to the laboratory and production workshop, the experts gained an in-depth understanding of the company's product R&D, testing and production processes, learning about the whole process from material processing, core manufacturing, module assembly to system testing. The automated equipment in the workshop operates orderly, reflecting the modern manufacturing level of high standardization and informationization.

Deepening Understanding and Promoting Cooperation

The visit of Zhongguancun EPTC AC and DC power supply system professional committee further deepened the understanding of industry experts on sodium salt battery technology and industrialization path, and also laid a foundation for subsequent cooperation in the construction of standards, joint technology research, and promotion of demonstration projects.

In the future, AMPower will continue to promote the key technology breakthroughs and industrial chain improvement of sodium salt battery, help the development of new energy storage system, and contribute to the construction of a new type of safer, more efficient, and greener power system with "Anli Power".
