Zhejiang King Sodium Technology Co., Ltd. was established in November 2024, focusing on the research, development, and manufacturing of sodium-ion batteries, as well as the development, application, and sales of energy storage system technologies. The company is committed to advancing the industrialization of next-generation energy storage battery technologies and providing high-safety, high-performance energy storage solutions for large-scale energy storage and emerging energy applications.
The company’s manufacturing base is located in Dongyang, Zhejiang Province, an important economic city in the southern wing of the Yangtze River Delta. The region is characterized by strong economic vitality, abundant high-end talent resources, and a well-developed industrial supply chain, providing an excellent environment for technological innovation and industrial development. In June 2025, the company’s core production equipment was gradually installed and commissioned. After installation, debugging, and trial operation, the production line officially entered the trial production stage in October 2025, and the company has now achieved scaled mass production.
Zhejiang King Sodium Technology Co., Ltd. has established a deep technical cooperation with Shenzhen King Sodium Technology Co., Ltd. Since its establishment, Shenzhen King Sodium Technology Co., Ltd. has focused on the research and development of sodium-ion battery products, manufacturing equipment, and process technologies. Through years of technological accumulation, the company has obtained multiple patents, successfully overcoming several key technological bottlenecks and achieving significant advantages in sodium-ion battery technology, product development, and equipment innovation.
In 2024, the two companies initiated technical cooperation and jointly established a production base in Dongyang, Zhejiang, becoming the first in the industry to industrialize MEGA-SIB technology. MEGA-SIB developed by the company are at the forefront of the industry, featuring excellent low-temperature performance, long cycle life, and extremely high safety, with characteristics such as no fire and no explosion. These batteries can be widely applied in large-scale energy storage power stations, AI data center energy storage systems, and other high-performance energy storage applications. The company’s technology roadmap and products have gained broad recognition within the battery industry.
Looking ahead, Zhejiang King Sodium Technology Co., Ltd. will continue to focus on the research, development, and industrialization of sodium-ion battery technologies, promoting innovation in next-generation energy storage technologies. The company is committed to becoming a globally competitive provider of advanced energy storage battery technologies and products, contributing to the global energy transition and the development of a green, low-carbon future.
