The Azure Technology Industrial Park located in Feicheng, Shandong Province has welcomed the concentrated construction of three energy storage projects. Among them, the most eye-catching is the Prussian blue based sodium ion battery mass production project invested 4 billion yuan by Shandong Zero 14 Advanced Materials Co., Ltd. The planned annual production capacity of this project is 10 GWh, which is not only the world's first Prussian blue series sodium battery production line to enter the commercial stage, but also marks a crucial step for China in the innovation and industrialization of sodium positive electrode materials.

Prussian blue analog cathode material is regarded as one of the mainstream technology routes for sodium ion batteries in the industry due to its low cost, high energy density, and excellent rate performance. The implementation of this project will promote the large-scale application of sodium batteries in energy storage, low-speed electric vehicles, and other fields, further strengthening China's supply chain autonomy and technological discourse power in the field of new energy batteries.

Shandong Zero One Four Advanced Materials Co., Ltd. has long been committed to the research and manufacturing of sodium ion battery technology, covering multiple green energy links such as positive and negative electrode materials, battery cell manufacturing, and system integration. The company has established multiple core patents in the fields of Prussian blue based battery materials and sodium battery cell technology. In January 2025, the company achieved the official delivery of the world's first Prussian blue based sodium ion battery, preliminarily verifying its technical feasibility and market application potential.
