[Sodium Battery: Prussian Blue Sodium Battery Completes Thousand-Ton Capacity Construction]

In March 2026, China’s phosphate ore imports reached 182,000 mt, up 88.2% MoM and 144.4% YoY, with an average price of $79.9/mt, down 7.2% MoM.Affected by Strait of Hormuz disruptions, Jordan halted supplies for the first time since September 2023. Imports mainly came from Egypt (170,000 mt) and Pakistan (12,000 mt), through Guangxi, Hubei and Fujian.

This week, the sodium-ion battery industry operated steadily overall, with industry prosperity continuing to rise. On the technological front, key performance metrics such as high safety, long cycle life, and low cost continued to achieve breakthroughs, laying a solid foundation for large-scale applications. With policy and industry working in synergy, upstream and downstream projects along the industry chain advanced steadily. Supporting infrastructure across materials, battery cells, system integration, and end-use applications continued to improve, with capacity deployment gradually materializing. The pace of scenario validation in energy storage, telecom backup power, and other fields accelerated, and market recognition of sodium-ion batteries' substitution and complementary effects increased. Overall, the industry is demonstrating a development trend characterized by **accelerating technological iteration, broadening application scenarios, and an increasingly mature industry chain**. The industrialisation of sodium-ion batteries continues to advance, with a promising medium and long-term development outlook.

On April 13, Hithium announced that it plans to establish an international R&D center in Hong Kong, China, focusing on long duration energy storage (LDES) and sodium-ion battery technologies, forming a global R&D synergy with its bases in Xiamen, Chongqing, Shenzhen, and other locations. The company's Hong Kong IPO is proceeding as planned. Hithium began its sodium-ion battery deployment in 2023. In December 2024, it released the **∞Cell N162Ah polyanion sodium-ion energy storage battery cell, which achieves a capacity retention rate of 94.2% after 4,000 cycles at 25°C, with a projected lifespan exceeding 20,000 cycles**. The company has launched a lithium-sodium synergistic energy storage solution, compatible with AIDC, power grid, and other scenarios.
