At the "Invest in China" Germany Special Presentation event hosted by the Ministry of Commerce of China, a German expert team has developed a complete set of high-performance and high-security solid-state sodium sulfur battery automatic continuous production process after nearly two years of research and development. This process can achieve an energy density of over 1000Wh/kg and a theoretical load capacity of up to 20000Wh/kg for the negative electrode. The process combines Germany's traditional advantages in high vacuum, fully automatic, nuclear physics, and magnetic levitation fields, and introduces new concepts such as ion printing and porous current collection, enabling the fully automatic continuous production of sodium sulfur batteries in a full vacuum environment with low cost and high production capacity. It is expected to launch equipment prototypes and battery samples by the end of 2023, have mass production capabilities by the end of 2025, and plan to collaborate with industrial funds and battery-related companies to invest in building factories in China.

[Na-ion: HiNa Battery signs 5-year 10GWh supply deal with Korea's VOLTA]

HiNa Battery signed a strategic cooperation agreement with South Korea's VOLTA on Sept 2, advancing from a prior 15MWh storage project to a five-year, 10GWh long-term supply deal. HiNa will lead cell technology and manufacturing, VOLTA will handle system integration and Korean market promotion, and Kwangwoon University will provide R&D and testing support, covering utility, C&I and residential storage scenarios. Since Sept 1, sodium-ion batteries have had their own customs commodity code with a consumption tax exemption through end-2028, making this deal a milestone for China's sodium-ion industry entering global mainstream markets.

Sodium Fluoride (NaF): From Traditional Fluoride Salt to Sodium-Ion Battery "Positioning" Raw Material, Value Reassessment Is Timely [SMM Analysis]

[SMM Analysis: Sodium Fluoride: From Traditional Fluoride Salt to a "Positioning" Raw Material for Sodium-Ion Batteries, Value Revaluation Is Underway] SMM, September 10: Sodium fluoride (NaF) has long been regarded as a niche chemical product for "cavity prevention in toothpaste," with a market size of only 50,000–80,000 mt. However, as the industrialisation of sodium-ion batteries accelerates, NaF, as the core synthetic raw material for NaPF6, is undergoing a round of value revaluation...
