Sodium Battery: Solid-state sodium-sulfur batteries with an energy density of 1000Wh/kg will be mass-produced by 2025. At the "Invest in China" Germany special event hosted by the Ministry of Commerce of China, a German expert team has developed a full set of high-performance and high-safety solid-state sodium-sulfur batteries with an automatic continuous production process over the past two years. The battery can achieve an energy density of over 1000Wh/kg and a theoretical loading capacity of up to 20000Wh/kg. This technology combines Germany's traditional advantages in high vacuum, automatic, nuclear physics, and magnetic levitation fields, and introduces new concepts such as ion printing and porous current collection, enabling the automatic continuous production of sodium-sulfur batteries in a fully vacuum environment with low cost and high yield. It is expected that equipment prototypes and battery samples will be available by the end of 2023, with mass production capability by the end of 2025. The project plans to collaborate with industry funds and battery-related companies and intends to invest in establishing a factory in China.
