In today's era of rapid technological development, the energy sector continues to usher in innovation, and solid-state sodium batteries, as a rising star, have attracted much attention.

Solid state sodium batteries are essentially a new type of battery, and compared to traditional sodium ion batteries, their comprehensive performance has achieved a qualitative leap. It cleverly adopts a positive electrode material system similar to sodium ion batteries, which not only lowers the new threshold for material research and development, but also fully utilizes the mature technology and rich experience accumulated in the field of positive electrode materials for sodium ion batteries, making solid-state sodium batteries have a solid foundation at the starting line. More notably, solid-state sodium batteries have successfully overcome a major challenge that has long plagued the development of sodium ion batteries - the ability to stably and efficiently achieve high energy density cycling at room temperature.

This means that solid-state sodium batteries have the potential to perfectly adapt to both the power supply needs of daily electronic devices and the power guarantee for the long range of future electric vehicles, greatly expanding the boundaries of their application scenarios.

At present, major battery manufacturers and technology giants around the world are gearing up to lay out the highly potential field of solid-state sodium batteries, striving to seize the opportunity in the ever-changing market competition in the future.

At the beginning of its establishment, Na Yuan New Materials conducted research on solid-state battery materials and designed membrane structures, with relevant patentsSolid state electrolytes and their preparation methods and applications、Solid state electrolyte membrane and its preparation method, and solid-state lithium batteryObtained national authorization. This innovative achievement marks the profound foundation and forward-looking vision of Sodium Far East in the field of solid-state battery technology.

Solid state sodium ion battery technology is similar to solid-state lithium battery technology, and its core points are as follows:

Based on the above core points, selecting suitable positive electrode materials and solid sodium ion electrolyte materials for solid-state sodium ion batteries, matching the positive electrode materials with the solid electrolyte materials, using coating technology, or fusing the solid electrolyte materials into a film and optimizing the battery structure interface to improve the internal ion migration kinetics performance of the battery is the key to solving the above problems, that is, the key to the ion transport problem at the solid solid interface.

For the positive electrode material of solid-state sodium ion batteries, Na Yuan New Materials adopts a unique material framework structure design and high entropy stacking principle to expand the ion tunnel for sodium ion migration, and designs a positive electrode material with high specific capacity and high voltage bearing capacity. It has been tested that the material exhibits a characteristic capacity of over 200mAh/g at high voltages above 4.3V, and has good cycling performance.

For solid sodium ion electrolyte materials, Sodium Yuan New Materials has developed a solid electrolyte material with wider tunneling effect and higher sodium ion migration force based on the research and development foundation of NASICON series materials. The material can be used as powder or slurry, and can be perfectly integrated with membrane structure to achieve the best working effect of solid electrolyte.

Na Yuan New Materials possesses the development capability of special sodium positive electrode materials and the optimization capability of sodium solid electrolytes, with dual side driving and energy storage capabilities. These natural advantages lay a good foundation for the design of high specific capacity long cycle solid-state sodium ion batteries by Na Yuan New Materials, and will also help Na Yuan New Materials achieve higher industrialization goals.
