Along with the cooperation of Zhongke Hai sodium has planned the world's first 5GWh sodium ion battery mass production line, 1GWh sodium ion battery PACK capacity and annual output of 2000 tons of cathode + 2000 tons of anode materials project, while Ningde launched the first generation of sodium ion battery, the industry companies such as sodium innovation energy, star sodium power, Hunan cubic new energy, Duoduo and other companies have entered the sodium battery field, Rongbai technology, Dansheng technology, Zhenhua new material, Tianzhi material (002709) and other material manufacturers have also laid out, the industrialization has accelerated significantly, Rongbai Technology, Dansheng Technology, Zhenhua New Material, Tianchi Material (002709) and other material manufacturers have also laid out, industrialization is significantly accelerated. Guoxin Securities expects the global demand for sodium batteries to reach 23GWh in 2025, with a market size of over 13.8 billion yuan.

　　So it seems that the demand for sodium ion batteries to produce with the current level of technology, the market size is not very large. This mainly stems from the sodium ion inherent defects, sodium ion batteries are now the overall cycle life of about 2000 times, slightly worse than the performance of lithium iron phosphate batteries, compared to some of the cycle life of more than 5000 times in the field of energy storage lithium iron phosphate batteries are still a certain gap. Due to high downstream demand, and lithium resources are mostly distributed abroad, the current lithium hydroxide, lithium carbonate prices are still at a high level, the cost advantage of sodium resources is more significant, if the future price of lithium resources fell sharply, sodium battery cost performance will decline, combined with cycle life is less than lithium iron phosphate, or will be hampered by the development.

　　And according to the disclosed data, sodium innovation energy sodium ion battery energy density of more than 130Wh/kg, cubic new energy products energy density of 140Wh/kg, in the sodium products of the sea energy density of 145Wh/kg, there is still room for further optimization.

　　To sum up, sodium electricity technology gradually mature, 23 years of industrialization year, is expected to achieve accelerated penetration, Dongwu securities bullish sodium electricity industry chain prospects.
