In 2023, the industrialization of sodium power will usher in key nodes. Based on the differentiation of positive pole materials, the current sodium power has developed into three major technical routes: layered oxides, polycotic compounds, and Prussian compounds.
Due to the advantages and disadvantages of the three major technology routes, and the market demand and response speed are different, the industrialization progress has also been different.
Specifically, layered oxide energy density density and magnification performance, etc., performed the best in the three technical routes, and has taken the lead in completing the industrialization.
The stability of polycotic compounds and high electrochemical stability, and has the longest theoretical cycle life, the application prospects such as low -speed vehicles and energy storage are broad, and the industrialization speed is faster.
In terms of Prussian compounds, due to the production of toxic gases after preparing crystallization and heat loss, the current industrialization progress is relatively slow.
Layer -shaped oxide is currently the mainstream technical route of sodium electricity. The structural ratio is a ternary material in lithium battery, which is relatively high than the capacity. It can solve other elements. Difficulty, and its process process is similar to the ternary material, and it is the first to complete industrialization.
Since the beginning of 2023, many companies have officially officially promoted the application of laminar sodium oxide appliances.
However, relevant people in the industry analyzed that if the price of lithium ore further reduced to less than 300,000 yuan/ton, the cost advantage of layers of oxides will be difficult to reflect.
The agglomerate compound has a solid and open three-dimensional network structure. The analogy is lithium iron phosphate in the lithium battery material. Its gram capacity is 80-130 mAh/g. life.
However, due to poor conductivity and low energy density of polycinity ions, the cost of mixing routes is high and the energy density performance of the railway route is poor. It is currently mainly used as a reserve plan.
Due to the lowest cost among the three materials, the price of Jugin ions is the lowest, and the price of lithium ore has continued to decline or has an advantage. The application side, the material has the longest theoretical cycle life, and is more suitable for the energy storage market.
Not only that, the technical route of polycotic ions includes sodium phosphate, sodium manganese phosphate, and iron sulfate.
The Prussian compound is a typical cubic crystal structure. All its metal ions are located at the top angle of the cube. It has a large tunnel structure and allows sodium ions to be freely embedded and dehydrated. 90-140 mah/g.
However, due to the difficulty of crystallizing water control during mass production, the current stability of the Prussian compound is poor, the current stability is poor, the process control needs to be further matured, and the industrialization progress will be simultaneously improved with the research progress.
In general, the road of layer -shaped sodium oxide electrical electricity is relatively clear, there are many enterprises in the bureau, the production capacity planning in 2023 is large, and the landing application is wider; The market demand for energy storage, etc. is greater; the industrialization of Prussian compound industrialization is relatively slow.
However, with the breakthroughs of the technologies, processes, processes, and more landing applications of Julin ionic compounds, Prussian compound materials, and the emergence of more landing applications, the industrialization process will accelerate.
