Challenge:3. Industrial and distributed energy storage: The demand for industrial and distributed energy storage systems is increasing gradually. These systems are usually used in micro-grids or enterprise parks, and need stable power supply to support production and daily operation. Sodium ion battery can be applied to some remote areas where it is difficult to access the power grid because of its good performance and high cost performance at low temperature.3. Policy support: China Municipal Government attaches great importance to the development of energy storage batteries, and has issued a series of policies and measures to support the research and development and application of new energy storage technologies such as sodium ion batteries. This will provide a strong policy guarantee for the development of Pawa in the field of sodium ion batteries.

4. Environmental protection and sustainability: the production process of sodium ion battery has little impact on the environment, and it is easy to realize recycling, which conforms to the concept of sustainable development.1. Low cost: The abundant sodium resources make the raw material cost of sodium ion batteries much lower than that of lithium ion batteries, which is of great significance for large-scale energy storage and transportation applications.

1. Technical breakthrough: Although sodium ion battery technology has made some progress, it still needs further breakthrough in energy density and cycle life to meet the market demand.Third, the market application opportunities of sodium ion batteries3.
