2. High safety: The sodium ion battery has an ultra-wide working temperature range of -40℃-80℃, and it is not easy to get out of control even at high temperature, so its safety is higher.2. Industrial chain coordination: Pawa shares can establish close cooperative relations with upstream and downstream enterprises to jointly promote the development and improvement of the industrial chain of sodium ion batteries and improve market competitiveness.Opportunity:

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.Second, the advantages of sodium ion batteries over lithium ion batteries3. 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.

First, the development prospect of sodium ion batteriesChallenge:3. Strong temperature adaptability: The performance of sodium ion battery is excellent in low temperature environment, even in the low temperature environment of -20℃, its capacity retention rate can still reach above 88%, which makes sodium ion battery have obvious advantages in energy storage application in cold regions.
