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.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.Iv. Opportunities and challenges of Pawa in the field of sodium electricity

2. Market competition: With the rapid development of the sodium ion battery market, more and more enterprises will enter this field, and the market competition will be more intense. Pawa shares need continuous innovation and research and development to improve product quality and performance in order to stand out in the market.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.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.

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.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.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.
