Iv. Opportunities and challenges of Pawa in the field of sodium electricity1. 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.

2. Transportation field: In the transportation field, sodium ion batteries can be used as a supplement to lithium ion batteries and applied to some new energy vehicles, low-speed electric vehicles, two-wheeled vehicles and other fields with low endurance requirements. In addition, sodium ion batteries can also be used in mining areas, construction machinery and other scenes to replace traditional diesel engines and reduce the problems of air pollution and corrosion of equipment.Second, the advantages of sodium ion batteries over lithium ion batteries1. Energy storage field: The application prospect of sodium ion battery in energy storage field is broad. With the rapid development of renewable energy, the demand for energy storage technology in power grid is increasing. Sodium ion battery has obvious advantages in power grid energy storage and renewable energy storage because of its low cost, high safety and strong temperature adaptability.

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.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.
