2. Transportation field: Although the energy density of sodium ion batteries is relatively low, with the continuous development of technology, they may be applied in some new energy vehicles with low endurance requirements, such as small electric vehicles and urban scooters. In addition, sodium ion batteries can also be used as a supplement to lithium ion batteries, which can be used in the fields of two-wheeled vehicles, tricycles and so on.The above advantages of sodium ion battery provide broad market opportunities for its application in many fields:

1. Rich resources and low cost: Sodium is one of the most abundant elements in the earth's crust, and its abundance is much higher than that of lithium, so sodium ion batteries have obvious advantages in raw material cost. This feature makes sodium ion battery more economical in large-scale application and helps to promote the rapid development of its market.Advantages of sodium ion batteryCompared with lithium ion batteries, sodium ion batteries have many obvious advantages:

2. High safety: Sodium ion batteries perform well in safety tests such as overcharge, overdischarge and short circuit, and are not easy to catch fire and explode. This characteristic makes sodium ion batteries have greater advantages in application scenarios that require high safety.4. Good rate performance: The sodium ion battery has excellent rate performance and can be charged and discharged quickly in a short time. This feature makes sodium ion batteries more competitive in application scenarios that require rapid response.Compared with lithium ion batteries, sodium ion batteries have many obvious advantages:
