Abstract:

Abstract: With the rapid development of renewable energy of wind and solar power, the large-scale energy storage system has become more and more important. Lithium-ion batteries have been widely used in portable electronic devices, and are the best choice for the electric vehicles due to their high energy density, long cycle life, high voltage. However, the limited, non-uniform distribution of lithium resources and the high cost would hinder the applications in the field of grid-scale energy storage. Sodium has similar physical and chemical properties with lithium, while sodium resources distribute everywhere around the world. In recent years, room temperature sodium ion battery has attracted widespread attention, particularly for the grid energy storage. Although a large number of sodium-ion battery electrode materials were reported, most of them are still not suitable for practical application. In this review, we will introduce some electrode materials for sodium-ion batteries and point out that in order to realize the commercialization of sodium-ion batteries, we need to explore new cathode and anode materials with high stability in air, high safety, high capacity, high rate capability, superior cycling stability and low cost.

Key words: sodium-ion batteries, cathode materials, anode materials, grid, energy storage
