Over the last several decades, the major energy source has been fossil fuels, which are non-renewable, finite, and environmentally hazardous. To solve out these problems, clean and sustainable energy systems have been studied such as solar cells, fuel cells, and rechargeable batteries. While Li-ion rechargeable batteries are currently dominant energy storage systems in the market powering numerous portable electric devices, the commonly used electrode materials, such as LiCoO2 and LiMn2O4, are prepared from the limited mineral resources. Especially, the amount of lithium resources is not enough to supply a demand for the industry of electric vehicles. Therefore, recently, a sodium ion battery is regarded as an intriguing candidate of a next generation battery due to the non-toxicity and potential cost advantages coming from its natural abundance. Compared to wide attention on lithium intercalation to the layered compounds, limited studies have been reported on the sodium intercalation becasue of its slow kinetics by relatively large effective ionic radus (102 pm) compare to lithium ion (76 pm). Herein, we introduce various new electrode materials for soium ion battreies. The material characterization and electrochemical performance of those materials are examined.
