Sodium-ion battery energy storage main body

Are sodium ion batteries a viable alternative energy storage system?

Sodium is abundant on Earth and has similar chemical properties to lithium, thus sodium-ion batteries (SIBs) have been considered as one of the most promising alternative energy storage systems to lithium-ion batteries (LIBs).

What are sodium-ion batteries?

As such, sodium-ion batteries (NIBs) have been touted as an attractive storage technology due to their elemental abundance, promising electrochemical performance and environmentally benign nature.

What materials can be used for a sodium ion battery?

These range from high-temperature air electrodes to new layered oxides, polyanion-based materials, carbons and other insertion materials for sodium-ion batteries, many of which hold promise for future sodium-based energy storage applications.

What are high-rate and long-life sodium-ion batteries based on?

Zhan, R.M., Zhang, Y.Q., Chen, H., et al.: High-rate and long-life sodium-ion batteries based on sponge-like three-dimensional porous Na-rich ferric pyrophosphate cathode material. ACS Appl. Mater.

Are Na and Na-ion batteries suitable for stationary energy storage?

In light of possible concerns over rising lithium costs in the future, Na and Na-ion batteries have re-emerged as candidates for medium and large-scale stationary energy storage, especially as a result of heightened interest in renewable energy sources that provide intermittent power which needs to be load-levelled.

What is the future of sodium battery materials?

Moreover, new developments in sodium battery materials have enabled the adoption of high-voltage and high-capacity cathodes free of rare earth elements such as Li, Co, Ni, offering pathways for low-cost NIBs that match their lithium counterparts in energy density while serving the needs for large-scale grid energy storage.
