What are the cathode materials of sodium ion batteries?

The cathode materials of sodium-ion batteries affect the key performance of batteries, such as energy density, cycling performance, and rate characteristics. At present, transition metal oxides, polyanion compounds, and Prussian blue compounds have been reported as cathode materials.

Do cathode materials affect the performance of sodium-ion batteries?

Although the cathode material is the key to the development of sodium-ion batteries, the impact of other factors on the overall battery performance still needs to be taken into account in the commercialization process, and the mechanism should be thoroughly investigated and fed back into the research of new high-performance cathode materials.

What materials can be used to make a sodium ion battery?

Compared with carbon, titanium and organic materials, silicon (Si), tin (Sn), antimony (Sb), germanium (Ge), phosphorus (P) and other elements can achieve alloying reaction with sodium ions, and the theoretical specific capacity is high, and it is a candidate for the anode of the next generation of sodium-ion batteries.

What is a cathode in a lithium ion battery?

In Sodium-ion batteries, as with lithium-ion batteries, the cathode materials are a crucial component. The composition of the cathode material determines the cell voltage and capacity, and thus the energy density.

What are the electrode materials for sodium ion batteries?

Sodium-ion batteries: This article mainly provides a systematic review of electrode materials for sodium-ion batteries. Introduction was made to electrode materials such as prussian blue analogues, transition metal oxides, polyanionic compounds, and carbon based materials.

Are sodium ion batteries compatible with the cathode?

Therefore, their compatibility with the cathode requires due attention and must be addressed in the near future to fabricate a commercially viable sodium-ion battery.
