Active materials for negative electrodes of sodium batteries

What are the negative electrode materials for Na-ion batteries?

This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes.

Which materials are used for a negative electrode for sodium ion?

Abstract Carbon materials, including graphite, hard carbon, soft carbon, graphene, and carbon nanotubes, are widely used as high-performance negative electrodes for sodium-ion and potassium-ion bat...

Can non-graphitic carbons be used for negative electrodes of Na-ion batteries?

Graphite ineffectiveness in sodium storage has induced extensive research on non-graphitic carbons as high-performance active materials for negative electrodes of Na-ion batteries.

How to choose a negative electrode material for sodium storage?

The ideal negative electrode material can be better designed via different preparation means, such as adding the introduction of active sites or preparing synthetic materials. As researchers continue to explore the mechanism and optimize the preparation method, the subsequent HC will be even better in sodium storage. 2.2. Soft Carbon Materials

Is carbon black a promising electrode material for sodium ion batteries?

Alcantara, R., Jimenez-Mateos, J.M., Lavela, P., et al.: Carbon black: a promising electrode material for sodium-ion batteries. Electrochem.

What makes a good negative electrode material?

The amorphous state and large layer spacing of hard carbon materials enable effective Na + embedding and release, making them a better choice for anode materials. The ideal negative electrode material can be better designed via different preparation means, such as adding the introduction of active sites or preparing synthetic materials.
