Because of rich oxygen-containing functional groups and high reactivity, graphene oxide can meed the needs of more active sites and good interfacial compatibility in application fields such as catalysis, nanocomposites and energy storage.

Studies found that GO show good cycle performance when used as an electrode materials in Na-ion batteries.H and O atoms in graphene oxide can effectively prevent the restacking of the sheets, making the spacing of the sheets large enough to allow the rapid intercalation and extraction of sodium ions. It is used as the negative electrode material of the sodium ion battery, and it is found that the charge and discharge times can exceed 1000 times in some kind of the electrolyte.
