More studies are focused on VO 2 (B) nanostructures which displayed different energy storage behavior than the bulk VO 2.

Can a 3D spongy VO 2 composite be used as Zn 2+ storage material?

A 3D spongy VO 2 composite with enriched oxygen vacancies and graphene-modified heterointerfaces (O d -VO 2 -rG) is successfully prepared as Zn 2+ storage material. Fast and stable Zn 2+ (de)intercalation as well as reversible Zn 2+ adsorption/desorption can be realized in the designed O d -VO 2 -rG simultaneously.

What is a spongy 3D VO 2 composite with enriched oxygen vacancies?

A synergistic strategy by subtly combining deficiency and heterojunction engineering is developed to construct a spongy 3D VO 2 composite with enriched oxygen vacancies and graphene-modified heterointerface (O d -VO 2 -rG).

How are VO 2 electrodes fabricated?

To compare with freestanding RGO/VO 2 composite films, conventional VO 2 electrodes were fabricated by mixing pure VO 2 powder, super P and polymer binder into homogeneous slurries and coating them onto stainless steel meshes.

Does VO 2 / rgo-2 composite have better electrochemical activity?

The maximum specific capacitance of 353 F g −1 was obtained at 1 A g −1 for VO 2 /rGO-2 composite compared to 80 and 248 F g −1 for rGO and VO 2 (B) nanobelts, respectively. This indicated that VO 2 /rGO composites had better electrochemical activity, in consistent with CV results.
