A new a hybrid graphene material may be useful for flexible supercapacitors

Researchers from the University of Texas and the University of Science and Technology of China developed a new graphene-like material (called VOPO₄) that can be useful as a working electrode of flexible supercapacitors together with graphene.

VOPO₄, which is less than 6 atoms, was developed by using a 2-2-propanol-assisted ultrasonic method to exfoliate bulk VOPO₄·2H₂O into VOPO₄ nanosheets. The researchers created a hybrid graphene-VOPO₄ sheet that achieves both high planar conductivity and better electrochemical performance compared to pure graphene.
