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.
