The strong, flexible fibres, which can be tied in knots or woven into conductive mats, could be the key to deploying graphene in real-world devices such as flexible batteries. Link to Original Source
I have yet to see any problem, however complicated, which, when
you looked at it in the right way, did not become still more complicated.
