Standard pen ink is the surprise component in a flexible carbon fibre supercapacitor which can be bent in a full circle with barely any loss of performance.
Supercapacitors are devices that can unleash large amounts of charge very quickly and are useful in situations where electricity is required to charge or discharge fast: to balance loads on power grids, for instance.
Just a few millimetres in diameter, the new ink-based supercapacitor outdoes the performance of other carbon fibre-based devices, and can hold up to 10 times more charge. _________________ it classes
