We have successfully employed a charge transfer mechanism to convert carbon nanotube (CNT) powder into CNT flexible membrane with no binder. We have demonstrated the use of the CNT membranes as electrode in a stacked bipolar solid-state capacitor using grafoil as current collector that showed 80% capacitance retention over …

The energy efficiency of this VRB with N0.7P0.3 membrane was 85.1% at a current density of 50 mA cm − 2, which was superior to that of a recast Nafion (r-Nafion) membrane (80.5%). Self-discharge tests showed that the decay of open-circuit potential of the N0.7P0.3 membrane was much lower than that of the r-Nafion membrane.
