Enhancing 5 V capacitor performance by adding single walled carbon nanotubes into an ionic liquid electrolyte

A nanofluid electrolyte of single walled carbon nanotubes and ionic liquids can enhance the energy density, power density and cycling stability of nanotube electrodes with a surface area of 600 m2 g−1 at 5 V, by decreasing internal resistance from the bulk phase of ILs to the electrolyte/electrode interface.
