| Dependences of maximum energy conversion efficiency ( ε max) of the surface-charged CNT on effective surface charge density. The nanotube used in the nanofluidic battery has a radius of 1.085 nm, and 1-M KCl is used here as the electrolyte. The number of surface charges varies from 0 to 12 e. The efficiency calculated with the slip length of the surface-charged CNT (shown in Fig. 4(b) ) is much lower than that predicted with the slip length of the uncharged ones (about 110 nm), based on our MD simulations. |
