Under different scan rates (5–100 mVs−1), each CV curve shows a pair of redox peaks, representing the pseudocapacitive behavior. The specific capacitance is mostly linked with the quasi-reversible electron-transfer kinetics originating from Ni2+/Ni3+ and Co2+/Co3+ redox reactions and ...
After being cycled at 5 C Figure 8. Charge‐discharge characteristics of cells containing various separators at first cycle. The cycle performances of the cells at different C‐rates are shown in Figure 9. ...
High specific capacity values were delivered by the batteries when were cycled under both low and high current rates. The good stability in the extended cycling together with the excellent coulombic efficiency allows us to conclude that this biomass-derived carbon could be a sustainable source of ...
Finally, the second stage is equilibrium adsorption, corresponding to low adsorption rates and kd2 values. However, in the linear fitting, the straight line does not pass through the origin, indicating that intra-particle diffusion is not the only factor affecting the adsorption rate of mercury. ...
