by chronopotentiometry. Figs.3(a) and (b) show the charge- discharge curves of PLi/PLi and PLi/C supercapacitors in the range of 0-1.0 V and 0-2.5 V, respectively. In Fig.3(a), the charge-discharge curves of both......
are confirmed by GITT technology [15-17]. GITT is an effective way to investigate the chemical diffusion coefficient, which is based on chronopotentiometry under an approximate thermodynamic......
cycling voltammetry (CV), potentiodynamic polarization curves, chrono- amperometry and chronopotentiometry with an EG&G PAR 273A potentiostat/galvanostat controlled by Power Suite software......
and chronopotentiometry test. As shown in Figure 3(e), there is no obvious deviation of current density after 1000 cycle sweeps even in the high overpotential region. Under the constant voltage (Figure 3(f)), the current......
