“…Species transfer in conducting polymer electrodes (CPEs) plays a key role in numerous applications, such as electrochemical sensors [1,2], batteries [3,4] and supercapacitors [5,6]. Up to date, significant attention has been drawn to enhance the ionic transfer/transport and cycling stability of CPEs to devise electronics with effective energy storage capability [7][8][9][10], thereby demanding a thorough understanding of the ion transfer behavior at the CPEs/electrolyte interface.…”

Electrochimica Acta, Elsevier, 2017, 233, pp.262 -273. 10 ABSTRACT:The correlation between electrochemical and viscoelastic properties of electrodeposited dodecylsulfate-doped polypyrrole (PPy-DS) during electrochemical cycling process was described through combining electrochemical quartz-crystal microbalance (EQCM), ac-electrogravimetric characterizations and electroacoustic measurements. As the PPy-DS electrode evolves during the course of consecutive cycling in aqueous NaCl electrolyte, the film exhibits (i) an obvious ion-selective transition from cations to anions in the charge compensation process; (ii) an inferior electrochemical performance accompanied with increased stiffness (increased storage moduli, G´); and (iii) depleted capability of ionic exchange through film/electrolyte interface. PPy-DS conducting polymer electrodes (CPEs) are of interest in energy storage and the relationship between electrochemical and viscoelastic properties during electrochemical cycling process is essential for promoting the performance of these devices. In this perspective, ac-electrogravimetry combined with electroacoustic measurements can be suggested as an alternative method to synchronously probe the electrochemical and mechanical evolution and has the potential to offer a generalized route to study aging mechanism of CPEs.

Asymmetric supercapacitor based on VS₂ nanosheets and activated carbon materials

et al. 2016

View full text Add to dashboard Cite

VS 2 nanosheets as the positive electrode and the activated carbon (AC) as the negative electrode with a 6 M KOH solution as electrolyte were fabricated as an asymmetric supercapacitor. These materials were combined to maximize the specific capacitance and to enlarge the potential window, therefore improving the energy density of the device. A specific capacitance of 155 F g -1 at 1 A g -1 with a maximum energy density as high as 42 Wh kg -1 and a power density of 700 W kg -1 was obtained for the asymmetric supercapacitor within the voltage range of 0 -1.4 V. The supercapacitor also exhibited a good stability with ∼ 99% capacitance retention and no capacitance loss after 5000 cycles at a current density of 2 Ag -1 .
