Abstract Tremendous efforts have been dedicated to developing high-performance energy storage devices based on the micro- or nano-manipulation of novel carbon electrodes, as certain nanocarbons are perceived to have advantages such as high specific surface areas, superior electric conductivities, excellent mechanical properties and so on. In typical electrochemical electrodes, ions are intercalated/deintercalated into/from the bulk (for batteries) or adsorbed/desorbed on/from the surface (for electrochemical capacitors). Fast ionic transport, significantly determined by ionic channels in active electrodes or supporting materials, is a prerequisite for the efficient energy storage with carbons. In this report, we summarize recent design strategies for ionic channels in novel carbons and give comments on the promising features based on those carbons towards tailorable ionic channels.

The ability to achieve high surface areas with nanomaterials brought several advancements in energy storage devices and their applications in different industries. Supercapacitors, a new generation of energy storage devises, have quick charge and discharge abilities, and hold as much energy as batteries and other chemical storage devices. The present study focuses on the effects of carbon nanotubes (CNTs) inclusions in polyvinyl alcohol (PVA) electrolytes for the improved capacitance values, which may affect the lifetime, charge holding, and charging and discharging rates of the graphene nanoflake-based supercapacitors. In this research, various supercapacitors were constructed using the reduced graphene oxide nanoflakes, PVA and PVA incorporated with CNTs, and the best candidates were selected for the future considerations. The test results showed that the CNT concentrations of 0.1–1.0wt% in PVA enhanced the capacitance (charge holding capacity) and reduced the internal resistance of the electrolytes significantly. This study may open up new possibilities for the supercapacitors and other energy storage devices currently under developments.

Aim: Aim of this study is to find the effect of the current collector in the performance of flexible energy storage devices based on surface modified organic-inorganic composite. Objective: As a part of our pursuit to develop flexible supercapacitive electrodes, we recently reported the fabrication of an electrode from an organic-inorganic composite slurry of surface functionalized fullerene and nickel hydroxide coated onto a copper sheet substrate using simple doctor blade method. We reported that the electrodes deliver specific energy and specific power of 661.5 Wh/kg and 8.8 KW/kg, respectively, and a specific capacitance of 675 Fg−1, which showed excellent cycling stabilities. In an effort to search for various combinatorial combinations of the composite and the substrate, in lieu of copper, in the present study, we incorporate nickel sheet as the current collector. Methods: The structure and composition of the binder-free, flexible super capacitive electrodes were characterized using XRD, TEM, FTIR, XPS, BET, Raman Spectroscopy, and their electrochemical properties were characterized using cyclic voltammetry, galvanostatic charge-discharge measurements, chronoamperommetry and impedance spectroscopy. Result: The as-prepared films stuck readily onto the substrate without the need of any binder material, exhibited remarkable flexibility, and were proven to be crack-free when subjected to repeated bending and twisting. The developed flexible super capacitive electrodes deliver a specific capacitance of 296 F g−1, maximum energy density of 82.2 Wh kg−1, and a maximum power density of 1056 W kg−1. The device retains 91.2 % of its capacitance when subjected to 1000 charge-discharge cycles. Conclusion: Our observations indicate that copper is the better choice as the current collector, which can be ascribed to the better electrical conductivity of copper compared to nickel. We conclude that the poor electrical conductivity of nickel sheet compared to copper substrate make the bottleneck for the performance of electrodes made using nickel substrate. To recapitulate, judicious choice of a current collector with high electrical conductivity along with a suitable surface modification strategy to form a composite in an amorphous form that forms smooth slurry are vital to the fabrication of binder-free, flexible supercapacitive devices.
