Electrolyte selection for supercapacitive devices: a critical review. Nanoscale Advances, 1(10), 3807–3835. https://doi.org/10.1039/c9na00374f2516-0230http://hdl.handle.net/1880/111697https://dx.doi.org/10.11575/PRISM/37616Electrolytes are one of the vital constituents of electrochemical energy storage devices and their physical and chemical properties play an important role in these devices' performance, including capacity, power density, rate performance, cyclability and safety. This article reviews the current state of understanding of the electrode–electrolyte interaction in supercapacitors and battery–supercapacitor hybrid devices. The article discusses factors that affect the overall performance of the devices such as the ionic conductivity, mobility, diffusion coefficient, radius of bare and hydrated spheres, ion solvation, viscosity, dielectric constant, electrochemical stability, thermal stability and dispersion interaction. The requirements needed to design better electrolytes and the challenges that still need to be addressed for building better supercapacitive devices for the competitive energy storage market have also been highlighted.enUnless otherwise indicated, this material is protected by copyright and has been made available with authorization from the copyright owner.
