Abstract

Ionic liquids are organic salts with melting points generally below 100 °C. They are attracting wide attention and are used as electrolytes in electrochemical devices, such as fuel cells, lithium-ion batteries, dye-sensitized solar cells, supercapacitors and light-emitting electrochemical cells, due to their negligible vapor pressure, high ionic conductivity and wide electrochemical window. This perspective article highlights the applications of ionic liquid- or poly(ionic liquid)-based electrolytes in fuel cells, dye-sensitized solar cells and supercapacitors. © 2013 Society of Chemical Industry
