摘要：

A novel type of carbon fibers, obtained by direct chemical activation of stabilized fibers (non-carbonized), is investigated as active electrode material in supercapacitors (SCs). The main advantage of this novel synthetic method is that it avoids the step of carbonization of the stabilized fibers prior to activation, reducing therefore their cost of production. The as-obtained materials exhibit specific capacitances up to 100 F g(-1) in aqueous electrolytes (1.0 M H2SO4), values that are not only higher than those obtained with conventional fibers but also comparable to the capacitances of SCs based on well-established reference materials such as commercial activated carbons (ACs).
