Template Synthesis of Mesoporous Carbon Materials for Electrochemical Capacitors

The effect of AlOOH endo-template on the porous structure, electrical conductivity and electrochemical properties of lactose-derived carbon materials was investigated. It was found that a carbon material with specific surface of 1707 m²/g and total pore volume of 1.546 cm³/g could be obtained when the mass ratio of C:AlOOH is 1:1. Electrochemical capacitors, formed on the base of the synthesized samples, have a large range of the specific capacity (66–170 F/g) at a discharge current of 10 mA. The developed mesoporous structure of the carbon materials synthesized via the template method allows charge/discharge electrochemical capacitors at currents up to 200 mA, providing specific capacity of 121 F/g.
