Template Synthesis of Mesoporous Carbon Materials for Electrochemical Capacitors

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