| Abstract: | A mesoporous carbon monolith for use in supercapacitors has been prepared from a thermoplastic phenolic resin by curing,molding and activation with CO2.The BET surface area of the as-prepared carbon monolith is 1563m2/g,and the total pore volume is 1.87cm3/g,of which 75.9% is mesoporous in character.The unique microstructure of the carbon monolith enables it to show good electrochemical performance in 1mol/L Et4NBF4/propylene carbonate electrolyte.It shows a capacitance of 108F/g with good rate capability. |
