High temperature oxygen treated carbon aerogels

Patent ·
OSTI ID:1459575
; ; ;
Disclosed here is a method for increasing the hydrophilicity of a carbon aerogel, comprising heating the carbon aerogels under air or a gas having a higher concentration of oxygen than air at a temperature of about 200.degree.-500.degree. C. to obtain an activated carbon aerogel. Also disclosed include an activated carbon aerogel obtained by the method, an electrode comprising the activated carbon aerogel, and a supercapacitor or capacitive deionization device comprising the electrode.
