Preparation of controlled porosity carbon aerogels for energy storage in rechargeable lithium oxygen batteries [PDF]
, 2009 Porous carbon aerogels are prepared by polycondensation of resorcinol and formaldehyde catalyzed by sodium carbonate followed by carbonization of the resultant aerogels in an inert atmosphere. Pore structure of carbon aerogels is adjusted by changing the
