FIELD: nanoporous materials.
SUBSTANCE: group of inventions relates to nanoporous carbon frameworks or structures and, in particular, to carbon aerogels, and their manufacture, and their use. Embodiments include a cathode material in a lithium air battery where the cathode is formed from a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel contains pores that improve the oxygen transfer properties of the electrolyte solution and improve the formation of lithium peroxide on the surface and/or in the pores of the carbon aerogel. The cathode and underlying carbon aerogel provide optimum properties for lithium air battery applications.
EFFECT: improved performance of the electrode.
