ABSTRACT:
A process for the formation of alumina containing carbon fiber mats is provided. The process comprises dispersing an alumina precursor solution in the mat, converting the precursor to an insoluble hydroxide precipitate and hydrolizing the precipitate to form alumina nodules dispersed throughout the mat. Also provided is an alumina containing carbon fiber mat comprising carbon fibers and nodules of alumina, which are substantially uniformly dispersed throughout the mat, and a sodium sulfur cell having a sulfur compartment containing such a mat.
