Titania-graphene anode eletrode paper

Patent ID: 7642 | Patent Number 8,557,441 | Status: Granted

Abstract

We used a commercial titania (Degussa P-25) to prepare titania-graphene composite papers. cationic ammonium surfactants stabilized the titania and graphene in aqueous solutions.the homogeneous composite suspensions containing 80-90 wt% titania were filtered and extra surfactants were removed by thermal treatment at 400C under H2/Ar for 3 h. The composite powder was mixed with 7.0 wt% PTFE to make a paper. Electrochemical test showed steady and high performance (150 mAh/g).
