Carbon nano materials based composites for energy storage.

The development of human industrial technology has increased the requirement for electric energy. At present, the rapid development of various smart devices has led to an increasing demand for high-performance batteries. The emergence of various wearable devices has led to a need for flexible electrodes. Aerogels and paper, as two good flexible porous materials, have attracted many scholarly studies in recent years. Combining carbon materials, which have excellent electrochemical properties, with aerogel and paper can result in flexible electrodes with good performance. This research presents a series of aerogel and carbon paper samples prepared using three different production processes. For the aerogel samples, the effects of graphene addition and manufacturing route were investigated. The study resulted in a recommended material and process to produce a porous aerogel sample with high electrochemical cycle stability. For carbon paper samples, the relationship between variables such as surfactant, paper, conductive material and the sample properties was examined. Initial work indicates that carbon paper manufacturing routes are simpler than others reported elsewhere and provide materials that have electrochemical properties with potential for use as electrodes in supercapacitors and other energy storage devices. Of course, cost and environmental protection have also been considered in this project.
