Title Preparation and properties of polyaniline coated capacitor attapulgite and carbonized material

Abstract Supercapacitor is a new energy storage device, it has many distinctive characteristics, like long cycle life and high power density 。 These characteristics made it become the focus of the research in the field of electrochemistry in recentyears。Especiallytheelectrode material which is thought as an important factor to measure the performance of supercapacitor。 Researchers have been exploring the issue is how to reduce the cost of electrode material while improve the performance of electrode material。 Based on the above background, this paper made the following studies:

First, we used inexpensive attapulgite (ATP) as the substrate, and through situ chemical polymerization of aniline synthesis of the polyaniline coated on Attapulgite's surface。 Then followed by high heat treatment of the Polyaniline coated Attapulgite to get nitrogen-doped carbon-coated Attapulgite ATP @ NC- 2。4。 To characterize the morphology, structure and properties of the sample, we use measures of electrochemical measurements and XRD, FTIR, BET, SEM。 The result shows the target product has he gainedandhasexcellent electrochemical properties。
