Energy storage principle of polyaniline

Can polyaniline be used as a supercapacitor?

Polyaniline (PANi) as one kind of conducting polymers has been playing a great role in the energy storage and conversion devices besides carbonaceous materials and metallic compounds. Due to high specific capacitance, high flexibility and low cost, PANi has shown great potential in supercapacitor. It alone can be used in fabricating an electrode.

Why is polyaniline a good solid support for metal nanoparticles?

Conducting polymers (CPs) have attracted interest as solid supports for metal nanoparticles (MNPs) to improve their stability. In particular, polyaniline (PANI) has gained popularity due to its low cost, high electrical conductivity, stability and ease of preparation.

Why is conductive polyaniline a good catalyst?

The conductive polyaniline is favorable for HER and HOR due to its sufficient protonated sites. Platinum (Pt) is a precious metal with excellent HER and ORR activity . In order to increase the utilization of Pt catalysts, PANi was used as a supporting matrix for Pt dispersion.

Is Pani a promising material for energy storage/conversion?

Besides, PANi derived nitrogen-doped carbon materials, which have been widely employed as carbon based electrodes/catalysts, are also involved in this review. PANi as a promising material for energy storage/conversion is deserved for intensive study and further development. 1. Introduction

Why is polyaniline a good conductor of Li-rich cathode materials?

Conducting polyaniline is an excellent material to make surface modification of these Li-rich cathode materials, resulting in improved conductivity and stability .

How many articles are there in polyaniline supercapacitor synthesis?

More than 170 journal articles have been reviewed. Different polyaniline supercapacitor electrodes design, synthesis processes, mechanism and applications is studied. Doping with metal, carbon nanotubes, graphene, and activated carbon results into high performance supercapacitors.
