carbon nanotube in supercapacitors
DESCRIPTION
Carbon nanotubes in Supercapacitors It is a preview of my future work on carbon nanotubesTRANSCRIPT
WHATWHYHOW
SUPER CAPACITOR
An Electrochemical capacitors or ultra capacitors, which have very high capacitance compared to conventional capacitors and has high values of energy density and power density
TYPES OF SUPER CAPACITORS
Super capacitor V/S Battery
High power density High energy density
How it works????????????????????
•Carbon nanotubes
•One atom thick sheet of graphite rolled up into a cylinder with diameter in the order of nano scale.
•SP2HYBRIDISED
•Aspect ratio 132000000:1
•electric current density- 4 × 109 A/cm2
•Thermal conductivity-3500 W·m−1·K−1
Thermal Chemical vapour deposition
•Precursors
Paraffin wax (C31H64) Cow dung Benzene(C6H5)
Substrate: Ni FoilCarrier gas: Argon
Cyclic Voltammetry (CV) is a widely used technique in electrochemistry. Early in a development project, CV yields basic information about a capacitive electrochemical cell, including:•Voltage window•Capacitance•Cycle life
•To be continued with
•Outcomes of the synthesis and relevent results
•Characterisation
•Practical applications
