This template can be used as a starter file for presenting training materials in a group setting.SectionsRight-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors.NotesUse the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)Coordinated colors Pay particular attention to the graphs, charts, and text boxes.Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.Graphics, tables, and graphsKeep it simple: If possible, use consistent, non-distracting styles and colors.Label all graphs and tables.
Give a brief overview of the presentation. Describe the major focus of the presentation and why it is important.Introduce each of the major topics.To provide a road map for the audience, you can repeat this Overview slide throughout the presentation, highlighting the particular topic you will discuss next.
This is another option for an Overview slides using transitions.

Supercapacitors are electrochemical
devices with following features:
High energy density.
High power density.
• The first supercapacitor based on double
layer mechanism was developed in 1957 by
General Electric using porous electrode.
• Standard Oil Company Cleveland Ohio
rediscovered this effect in 1966 & gave
licensing to NEC in 1978 for market
It consists of following
• Current collector: Metal
contacts are used as
current collectors .
Polarized electrode: Highly activated
carbon is used as electrode because of
• It is highly porous
• It has extraordinarily high specific surface
• It has good conductivity
• High temperature and chemical stability
• Corrosion resistant
It contains dissolved and solvated ions that
migrate to and from the electrodes during
charge and discharge respectively.
Electrolytes are of two types:
• Water soluble
• Water insoluble
It acts as mechanical separation between two
It must provide electronic insulation between the
electrode of opposite polarization
It must support ionic conduction
from one electrode to another.
• Used in Diesel engine start up in submarines
• Used to recover braking energy in HEV &
modern trains and deliver the same during
• Can be used in f &V control in power systems
• Used as backup energy source for GPS guided
