BY
H.SAHITHI VERMA

2. INTRODUCTION
WHAT IS SUPERCAPACITOR?
STORAGE DEVICE
CONSTRUCTIONAL FEATURES WITH
RESPECT TO USUAL CAPACITORS
CHARGING ABILITY
RANGE
ENERGY DENSITY

3. INTERNAL STRUCTURE
 3 LAYERS
2 POROUS CARBON ELECTRODE
ELECTROLYTE

4. CLASSIFICATION OF SUPERCAPACITORS

5. CONSTRUCTIONAL FEATURES
MADE OF ALUMINUM
COATED WITH 100MM THICK
ACTIVATION OF CARBON
DOESN’T REACT CHEMICALLY

6. MODERN SUPERCAPACITOR
 IMPLEMENTATION OF
NANOTECHNOLOGY
 REPLACEMENT OF ACTIVE CARBON
USING NANOTUBES
 SIZE OF NANOTUBE IS 5NM AND 100µM
 NANOTUBES ARE VERTUCALLY GROWN

7. FEATURES
 HIGH RATE OF CHARGING AND
DISCHARGING
 GOOD REVERSIBILITY
 LOW TOXICITY OF MATERIALS USED
 HIGH CYCLE EFFICIENCY(95% OR
MORE)
 HIGH STORAGE CAPACITY

8. ADVANTAGES
HIGH POWER DENSITY
LOW IMPEDANCE
CAN NOT BE OVERCHARGED
SIMPLE CHARGING METHODS

9. DISADVANTAGES
 LIMITED USE OF FULL ENERGY
SPECTURM
 LOW ENERGY DENSITY
 LOW VOLTAGE
 HIGH SELF DISCHARGE
 MANUAL CONTROL

10. APPLICATIONS
 MILITARY PROJECT
 STARTING DIESEL TRUCK
 RAIL ROAD LOCOMOTIVES
 ELECTRIC/HYBRID VEHICLIES FOR
TRANSIENT LOAD LEVELING
 REGENERATING THE ENERGY OF BRACKING
 REPLACEMENT FOR BATTERIES
 FUNCTION WELL IN LOW TEMPERTURE

11. TECHNOLOGY
 CARBON NANOTUBES AND CERTAIN
CONDUCTIVE POLYMERS OR CARBON
AEROGELS ARE PRACTICAL FOR
SUPERCAPACTIORS
 CARBON NANOTUBES HAVE EXCELLENT
NANOPOROSITY PROPERTIES ALLOWING
TINY SPACES FOR THE POLYMER TO SIT IN
THE TUBE AND ACT AS A DIELECTRIC

12. CONCLUSION
CAPACITANCE IS 2.6KF
WE CAN USE SUPERCAPACITIORS
AS BATTERIES , NANTOXIC AND
ECO-FRIENDLY
