SUPER CAPACITOR
Construction of Super Capacitor
Activated Carbon: Extremely porous with a very large
surface area. Surface resembles a sponge. Area allows more electrons to be
stored than other conductors.
Activated Carbon ( Activated Charcoal )
Composed of nanometer sized particles covalently bonded together
High porosity (>50% under 100 nm)
Large surface area (400–1000 m²/g)
Aerogel is a low-density solid derived from gel that has had the liquid component replaced with a gas.
Carbon Aerogel
Carbon Nanotubes
Approximately 1/50,000th the width of a human hair
Strongest and stiffest material on earth (>300 X Steal)
Low density Semiconductor
Comparisons
Specific Energy vs Specific Power for Fuel Cells, Batteries, and Capacitors
Applications of Super CapacitorConsumer Electronics• Mobile phones, PDAs • Digital Video & Still Cameras• Solid state drives • e-Book readers & tablet PCs • MP3 players & speakers
Industrial Electronics• Portable POS, PDAs & PCs • Location trackers & RFID tags • Condition monitoring & AMR • Secure radios & security systems • Electronic locks • Electronic Toys
Medical Applications• Non-life-support applications • Pump or solenoid activation for drug delivery • Heating wire to vaporise a drug for
inhalation
Military Applications• Security Equipment’s , Arms , Missiles• Submarines, Nuclear Reactors
Green Solution for Automotive• Stop-Start (warm cranking); Cold cranking;
Regenerative braking & Distributed power support in all vehicles, Railways, etc
• Electric Power steering • Drive-train support in HEV, Electric Vehicles,
Fuel Cell Vehicles & Electric Bikes
Other Green Solutions• Energy harvesting systems: Solar, Vibration;
Wind, Thermal, RF • Smart grid & grid storage • Fuel cell support

Examples of Super Capacitor Capabilities
The CSIRO in Australia [national science agency] has developed the UltraBattery, which combines a super capacitor and a lead acid battery in a single unit
4x longer life cycle, 50% more power, 70% cheaper than batteries used in HEV’s
Hybrid Electric Vehicle
Regenerative Braking Example
1,000kg car travelling at 50 km/h and stopping in 10 secs.
1. Kinetic Energy of the vehicle = 96.45kJoules This is the maximum amount of energy that can be recovered during regenerative braking at 100% efficiency
2. Average Power generated during braking = 9.64 kWatts
3. At 14V Charging Voltage, Charging Current = 689 Amps
• This charging current is too large for a battery to accept, but not for a super capacitor
