  1. Electronic Energy Storage Units:Powering Our Future Dr. Rebman By: Kaelen McCrane

  2. What is an EESU? • A more efficient, powerful battery • Converts stored Chemical Energy into Electrical Energy • Makes use of portable electricity available for greater number of applications

  3. How Does an EESU Work? • Simple battery is composed of a number of voltaic cells • Each voltaic cell is a combination of two half-cells • Cathode/Anode • Connected by an electrolyte

  4. How Does an EESU Work? • Because of different charges between electrodes, there is a difference in EMF • Voltage is the measurement of this force

  5. Basic Battery Types • Primary (Non-Rechargeable) • Secondary (Rechargeable)

  6. Development of EESUs • First evidence of batteries dates back to 190 BC in Baghdad. • Iron rod surrounded by copper, encased in a pot. • Produced 1.5-2 volts

  7. Development of EESUs • Alessandro Volta, 1800 published specifications for his “pile” batteries. • Stacked Silver, Zinc, and salt.

  8. Development of EESUs • 1949 modern Alkaline battery created by Lew Urry, Eveready. • Lithium Ion battery introduced by Sony in 1991.

  9. Modern Advances of the EESU • Organic radical battery, NEC corporation. • Super thin, 300 microns • Charge in less than 30 seconds • No heavy metals

  10. Modern Advances of the EESU • Ultra-capacitors, developed by EEStor and Maxwell Technologies. • BOOSTCAP ultra-capacitors up to 10x power and longevity of traditional alkaline batteries.

  11. Modern Advances of the EESU • EEStor’s ultra-capacitors combine Barium Titanate, Aluminum Oxide, and glass. • Previous super-capacitors were impractical, only about .02MJ/kg. • EEStor ultra-capacitors expected up to 2.5MJ/kg.

  12. Conclusion • Increasing demand for portable electronics • Allows for real feasibility of electric vehicles. • With greater EESU efficiency, new applications now possible.
