INTRODUCTION

• Evolution of Nano batteries

DEFINITION

• Batteries that are fabricated employing
  technology at the nanoscale.

Comparison of Lithium Ion Batteries Nano
Batteries

• Li-Ion Battery

• Anode Lithium Cobalt Oxide.

• Cathode Graphite

• Electrolyte Ether

Solid Electrolyte Interface Barrier
6

• Li-Ion Battery

• Drawback The battery cannot be charged
• at temperatures before
  320 F.

• Reason Due to the formation of solid
• electrolyte interface
  barrier.

7

• Nano Battery

• Advantage Electrode is made up of
• nanomaterial.

• Result No formation of solid electrolyte
• interface barrier.

• Li-Ion Battery

• Drawback These batteries are slow to
• charge and discharge.

• Reasons
• Due to the long distance Li-ions have to travel
  through the electrode material in the battery.
• Speed at which the Li-ions make their way through
  the electrode material is also slow.

10

• Nano Battery

• Advantage Electrode particles are non-
• structured.

• Result
• Shortens the existing distance with in the
  electrode material.
• Accelerates the recharging and discharging rate.

Applications of Nano Battery
The Nanotechnological Batteries make every thing
possible from a hybrid vehicle capable of giving
150 miles/gallon to battery powered fabrics which
enables soldiers to plug electronic devices into
their uniform. The nanobatteries to be more
specific has the potential to be used in the
following fields

• Electronics

• Defense

• Aerospace

• Industrial

• Health care sectors

12
Research and Development

• At University of Tulsa

• Under Dr Dale Teeters from the Dept of Chemistry
  and Biochemistry.

13

• Nano Battery

• Anode Vanadium Oxide

• Cathode Graphite

• Electrolyte A wax solution of PEO and
• lithium triflate.

14

• Charging and Testing

• Atomic force microscope

• AC Impedance
