NANO BATTERIES
By Soumya Yadala
UNIVERSITY OF TULSA
DEFINITION
Batteries that are fabricated employing technology at the nanoscale.
INTRODUCTION
Evolution of Nano batteries
Comparison of Lithium Ion Batteries & Nano Batteries
Li-Ion Battery:
Electrolyte : Ether
Anode : Lithium Cobalt Oxide.
Cathode : Graphite
Mechanism of Li-ion Battery
Solid Electrolyte Interface Barrier
Li-Ion Battery:
Drawback : The battery cannot be charged
at temperatures before 320 F. Reason : Due to the formation of solid electrolyte interface barrier.
Nano Battery:
Advantage : Electrode is made up of nanomaterial.
Result : No formation of solid electrolyte interface barrier.

Electrolyte
(Polymer battery: gel polymer electrolyte)
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.
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
Electronics
Defense Aerospace
Industrial
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:
Health care sectors
At University of Tulsa
Under Dr Dale Teeters from the Dept of Chemistry and Biochemistry.
Research and Development
Nano Battery:
Electrolyte : A wax solution of PEO and lithium triflate.
Anode : Vanadium Oxide
Cathode : Graphite
