Nano batteries are batteries fabricated using nanotechnology. They have electrodes made of nanomaterials which allows lithium ions to move faster between electrodes during charging and discharging compared to conventional lithium-ion batteries. This enables nano batteries to charge and discharge more quickly. Additionally, the use of nanomaterials prevents the formation of a solid electrolyte interface barrier that conventional batteries experience at high temperatures. Nano batteries could potentially be used in applications like electronics, defense, aerospace, industrial, and healthcare due to their faster charging capabilities and ability to operate at higher temperatures than conventional lithium-ion batteries.

2. INTRODUCTION
 Evolution of Nano batteries
DEFINITION
 Batteries that are fabricated employing technology at
the nanoscale.

3. Lithium Ion Battery Basics
 Electrochemical performance is determined by properties of the anode and cathode
materials.
 Currently, carbon is used as the anode material.
Li Ion Discharge
Electrolyte Cathode
 Charge battery (lithiation): large volume expansion 200-400% LiM
 Discharge battery (delithiation): volume contraction

4. Fabrication and Measurement
 Si NWs were synthesized using the VLS process on stainless steel
substrates using Au catalyst.
 The electrochemical properties were evaluated under an argon
atmosphere by both cyclic voltammetry and galvanostatic cycling in
a three electrode configuration, with the Si NWs on the stainless
steel substrate as the working electrode and Li foil as both
reference and counter-electrodes.

11.  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.

12.  Nano Battery:
 Advantage : Electrode particles are non-structured.
 Result :
• Shortens the existing distance with in the
electrode material.
• Accelerates the recharging and discharging
rate.

13. 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.
