GTRI_B-2
Carbon Nanotubes
• Elicarb• Dry - MWCNT• AQ – MWCNT• Dry – SWCNT• AQ - SWCNT
GTRI_B-3
Vacuum Pump
• Electric pump• Capable of pulling -80kPa
constantly• Simple switch on• Wore out
• Manual pump• Capable of sustaining -80kPa
once reached• Took 2 minutes of hand
pumping• Good workout
GTRI_B-4
Vacuum Beaker Setup
• Funnel holds CNT liquid• Pressure differential pulls liquid
through filter• Creates interwoven CNT mat once
dried• Can cause peeling
GTRI_B-5
Thermal Evaporated Aluminum
• Better contact between electrode and coin cell case
• Done in the Baker cleanroom
• Deposited ~300nm• Full evap. takes ~2hrs
GTRI_B-6
Room Temperature Ionic Liquid
• Cut filter into 13mm circles
• Applied 60µL-80µL
• RTIL’s Labeled by number (5, 6, 7, 8, 9, 11, 12)
47mm
13mm
GTRI_B-7
Coin Cell
• Coin cell• Two wave springs
for greater pressure• Spacer disks in
place to allow wave spring stability
• Contents on bottom for ease of fabrication
GTRI_B-8
Coin Cell Crimper
• Hohsen coin cell closing tool• Manual press• Bends corners
over gasket• Approx. 20/hr
GTRI_B-9
Finished Product
• Width = 3.28• Diameter = 20mm• Approx. Weight = 3.657g

Testing• Solartron
• Electrochemical interface tests• Impedance/Gain-Phase
Analyzer• Tests
• Constant Current• Constant Voltage• Impedance Spectroscopy
GTRI_B-12
Constant Current• Solatron supplies constant current (I = 0.001A)• Senses output voltage and graphs• Completely automated
process
GTRI_B-13
Impedance Spectroscopy
• Applies a voltage frequency scan• Senses gain and phase from supercap• Plots real, imaginary and amplitude

Data Analysis
• Specific Energy• E = (1/2)CV2
• Specific Energy = E/mass• Specific Power
• P = I2Rs
• Specific Power = P/mass
