Welcome to the CDE EDC/EDS coin cell Series Supercapacitor Training Module
This presentation will describe the features and capabilities of a new line of coin cell style supercapacitor that combine cost effectiveness with a very high level of performance. Potential applications for coin cell supercapacitors, such as the EDC/EDS coin cell Series, will also be outlined.

2. Why supercapacitors
Bridge the gap between batteries and standard electrolytic capacitors

3. Supercapacitor Construction
Activated Carbon electrodes
Aqueous and non aqueous electrolyte (ACN, PC)
No dielectric like standard capacitors
Energy stored in carbon/ electrolyte interface area. (Electric Double layer)

4. Comparison to Batteries and Capacitors
Rechargeable Batteries
Highest stored energy
Long discharge time (1 – 3 hours)
Cycles (<10,000)
Supercaps
High power density
Short charge/discharge time (seconds)
Cycles (>1,000,000)
Capacitors (Aluminum Electrolytic)
Highest Power
Highest temperature Range
Lowest Stored Energy
Unlimited cycling

5. General Uses for Supercapacitors
Due to their much faster charge/discharge times and number of cycles permitted, supercaps are being used in place of batteries to provide frequent short bursts of energy.
When supercapacitors are placed in parallel with batteries they reduce the stress on the battery by providing quick bursts of energy to the load. This greatly extends battery life and lowers overall costs.
Provide sustained memory backup during power outages without use of batteries

6. EDC/EDS coin cell Series Supercapacitors offer unique advantages.
The EDC/EDS coin cells are very compact, high-capacitance devices. Compared to traditional electrolytics or rechargeable batteries, the EDC/EDS coin cells are…
Electric double-layer capacitors (EDLC), with very large storage capabilities and low ESR
Designed around an activated carbon anode and cathode, with an organic electrolyte
Especially well suited for circuits requiring fast response time
Fast charging, with long life energy storage
Supercapacitors, sometimes called double-layer or ultra-capacitors, are special types of capacitors that have capacitance values far greater than conventional electrolytic capacitors.
CDE’s EDC/EDS coin cell series is such a device, offering many times the storage capacity of common electrolytics. Its design is based on a structure having an activated carbon anode and cathode, with an organic electrolyte. Unlike a rechargeable battery, a EDC/EDS coin cell capacitor is especially well suited for providing short, high-power bursts of energy. Recharging is ultra-fast, with long life energy storage.

7. EDC/EDS Coin Cell Series Supercapacitors offer high capacitance, low ESR and compact size.
Lines include values from to 1.5 Farads
3.6, 5.5, 6.3 WVDC Max
Operating temperature ranges from:
(EDS Series) -25 °C to +85 °C
(EDC Series)
-25 °C to +70 °C
Long life--rated at over 500,000 charge/discharge cycles
Performance does not degrade with each cycle
Very compact size
Connect in series or parallel for even higher voltage or capacitance
Direct replacement for recently discontinued devices of similar values from Panasonic and others
CDE coin cells are available with storage up to 1.5 Farads, with low ESR.
Voltage ratings are 2.7WVDC for a single device or 6.3WVDC for a dual device. The wide temperature operating range adds to application diversity.
Rated operating life is especially long, offering over 500,000 charge/discharge cycles. And unlike a battery, performance does not degrade with each cycle.
With compact size, it is practical to use multiples for increased voltage or capacitance.
EDC/EDS Series supercaps can be used as direct replacements for a number of similar size devices recently discontinued by other manufacturers.

8. EDC/EDS Series Key Specifications
Key specifications for the EDC/EDS coin cell Series Supercapacitors illustrate the wide range of applications that are a good fit for its characteristics.
With an operating temperature range of minus 25 degrees C to 75 or 85 degrees C at maximum WVDC, outdoor applications are no problem.
The long life and multiple cycle performance provides excellent performance for both consumer and commercial products.

9. Choose from 26 different SKUs… 0. 047 to 1. 5 Farads, at 3. 6, 5
Choose from 26 different SKUs… to 1.5 Farads, at 3.6, 5.5 or 6.3VDC
EDC/EDS coin cell Series Supercapacitors are available in 26 different capacitance values up to1.5 Farad volt rated capacitors are radial leaded and internally made up of two devices.
A detailed look at the specifications will illustrate the low ESR, exceptionally high energy density and maximum stored energy. Unlike conventional aluminum electrolytic capacitors, specifications are also provided for Energy Volumetric Density, Power Density, and Power Volumetric Density.

10. Configurations and Termination Options
Standard packaging and lead configurations for the EDC/EDS coin cell Series for the 2.7 volt and 6.3 volt types are shown here.
For applications requiring higher voltage and capacitance, modules can be created with an array of board-mounted devices. This can be done with balancing circuitry by the user or by CDE.
