2 What is a Super capacitor? When two different phases of solid and liquid come into contact, positive and negative charge are distributed confronting each other in a very small distance on the boundary surface. A layer which spreads in the vicinity of this boundary surface is called the Electrical Double Layer. Electric Double Layer Conventional type of Caps Electro Double Layer Capacitor Rechargeable Battery 1uF 10mF 1F 100F 10000F 2

3 What is EDLC (Super capacitor)? Power Density (W/kg) Al electrolytic capacitor Electric Double Layer Capacitor (EDLC, Supercap) Secondary Battery Energy Density (Wh/kg) EDLC: Relatively High Energy Density & High Power Density 3

4 Comparison of Energy Storage Devices Energy Storage Principle Operating Temperature Super Capacitors Aluminum Electrolytic Caps Electric Double Layer Dielectric Polarization Ni-Cd Batteries Chemical Reaction Lithium Rechargeable Batteries Chemical Reaction -40 C to 85 C -40 C~+105 C -10 C to 65 C -20 C to 50 C Working Voltage 1.8V to 18V 6.3V~ 1.2V ~3V Energy Density (Wh/kg) < Charging time Several seconds Several seconds Several hours Several hours Charging Current Limitation Restrictions on Charge/Discharge Automated Mounting Material Safety Failure Mode None None Limited Limited Infinite Infinite Limited 1000 times Applicable (FC & FM series) No harmful Material Open Nothing further (safe) Limited 1000 times Applicable Not Applicable Not Applicable No harmful Material Short Heating, Explosion Cadmium Short Heating, Explosion No harmful Material Short Ignition, Explosion Liquid leakage 4

5 Battery or Super cap? - Super cap Advantages Maintenance free Simple installation (5.5V SMD available) Wide operating temperature -40 C to 85 C Available Quick charging Infinite Charge/Discharge cycle Open Failure Mode No damage with reverse voltage (No polarity except Organic Electrolyte type) Environmentally Friendly-No use of hazardous material such as Cd and Pb 5

6 Why NEC TOKIN Super capacitor? NEC TOKIN Competitors Temperature Widest Operating Temp. Range -40ºC ~ +85ºC 5.5V Rating -20ºC ~70ºC -40ºC ~ 3.5V, limited voltage condition Life Moisture, Shock Resistant Rubber Vulcanization Process Sealing Longer life: Aqueous Type Gasket Sealing Weak for Moisture, Shock Shorter life: Organic Type Cost Saving Mounting Cost SMD 5.5V Product Available SMD 3.5V rating only. Failure Mode OPEN Short 6

8 NEC TOKIN Advantages in Derating NEC TOKIN: Cell structure Max. voltage per cell = 1.2Vmax/cell Conductive Current Collecting Electrode Conductive current collecting Synthetic rubber for sealing Sealing synthetic Separator Activated carbon + Electrolyte (Dilute Sulfuric Acid) Aqueous type (5.5V rated part) Separator (porous organic film) Activated carbon + electrolyte (dilute sulfuric acid) Competitor: Cell structure Max. voltage per cell = 3.0Vmax/cell Activated carbon Cap Case ケース Separator Gasket sealing Organic type (5.5V rated part) 2.750V/cell 2.750V/cell 2 cells About 30% margin/cell 6 cells Can case type About 8% margin/cell Coin type

9 NEC TOKIN Advantages in Sealing NEC TOKIN: Aqueous type basic cell structure; Competitor: Organic type basic cell structure Rubber cross-link bonding Conductive current collecting electrode Sealing Synthetic Rubber Separator (Porous Organic Film) Activated Carbon + Electrolyte (Dilute Sulfuric Acid) Activated carbon + Aqueous electrolyte Tight sealing by rubber cross-link bonding. Aqueous electrolyte = High moisture resistance Cross-link bonding = Strong shock resistance Cap Electrode Gasket (Packing) Porous Separator Electrode Case Gasket packing Activated carbon + Organic electrolyte Gasket packing sealing Organic electrolyte = Low moisture resistance Gasket packing = Low resistance to shock

10 Life Time Comparison Supercap vs. Organic Type Electric Double Layer Capacitor Supercapacitor NEC/TOKIN Aqueous Type EDLC has LONGER life. Organic Type Electric Double Layer Cap 10

11 Open Failure Mode Open Failure Mode Does not damage other components in circuit No heat generated What happens: Gas forms in electrode, between the electrode and activated carbon remained The remained activated carbon increases ESR, finally opened circuit No leakage of acid COMPETITION: Conductive Current Collecting Electrode Activated Carbon & Dilute Sulfuric Acid, H2SO4 Sealing is broken down and causes leakage, finally causes a short circuit.
