ESD Hybrids: EDLC|Batteries

The SAMWHA ESD-SCAPs are promising energy storage devices that technically lie between conventional EDLC and lithium-ion batteries. The high energy and power density, as well as the long life of the hybrid and battery capacitors allow their use in a wide range of applications.

Questions & answers about hybrid cap technoloy

  • For which applications hybrid supercaps are ideally meant for?

    Hybrid capacitors are ideally used where higher energy densities are required in combination with high power density (C-rate up to 34) in a confined space. Although HybridCaps have a lower cycle resistance of >50000 cycles and a lower power density than EDLC, there are many applications where these criteria are of secondary importance. Examples are flashlights (quickly rechargeable), tools, robots, transport systems (AGV or AGV). As a back-up system in industrial control systems and much more. Several tens of thousands of charging and discharging cycles mean that for many devices their service life has already been exceeded due to other criteria. The decisive factor is therefore the application criteria that are defined during product definition.

  • How does a hybric utracap cap work?

    Lithium-ion capacitors (LIC) belong to the family of supercapacitors and are hybrid capacitors with asymmetrical electrodes. They combine a static double-layer electrode (as in EDLC) with an electrochemical redox electrode doped with embedded lithium ions, both of which are electrically connected to each other by a lithium-containing electrolyte. When a voltage is applied to the capacitor, the charge carriers in the electrolyte separate into their positive cations and negative charges anions. At the positive electrode of a HybridCap, which usually consists of activated carbon, the anionic charges then accumulate statically on the double layer during charging of the capacitor, depending on the voltage. Thus an internal capacitor is formed at the positive electrode of the LIC with the capacitance resulting from the surface of the electrode and the distance given by the double layer.

  • What exaclty means hybrid ultracap ?

    The hybrid capacitor manufactured with Li4Ti5O12 = lithium titanate oxide as anode material has a higher energy density than an electrical double layer capacitor (EDLC). The hybrid capacitor is a capacitor that uses different materials with different operating potentials as cathode (activated carbon) and anode (Li4Ti5O12), which can increase the total cell potential, resulting in higher energy and power densities. EDLC or double layer capacitors have activated carbon as base material and ACN = acetone-nitrile as electrolyte.
