LIC Hybrid Caps vs EDLCs
Battery capacitors: The lithium ion capacitor LIC
Battery capacitors are supercapacitors, but technically fall into the category of lithium ion capacitors or LIC for (Lithium Ion Capacitor). This technology complements and expands the range of applications of SUPERCAPs. The hybrid capacitor, made with Li4Ti5O12 = lithium titanate oxide as the 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 (e.g. 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. The diagrams clearly show the essential differences.
Better performance with EDLCs - Higher energy density with LIC hybrids
EDLC have the significantly better performance data, hybrid capacitors have a significantly higher energy density. At the same time, however, due to the lithium base, they are not as cycle-resistant as the EDLC. However, this does not play such an important role in all applications. Both technologies complement each other, depending on the application. The decision for or against a technology is decided by the application.
