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.
