A lithium-ion capacitor (LIC or LiC) is a hybrid type of capacitor classified as a type of supercapacitor. It is called a hybrid because the anode is the same as those used in lithium-ion batteries and the cathode is the same as those used in supercapacitors. Activated carbon is typically used as the cathode.
However, in the present state of the art, both devices are inadequate for many applications such as hybrid electric vehicles and so on. Lithium-ion capacitors (LICs) are combinations of LIBs and SCs which phenomenally improve the performance by bridging the gap between these two devices.
Conceptual presentation of fabrication with Li-ion capacitors. Li-ion battery (LIB) is a rechargeable energy storage device, where lithium ions are inserted and extracted into/from the negative electrode while charging and discharging (Fig. 2). The basic difference in the SC and LIB is their charge storage mechanism.
Some LIC's have a longer cycle life but this is often at the cost of a lower energy density. In conclusion, the LIC will probably never reach the energy density of a lithium-ion battery and never reach the combined cycle life and power density of a supercapacitor.
Lithium-ion batteries (LIBs) and supercapacitors (SCs) are well-known energy storage technologies due to their exceptional role in consumer electronics and grid energy storage. However, in the present state of the art, both devices are inadequate for many applications such as hybrid electric vehicles and so on.
As explained in the previous section, the LIC consists of an EDLC cathode material, a pre-lithiated LIB anode material and an organic electrolyte containing lithium ion .
How to Quickly and Safely Charge Supercapacitors
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.

We may be underestimating the power capabilities of lithium-ion capacitors
Commercial lithium-ion capacitors include lithiated graphite and activated carbon. Power capabilities of lithium-ion capacitors are often understated in literature. Arguably, power densities of lithium-ion capacitors may be superior to those of supercapacitors. A slow charge of lithium-ion capacitors may increase power characteristics further.
