Lithium-ion capacitors (LiC) are promising hybrid devices bridging the gap between batteries and supercapacitors by offering simultaneous high specific power and specific energy. However, an indispensable critical component in LiC is the capacitive cathode for high power.
Design of Lithium-Ion Capacitors In terms of LIC design, the process of pre-lithiation, the working voltage and the mass ratio of the cathode to the anode allow a difference in energy capacity, power efficiency and cyclic stability. An ideal working capacity can usually be accomplished by intercalating Li + into the interlayer of graphite.

Lithium-ion capacitors offer superior performance in cold environments compared to traditional lithium-ion batteries. As demonstrated in recent studies, LiCs can maintain approximately 50% of their capacity at temperatures as low as -10°C under high discharge rates (7.5C).
LIC's have higher power densities than batteries, and are safer than lithium-ion batteries, in which thermal runaway reactions may occur. Compared to the electric double-layer capacitor (EDLC), the LIC has a higher output voltage.
This review will focus on the LIC developments as the main example of a hybrid capacitor, but it must be noted that there are many similarities between LICs, NICs and KICs. LIBs normally have high energy density (>150 W h kg −1) and have no memory impact as in conventional Ni-Cd/Ni-MH batteries [5, 6].

Lithium-ion capacitors are fairly suitable for applications which require a high energy density, high power densities and excellent durability. Since they combine high energy density with high power density, there is no need for additional electrical storage devices in various kinds of applications, resulting in reduced costs.
