A lithium-ion capacitor (LIC) is an advanced energy storage device that blends the properties of both capacitors and lithium-ion batteries, offering the best of both technologies. While traditional capacitors are known for their ability to deliver high power quickly, they have limited energy storage capacity.
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.
Also, the voltage discharge curves are different. A lithium ion battery tends to keep its voltage relatively constant until it's almost completely discharged. A capacitor under constant power load, on the other hand, drops in voltage rapidly. Suppose our load has a drop-out voltage of two volts.
To add to the answers above; Capacitors and Batteries are different inherently. Capacitors are built to be more "dynamical" electric devices. They have lesser energy density and voltage grows and depletes more rapidly on them. Batteries are built to be a more stable supply of voltage difference. There discharge is an inevitable inconvenience.

Engineers choose to use a battery or capacitor based on the circuit they’re designing and what they want that item to do. They may even use a combination of batteries and capacitors. The devices are not totally interchangeable, however. Here’s why. Batteries come in many different sizes. Some of the tiniest power small devices like hearing aids.
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.
