Lithium-ion capacitors (LICs) are asymmetric electrochemical supercapacitors combining the advantages of high power density and long cycle life of electrical double-layer capacitor (EDLC), and high energy density of lithium-ion battery.

A lithium-ion capacitor (LIC) is a type of supercapacitor. It''s a hybrid between a Li-ion battery and an electric double-layer supercapacitor (ELDC). The cathode is activated carbon, the same as is found in an ELDC, while the anode consists of carbon material pre-doped with lithium ions, similar to those found in Li-ion batteries.
When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q. To explain, first note that the charge on the plate connected to the positive terminal of the battery is (+Q) and the charge on the plate connected to the negative terminal is (-Q). That is, all capacitors of a
A capacitor across a battery is almost completely useless. The only way to extract energy from a capacitor is to allow its voltage to vary, which requires a DC-DC converter between the capacitor and a constant voltage bus. By the time you''re done, you will have spent more money than the cost of a decent, high power battery. So, not worth it.
