Electrolytic Capacitor Electrolytic capacitors are capacitors that exist in two forms: non-polar and polar. The anode of these capacitors typically comprises metal foil, such as aluminum or tantalum, with an oxide film, often aluminum oxide or tantalum pentoxide, serving as the dielectric and adhering closely to the anode.
For this aim, the lithium-ion capacitors (LiC) have been developed and commercialized, which is a combination of Li-ion and electric double-layer capacitors (EDLC). The advantages of high-power compared to Li-ion properties and high-energy compared to EDLC properties make the LiC technology a perfect candidate for high current applications.
