Information


 

A lithium-ion capacitor (LIC) is a hybrid type of capacitor classified as a type of supercapacitor. Activated carbon is typically used as the cathode. The anode of the LIC consists of carbon material which is pre-doped with lithium ions. This pre-doping process lowers the potential of the anode and allows a relatively high output voltage compared with other supercapacitors.

 

Features

  • High capacitance compared to a capacitor, because of the large anode, though low capacity compared to a Li-ion cell
  • High energy density compared to a capacitor(14 Wh/kg reported), though low energy density compared to a Li-ion cell
  • High power density
  • High reliability
  • Operating temperatures ranging from 20 °C to 70 °C
  • Low self-discharge (<5% voltage drop at 25 °C over three months)

 

Applications

Lithium-ion capacitors are quite 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.

Potential applications for lithium-ion capacitors are, for example, in the fields of wind power generation systems, uninterruptible power souce systems (UPS), voltage sag compensation, photovoltaic power generation, energy recovery systems in industrial machinery, and transportation systems.
