A lithium-ion or asymmetrical capacitor is much like an ultra capacitor or super capacitor with the addition of higher rated voltage (3.8V), two or more times the stored energy and a low self discharge rate similar to that of a lithium-ion battery. Ultracapacitors are made up of two layers of double-sided electrode. The electrode is made with carbon laminated to both sides of an aluminum foil. The two layers are then rolled together and sealed in a can with special electrolyte. Lithium-ion capacitors (LIC) have a similar double sided carbon laminated aluminum foil cathode along with a double sided graphinic laminated copper foil anode doped with small amounts of lithium sealed in a can with special electrolyte.
Lithium-ion or Asymmetrical Capacitor Advantages:
Our signature product, LICAP’s Lithium-Ion Capacitor (LIC) has 2-3 times the energy density of standard ultracapacitor products while maintaining a high (up to 50C) charge and discharge rate compared to lithium-ion batteries (LIB). Like ultracapacitors, our LIC products will also operate for over 500,000 cycles, with a calendar life greater than 10 years.
Compared to a typical LIB, the LICAP LIC has similar operating voltages, similar self-discharge, is inherently safer, and 1000 times the cycle performance.
This is our first product in the category and we are currently developing a range of new LIC cells from 3.8V 800F to 3.8V 4500F to follow this year. These products are all made possible by our industry leading Activated Dry Electrode.
