Recently, considerable attention has been devoted to the lithium-ion capacitor (LIC) as a promising energy-storage device with high-power and high-energy density. The feature of higher energy density than electric double layer capacitor (EDLC) makes the LIC suitable for use in energy-storage applications with renewable energy sources. The most challenging issue in the development of a self-sustaining LIC is pre-lithiation of the negative electrode without using lithium metal prior to cell operation. The concept of adding a transition metal oxide as an alternative lithium source in the positive electrode has been proposed to resolve this matter. While the proposed concept was successfully implemented, the achievable capacitance of advanced LIC is still limited in terms of meeting the requirements for commercial use. In pursuit of further improvement of energy density, we report a new additive and discuss the possibility and limitations of it from an electrochemical and structural perspective.
