Provided by the Springer Nature SharedIt content-sharing initiative Lithium-ion capacitors (LICs) shrewdly combine a lithium-ion battery negative electrode capable of reversibly intercalating lithium cations, namely graphite, together with an electrical double-layer positive electrode, namely activated carbon.
The Li ion capacitor has the potential to neatly fill the energy density space between electrochemical double-layer capacitors (EDLC) and Li ion batteries. When researching new technologies like the Li ion capacitor, it is important to be cognizant of the possible restraints that might arise during the development of the manufacturing process.
Our research uncovers a unique approach based on the use of a lithiated organic material, namely 3,4-dihydroxybenzonitrile dilithium salt. This compound can irreversibly provide lithium cations to the graphite electrode during an initial operando charging step without any negative effects with respect to further operation of the LIC.
