ABSTRACT
This chapter discusses fabrication of lithium-ion supercapacitors (LISCs). Generally, LISCs are based on faradaic process and non-faradaic process to store Li-ions. The chapter focuses on the combination of the faradaic electrode and the non-faradaic electrode. It describes how the Li-ion capacitor is fabricated, especially introducing faradaic cathode materials and anode materials coupled with non-faradaic materials, which are activated carbons. The development on the non-faradaic side not only focuses on higher surfaces, more suitable porous structure, and higher conductivity of activated carbons, but also attempts to discover new carbonaceous material for higher electrical double-layer capacitance. For electrode preparation, cathode material and anode material are grounded into a powder with a small particle size by a ball milling machine. After the electrodes are dried, they are cut into different shapes by cutting machine based on the requirement. For the activated carbon, high energy density to be paired up with faradaic electrode is the direction researchers should follow.
