Electrochemical performance of lithium-ion capacitors using pre-lithiated multiwalled carbon nanotubes as anode

Internal short-circuit method (ISC) is also called direct

a

contact (DC) method. The pre-lithiated can achieved through direct physical contact between negative electrode and lithium metal with electrolyte in pressure.

In this method, the pre-lithiation process was completed by a self-discharge mechanism. Electrons will pass through the contact point between the lithium metal and anode in the effect of potential difference. The process of ISC is simple, fast and controllable.

In this paper, Pre-lithiated multiwalled carbon nanotubes and activated carbon(AC) materials were used as anode and cathode respectively for Lithium-ion capacitors (LICs). Pre-lithiated multiwalled carbon nanotube anode was prepared by internal short circuit approach (ISC).LICs have higher power density than lithium-ion batteries and higher energy density than the electric double layer capacitors(EDLCs).
