There are several approaches for anode pre-lithiation described in literature, focusing on graphite, silicon, lithium-titanate (LTO) electrodes and even on lithium-ion capacitors (LiC) [22, 23].
Similar to lithium-ion batteries (LIBs), during the first charge/discharge process of lithium-ion capacitors (LICs), lithium-intercalated anodes (e.g., silicon, graphite, and hard carbon) also exhibit irreversible lithium intercalation behaviors, such as the formation of a solid electrolyte interface (SEI), which will consume Li + in the electrolyte and significantly reduce the electrochemical

Lithium ion capacitors (LICs) can generally deliver higher energy density than supercapacitors (SCs) and have much higher power density and longer cycle life than lithium ion batteries (LIBs). Due to their great potential to bridge the gap between SCs and LIBs, LICs are becoming important electrochemical ene
In this progress report, we first classify LICs according to their energy storage mechanisms and discuss the multiple roles that the pre-lithiation technologies play for improving the performance of LICs. Then, we present the existing pre-lithiation methods used in LICs in detail and the current research progress is summarized.

Inspired by the pre-lithiation technique developed by JM Energy in Japan, which enables a full pre-lithiation of carbon anodes (i.e., to form the LiC 6 state at the graphite anode) in Li-ion capacitors (LICs) to lower the electrode potential of carbon anode, an improved pre-lithiation of graphite anodes using through-holed cathode and anode
Dimetal squarates including dilithium, disodium and dipotassium squarate salts (Li 2 C 4 O 4, Na 2 C 4 O 4 and K 2 C 4 O 4) were used as sacrificial salts in AC//HC metal ion capacitors, such as lithium-ion, sodium-ion and potassium-ion capacitors, respectively, resulting from its highly efficient and industrially compatible low-cost property as shown in Fig. 8 g [199].
Lithium-ion capacitors (LICs) bridge the gap between lithium-ion batteries (LIBs) and electrical double-layer capacitors (EDLCs) owing to their unique energy storage mechanisms.

Lithium-ion capacitors offer superior performance in cold environments compared to traditional lithium-ion batteries. As demonstrated in recent studies, LiCs can maintain approximately 50% of their capacity at temperatures as low as -10°C under high discharge rates (7.5C). In contrast, lithium-ion batteries experience a significant reduction in capacity, dropping to around 50%
